has the highest maximum lot size for overseas forex tradingAXIORYat 1,000 lots," "XM has 50 lots," "FXGThas 100 lots"—if you look it up, you'll find figures for each broker, butif you place a large order according to those figures, you may hit another limit and be rejected. This isbecause the "maximum lot size" refers only to the limit for a single order, and there are other limits for the entire account, as well as limits that vary depending on the currency pair and time zone.
This article detailsof 11 overseas forex brokers,Exnessaccessed on October 1-2, 2026, to verify the maximum lot size per order, minimum lot size, maximum number of positions, and overall account limits for each account type. Based on this, we explain the "three limits" to consider for large-volume trades, as well as how to calculate lot sizes (correcting calculation errors in previous versions), with source URLs and verification dates included.
Conclusion | Key Points Regarding Maximum Lot Sizes in Overseas Forex Trading (As of October 2026)
- The maximum lot size per order varies from 30 to 1,000 lots across 11 companies.The largest isAXIORYwith 1,000 lots (all accounts, per position), followed byExness 200 (daytime, 2023 help),FXGT ECN ZERO 120, andFXGT OPTIMUS,AxiMajor, and TitanFX FX with 100 lots each.
- The maximum lot size is determined by three limits:① the limit per order, ② the overall account limit (number of positions x lots, or per account), and ③ limits that vary depending on the currency pair, time zone, and account type. Large orders tend to bottleneck ② and ③.
- Even within the same broker, account types differ.FXGToffers STANDARD 50/PRO 60/OPTIMUS 100/ECN ZERO 120 lots,IS6FXoffers Standard 30/Pro Zero 50/Micro 100 lots. XM offers Standard 50 and Micro 100, but KIWAMI and Zero are not listed on their official website.
- Few brokers publicly disclose the maximum trading volume for their entire account.ThreeTraderstates "80 lots x 200 positions = 16,000 lots,"FXGTstates 200 lots per account, andHFM CENT states 6,000 cents for the entire account.AXIORYandBigBossexplicitly state "no limit."
- Some brokers have lower limits depending on the currency pair and time zone.Axihas 100 major/50 minor/20 exotic lots,BigBosshas 50 major/20 minor/5 exotic lots,Exnesshas 200 lots during the day and 20 lots at night (GMT+0).
- The minimum lot size is 0.01 lots (1,000 units of currency) as standard.However, in a micro-cent account, 1 lot = 1,000 units of currency, so even a "maximum of 100 lots" is equivalent to 100,000 units of currency, which is equivalent to 1 standard lot. Compare lot sizes after ensuring that the amount of currency per lot is the same.
- What matters most is your own margin, rather than the broker's limit.Even with approximately $6,250 leveraged at 1,000x, you can only open 66.66 lots (USD/JPY at approximately $0.94). 1,000 lots would require approximately $93,750 in margin.

The table has three main points
- The highest order limit per trade isAXIORY's 1,000 lots. This is followed byExness(200 lots per day, as of 2023),FXGT ECN ZERO 120, andFXGT OPTIMUS,AxiMajor, and TitanFX FX, all with 100 lots.IS6FX's standard account has a limit of 30 lots
- You can't simply say "broker = one number.FXGThas 50-120 lots depending on the account type,AxiandBigBosshave 5-100 lots depending on the currency pair, andExnesshas 20-200 lots depending on the time of day—a difference of 2 to 10 times within the same broker.
- publicly disclose their overall account limitsThreeTrader(16,000 lots),FXGT(200 lots per account),HFM CENT (6,000 cents), andIS6FX(30 positions).AXIORYandBigBossexplicitly state "no limit."
