Bigboss offers some of the highest leverage among overseas forex brokers. Compared to its competitor XMTrading, which offers a maximum leverage of 1,000 times, Bigboss's leverage is more than double that of XMTrading
High-leverage trading carries higher risks, but it allows you to aim for substantial profits even with a small amount of capital, making it recommended for those with limited funds or those who want to engage in high-risk, high-return trading
Bigboss's positive reviews and testimonials ②: They offer a wide range of bonus campaigns
I got a 15,000 yen bonus from Big Boss, but it

all disappeared in two days.
Now

For USD/JPY, the spread on a standard account is on par with XM's KIWAMI account.

#BigBoss #fx #BigBossgacha
Bigboss introduced a points system , where you can accumulate BigBoss Points by continuing to trade.
These BigBoss points can be converted into cash, but you can also use 100 BigBoss points to spin a gacha with no losing spins, where you can win up to 5,000 USD worth of credits
You can earn a maximum of 16 BigBoss points per lot trade, but there is no upper limit, and points are accumulated even for trades less than one lot, so even those who mainly trade in small lots can earn BigBoss points
Bigboss's positive reviews and testimonials #5: Access to its proprietary trading app
MT5 exclusive: I tried out the official BigBoss app!

"BigBoss QuickOrder" https://t.co/c0E32Rt2kP
The $50 (6,503 yen) bonus I received from the new trader campaign was properly reflected. I
usually trade on my PC, but I installed the app on my smartphone just in case. #fx #BigBoss #mt5 pic.twitter.com/0PTMFBHOnR
Bigboss offers an official trading app called BigBoss QuickOrder (BBQ)
BBQ known for its simple interface and intuitive operation .
It also includes a free analysis tool, and although there were system problems in the past due to excessive user numbers, these have now been resolved
Bigboss's positive reviews and testimonials #6: Excellent Japanese language support
I opened a new account with Bigboss.
— Miyamoto (@miuti0123) March 1, 2025
The spreads are wide, but their Japanese support is excellent, and the emails they send give off a strong sense of "they must have had a hard time with complainers in the past,"
which makes me feel quite sympathetic. That being said, the spreads on Bitcoin are narrow, so I think it's a good option for trading.
Bigboss provides support for inquiries in Japanese
Because they have Japanese staff, you can expect responses in native Japanese, and they are known for their courteous service
You'll likely have many questions, especially when you first start using the service, but if the support is solid, you can rest assured that your issues will be resolved through inquiries
Bigboss's positive reviews and testimonials #7: Supports copy trading
\Ready!/
— Tengen@ team ALB (@protrader11011) June 6, 2025
BigBoss's MASS Copy Trading is finally restarting
! It's a tool that lets you copy my trades exactly.
And... I've already followed it with my real money
! Because we're doing this together, we're going to be serious.
I recommend starting with a small amount (10,000-30,000