The minimum lot size is 0.01 lots = 1,000 currency units for all companies, with the exception of TitanFX's Micro account (0.1 micro lots = 100 currency units), XM Micro (0.01 lots = 10 currency units in MT4,HFM 0.1 lots = 100 currency units in MT5),IS6FX) CENT (0.01 lots = 10 currency units), and Micro ( 0.05 lots = 50 currency units . The differences in lot units between accounts will be explained in the section on 1 lot
How to understand the maximum lot size in overseas forex trading: "Three limits" | Limits that vary depending on the order, the entire account, and the conditions
The number presented as "maximum XX lots" is almost always the "maximum amount that can be placed in a single order." The real bottlenecks in large-volume trading are the other two limits—the total account holding limit and the limit that varies depending on the currency pair, time zone, and account type
① Order limit per order: Varies depending on account type, not determined by broker name alone
The official websites use different terms for "Maximum Order Lot (per position)" (AXIORY), "Minimum/Maximum Trade Size" (FXGT), "Maximum Trade Quantity (lots)" (AXIORYCFD), "Maximum Trade Volume (per position)" (IS6FX), "Maximum Total Trade Size (lots): 60 standard lots per position" (HFM), and "Maximum Trade Volume (per position)" (IS6FX), but all of these representthat can be placed in a single trade.FXGThas STANDARD 50, PRO 60, OPTIMUS 100, and ECN ZERO 120,IS6FXhas Standard 30, Pro Zero 50, and Micro 100.When "Broker Name = Single Number" is shown in the comparison table, please check which account type the value corresponds to.
② Account-wide limit | Number of positions × Lot size, or per-account limit
Orders exceeding the maximum limit per order are split into multiple orders, but there are limits to these splits.ThreeTraderexplicitly states in its official media that "a maximum of 16,000 lots (80 lots x 200 positions) can be held,"FXGTsets a maximum of 200 lots (500 lots for MINI) and 100-200 positions for each account type.HFM's CENT account allows "1000 cent lots per position / 6000 cent lots for the entire trading account," andIS6FXhas a limit of 30 positions (including pending orders) for all accounts. On the other hand,AXIORYhas "no limit on the maximum number of positions," andBigBossexplicitly states that "there are no limits on the maximum number of positions or the number of lots that can be held."If you are trading in large quantities, you should look at the overall account limit before the limit on a single order.
③ Upper limits vary depending on conditions: currency pair category, time zone, lot size
- Currency pair classifications:Axioffers 100 major lots, 50 minor lots, and 20 exotic lots;BigBossoffers 50 major lots, 20 minor lots, and 5 exotic lots. The "maximum 100 lots" is for major pairs; exotic pairs like USD/TRY are one-fifth of that.
- Time zone:Exness's official help page (as of June 2023), the trading hours are "7:00 – 20:59 (GMT+0): 200 lots / 21:00 – 6:59 (GMT+0): 20 lots". This means 20 lots during the morning to afternoon hours (6:00 to 15:59 Japan time).
- Lot size: XM Micro,IS6FXMicro, TitanFX Micro, andHFM CENT use 1 lot = 1,000 currency units, whileFXGT MINI uses 1 lot = 10,000 currency units. Sometimes, "maximum 100 lots" only means 100,000 currency units (equivalent to 1 standard lot) (due to differences in the currency unit per lot)
- Product categories: TitanFX offers 100 lots of FX, 50 lots of metals, 20 lots of energy, and 10 lots of cryptocurrenciesAxioffers 20 lots of precious metals and up to 1,000 lots of stock indices depending on the instrument. Different limits apply to all other categories.

AXIORY| 1,000 lots per position for all account types, no limit on the number of positions held
AXIORYhas the largest minimum trading lot size among the 11 companies we checked, at 1,000 lots (per position), and there is "no limit" on the maximum number of positions held.On their official account type page, all five account types—Zero, Max, Standard, Nano, and Terra—are unified with "minimum trading quantity (lot) 0.01 / maximum order lot (per position) 1,000 / trading unit (FX) 1 lot = 100,000 / maximum number of positions held no limit." Only the Alpha account (MT5) for spot stocks and ETFs has a minimum trading quantity of 1 and a maximum order lot of 100,000 (FX trading unit is indicated with "-"). Please note that the official FAQ explains 1,000 lots (XAUUSD) for precious metal CFDs as the "total number of lots held," and states that for stock index CFDs and stock CFDs, "the maximum number of lots varies depending on the instrument" (e.g., JP225 is 10,000, US30 is 400). Therefore,please interpret 1,000 lots as the maximum order limit for a single FX currency pair.

Overseas Forex Trading: 1 Lot and Minimum Lot | 100,000 Currency Units is the Basic Unit, Micro, Cent, and MINI are Different Units
In overseas forex trading, one lot (a unit of currency traded) is generally 100,000 units of currency, with a standard minimum lot size of 0.01 lots (1,000 units of currency). However, micro accounts, cent accounts, andFXGT's MINI account have different lot sizes, so simply comparing lot numbers can lead to a miscalculation of trading volume by up to 100 times
1 lot = 100,000 units of currency | 10 times more than 10,000 units of currency in domestic FX
In a standard overseas forex account,1 lot equals 100,000 units of currency.AXIORYexplains in its official FAQ that "1 lot = 100,000 units of currency = 10 lots. The minimum trade size is 0.01 lots = 1,000 units of currency = 0.1 lots." Buying 1 lot of USD/JPY means buying 100,000 dollars, anda price movement of 1 pip (approximately $0.00)results in a profit or loss of approximately $6.25. This is 10 times more than the "1 lot = 10,000 units of currency" common in domestic forex, so those who have switched from domestic forex should pay attention to the magnitude of the order quantity.
The MicroCent MINI account has a different "currency volume per lot"
In accounts designed for small amounts, the lot size itself is set to be smaller. Even if the maximum is the same "100 lots," the amount of currency can differ by a factor of 100
| account | Currency volume per lot | Minimum lot size | Minimum lot size | Maximum lot size per order | Maximum lot size (standard conversion) |
|---|---|---|---|---|---|
| XMTrading Micro | 1,000 units of currency (1 micro lot) | 0.1 lot (MT5) / 0.01 lot (MT4) | 100 currencies/10 currencies | 100 lots | 100,000 units of currency (equivalent to 1 lot) |

This difference is also the reason why comparison tables on other sites show both "XMTrading's maximum lot size is 100" and "50" . On the official page, the Standard account has a "maximum trade size of 50 lots," and the Micro account has a "maximum trade size of 100 lots." However, 100 lots in the Micro account is only equivalent to 100,000 units of currency, which is just 1 lot in the Standard account. When comparing lot sizes, be sure to make sure thatHFM CENT and XM Micro (MT4) can be traded from as little as 10 units of currency, andIS6FXMicro from 50 units of currency. How to start with a small amount the amount of currency in 1 lot is the same . The same applies to the minimum lot size; is explained in detail in the section on minimum deposits for overseas FX
How to Calculate Lot Sizes in Overseas Forex Trading | Maximum Trading Lot Size, Required Margin, and Appropriate Lot Size
Lot size calculations for overseas forex trading are done in three ways: "the maximum trading volume," "the required margin when trading with the broker's maximum lot size," and "the appropriate lot size calculated backward from your risk tolerance."All calculations were verified by our editorial team, assuming 1 lot = 100,000 units of currency, USD/JPY = 1 dollar approx. $0.94, and a minimum unit of 0.01 lots.
① Maximum trading lot = Effective margin × Leverage ÷ (Rate × 100,000 units of currency)
When trading USD/JPY with an effective margin of approximately $625.00 and leverage of 1,000x, the required margin per lot isapproximately $0.94 x 100,000 units ÷ 1,000 = approximately $93.75. Therefore, you can open up to approximately $625.00 ÷ approximately $93.75 =6.66 lots(rounded down to the nearest 0.01 lot).
| Effective margin | Leverage 1,000x | 500x leverage | 200x leverage |
|---|---|---|---|
| approx. $625.00 | 6.66 lots | 3.33 lots | 1.33 lots |
| approx. $6,250 | 66.66 lots | 33.33 lots | 13.33 lots |
| approx. $62,500 | 666.66 lots | 333.33 lots | 133.33 lots |
*USDJPY = approx. $0.94, 1 lot = 100,000 units of currency, rounded down to the nearest 0.01 lot. Calculated by our editorial team. Since leverage decreases with account balance for many brokers, please check the actual maximum leverage by account balance for each company (comparison of leverage for overseas FX).
This calculation shows thateven with approximately $6,250 leveraged at 1,000x, the maximum number of lots is around 66.ReachingAXIORY's 1,000 lots orFXGT OPTIMUS's 100 lots, requires capital in the tens of millions of yen. For most traders, what matters first is their own margin, not the broker's maximum lot size.
② How much margin is required when trading with the broker's maximum lot size?
| Maximum order quantity per order (example) | amount of currency | Required margin (1,000x) | Profit or loss of 1 pip |
|---|---|---|---|
| 1,000 lots (AXIORY) | 100 million currency | approx. $93,750 | approx. $6,250 |
| 200 lots (ExnessJapan - 2023 Help) | 20 million currency | approx. $18,750 | approx. $1,250 |
| 100 lots (TitanFX,AxiMajor,FXGT OPTIMUS) | 10 million currencies | approx. $9,375 | approx. $625.00 |
| 50 lots (XM Standard,FXGT STANDARD,BigBoss Major) | 5 million currency | approx. $4,688 | approx. $312.50 |
| 30 lots (IS6FX Standard) | 3 million currency | approx. $2,813 | approx. $187.50 |
*This is an estimate based on a USD/JPY exchange rate of approximately $0.94 and a leverage of 1,000x (calculated by our editorial team). In reality, the required margin will vary depending on the maximum leverage of each company/account (AXIORY 1,000x, XM 1,000x, TitanFX 500x, etc.) and the balance restrictions. With 1,000 lots, 1 pip moves approximately $6,250, sothe maximum lot size is the number you "can" trade, not the number you "should" trade.
③ Appropriate lot size = Allowable loss ÷ Stop-loss range ÷ Value of 1 pip
The calculation for protecting your capital is not based on the upper limit, but rather"the amount you can afford to lose in a single trade." If your capital is approximately $625.00, your acceptable loss is 1% (approximately $6.25), and your stop-loss is 10 pips, then the acceptable loss per pip is approximately $6.25 ÷ 10 pips = approximately $0.63. Since 1 pip in USD/JPY is approximately $6.25 per lot,approximately $0.63 ÷ approximately $6.25 = 0.1 lotsis the appropriate lot size.
- Capital approx. $6,250, allowable 2% (approx. $125.00), stop-loss 20 pips → approx. $125.00 ÷ 20 pips ÷ approx. $6.25 =1 lot
- Capital: approx. $625.00, Allowable profit: 1% (approx. $6.25), Stop loss: 10 pips → 0.1 lot
- With 0.01 lots (1,000 units of currency), 1 pip =approximately $0.06. Even a 100-pip move against you would result in a loss of approximately $6.25.
The answer to the question "How many lots can I trade with approximately $6,250?" is not the upper limit of ① (66.66 lots at 1,000x leverage), but rather the appropriate lot size (e.g., 1 lot) in ③, which is more practical. The concept of margin before a stop-loss is explained in the section on stop-losses in overseas forex trading
Five important points to check along with the maximum lot size when making large-volume trades
When trading large-volume orders in overseas forex, simply choosing a broker with a high maximum order lot size is not enough.Here are five conditions listed on their official websites that are likely to cause bottlenecks when trading large lots.
① Split orders are limited by the number of positions and the overall account limit
Orders exceeding the limit for a single order will be split into multiple orders, but there are separateThreeTraderof 80 lots x 200 positions = 16,000 lots,FXGT STANDARD has a limit of 200 lots and 100 positions per account,IS6FXhas a limit of 30 positions (including pending orders).HFM(XM allows up to 10 accounts), you need to check the terms and conditions to see if there are any limits on the total amount across accounts. limits on the maximum number of positions and the total account holding limit . has a limit Even with brokers that allow multiple accounts, such as XMTrading and
② As your balance and transaction amount increase, your leverage decreases and the required margin increases
Leverage restrictions based on account balance and trading volume become more significant as you trade larger amounts .IS6FXoffers 500x leverage for account balances of approximately $12,500 or more,FXGT's leverage fluctuates "based on effective margin." Even with the same 100 lots, if the leverage drops from 1,000x to 200x, the required margin becomes 5 times larger (approximately $9,375 → approximately $46,875). For a list of restriction rules, while please refer to the comparison of leverage for overseas forex brokers and the precautions for high-leverage trading with overseas forex brokers
③ Some brokers lower their upper limits depending on the time zone and currency pair
Exness's official help (archived as of June 2023), the maximum lot size for Standard, Pro, Raw Spread, and Zero accounts: "7:00–20:59 (GMT+0): 200 lots / 21:00–6:59 (GMT+0): 20 lots". In Japan Standard Time, this corresponds to 200 lots from 16:00 to 5:59 the next day, and 20 lots from 6:00 to 15:59, meaning large orders placed during Tokyo hours will need to be split.Axi(Major 100/Minor 50/Exotic 20) andBigBoss(Major 50/Minor 20/Exotic 5) have different limits depending on the currency pair. Note that the "maximum XX lots" figures are often the intraday values for major currency pairs.
④ Check the execution method and slippage
Large lots are more prone to partial execution and slippage if the counterparty lacks sufficient liquidity.Vantage's PRO ECN account page states "Client orders, regardless of size (1 lot or 40 lots), are filled instantly," order books tend to be thinner during economic indicator announcements and early morning hours for any broker. Factors such as NDD (No Dealing Desk) and server location (ThreeTraderis in NY4) While are used to compare the execution capabilities of overseas forex brokers
⑤ Large-scale transactions themselves are not prohibited, but the abuse of bonuses and server overload are subject to the terms of service
No broker prohibits large-volume trading itself. However,BigBoss's official column warns that "holding too many positions can overload the server and lead to account freezing," and many brokers restrict high-risk, large-volume trading using bonuses in their terms and conditions. The relevant clauses are summarized in the sections on the causes of account freezing in overseas forex and the terms prohibiting arbitrage
Please note that overseas forex brokers are not registered with Japan's Financial Services Agency (FSA), and both the FSA and the Consumer Affairs Agency have issued warnings about trading with unregistered brokers.This article does not recommend large-volume trading or high-leverage trading, but rather summarizes the limits published by each company.

The maximum lot size can change, and some brokers do not list it on their public pages. It is best to check the official website before opening an account, and the instrument specifications in MT4/MT5 after opening an account.TitanFX's official help states, "For information on minimum trading volume and contract size, please right-click on the Quotes display in MT4/MT5 and check the 'Specifications' section," andVantage's official help also states, "You can find this information by right-clicking on a product and selecting 'specification' on your MT4/MT5 trading platform."

Frequently Asked Questions about Maximum and Minimum Lot Sizes in Overseas Forex Trading
This article answers frequently asked questions about lot size limits in overseas forex trading, based on official information (verified October 1-2, 2026)
What is the maximum lot size I can trade with overseas forex brokers?
The lot size per order ranges from 30 to 1,000 lots, and varies depending on the broker and account type.Of the 11 companies we checked,AXIORYhas a maximum of 1,000 lots per position for all accounts,FXGThas 120 lots for STANDARD 50, OPTIMUS 100, PRO 60, and ECN ZERO, XMTrading has 50 lots for Standard,HFMhas 60 lots per position,ThreeTraderhas 80 lots, andIS6FXhas 30 lots for Standard. Note that in addition to the limit per order, many brokers also have an overall account holding limit (number of positions x lots).
What is the minimum lot size for overseas forex trading?
0.01 lots (1,000 currency units) is the standard.While all 11 companies have a minimum FX trading size of 0.01 lots, accounts where 1 lot equals 1,000 currency units, such as XM Micro account (0.01 lots = 10 currency units in MT4, 0.1 lots = 100 currency units in MT5HFM CENT account (0.01 lots = 10 currency units), TitanFX Zero Micro account (0.1 microIS6FXMicro account (0.05 lots = 50 currency units), allow trading with even smaller currency volumes.
What is one lot size in overseas forex trading?
In a standard account, 1 lot equals 100,000 units of currency.AXIORYexplains in its official FAQ that "1 lot = 100,000 units of currency = 10 lots." Trading 1 lot of USDJPY results in a profit or loss of approximately $6.25 for every 1 pip (approximately $0.00) movement. As an exception, XM Micro,IS6FXMicro, TitanFX Micro, andHFM CENT use 1 lot = 1,000 units of currency, andFXGT MINI uses 1 lot = 10,000 units of currency, which differs from the 1 lot = 10,000 units of currency common in domestic FX brokers.
What happens if I trade up to the maximum lot size?
If you open an order with the maximum possible margin, the required margin and the profit/loss per pip will be very large. Ifyou open 1,000 lots of USDJPY (approx. $0.94) with 1,000x leverage, the required margin is approximately $93,750 and the profit/loss per pip is approximately $6,250. Even with 100 lots, the required margin is approximately $9,375 and the profit/loss per pip is approximately $625.00. With brokers where leverage decreases with balance or trading amount, the required margin will increase even further, and a stop-loss will be triggered if the margin maintenance ratio falls below a certain level. The maximum lot size is the "upper limit you can place," and the appropriate lot size should be determined by working backward from your acceptable loss.
What is the maximum number of open positions I can hold in overseas forex trading?
The limit varies by broker, ranging from 30 to 500, or sometimes no limit at all.The values we were able to confirm officially are:HFM500 (CENT 300), TitanFX 200 (including limit and stop orders),ThreeTrader200,FXGT100-200 depending on the account type, andIS6FX30 (including pending orders).AXIORYstates "No limit on maximum open positions," andBigBossstates "No limit on the maximum number of positions or lots that can be held." WeAxi,Exness, andVantagewere unable to confirm the limits on the public pages of XMTrading
Which overseas forex broker has the largest maximum lot size?
In terms of the maximum order size per tradeAXIORY's 1,000 lots is the highest among the 11 companies we checked.However, when looking at the entire account,AXIORYandBigBoss, which publishes a maximum of 16,000 lotsThreeTrader. Also, even if you trade with approximately $6,250 at 1,000x leverage, you can only open about 66.66 lots (USDJPY approximately $0.94), so in most cases, your own margin will reach its limit before the broker's limit.
Is the maximum lot size for XMTrading 50 or 100?
The Standard account has a maximum trading lot size of 50 lots, and the Micro account has a maximum trading lot size of 100 lots, both as stated on the official account page.However, since 1 lot in a Micro account equals 1,000 currency units, 100 lots = 100,000 currency units = equivalent to 1 lot in a Standard account. This is why other sites show both "50" and "100". The maximum trading size for the KIWAMI Extreme account and Zero account was not listed on the official account page (confirmed October 2, 2026).
How many lots can I trade in FX with approximately $6,250?
With leverage of 1,000x and USD/JPY at approximately $0.94, the upper limit is 66.66 lots, but the appropriate lot size is much smaller.The required margin for 1 lot is approximately $0.94 x 100,000 units ÷ 1,000x = approximately $93.75, so the upper limit for opening a position is approximately $6,250 ÷ approximately $93.75 = 66.66 lots (rounded down to the nearest 0.01). On the other hand, if the amount that can be lost in one trade is 2% of the capital (approximately $125.00) and the stop-loss is 20 pips, the appropriate lot size is approximately $125.00 ÷ 20 pips ÷ approximately $6.25 = 1 lot. With the maximum limit of 66 lots, approximately $6,188 is tied up in required margin, leaving approximately $62.50 available. Since a 1 pip movement corresponds to approximately $412.50, a move of less than 1 pip against the price will trigger a stop-loss level.
Summary | Check the maximum lot size using three factors: "per order," "entire account," and "conditions."
The maximum lot size for overseas forex brokersranges from 30 to 1,000 lots if you only consider the limit per order, withAXIORYhaving the highest limit of 1,000 lots among 11 brokers.However, what actually matters for large-volume trading is the overall account limit (number of positions x lots, per account) and the limits that vary depending on the currency pair, time zone, and account type.
- Order limits:AXIORY 1,000 /Exness 200 (intraday, as of 2023) /FXGT ECN ZERO 120 /FXGT OPTIMUS,AxiMajor, TitanFX 100 /ThreeTrader 80 /HFM 60 / XM Standard,FXGT STANDARD,BigBoss Major 50 /IS6FX Standard 30

Before deciding on a broker with the largest maximum lot size, consider which limit you fall into. The numbers you need tolook at will vary depending on whether you want to place a large order in one go, divide your position into multiple trades, or place orders for exotic currencies or early morning trades.
Please note that the figures in this article were confirmed on October 1-2, 2026, on each company's official website, official help page, and official column (Exness, which uses an archived official help page from June 2023).Maximum lot size and position size are subject to change without notice.Always check the latest official information and the MT4/MT5 specifications before placing an order.
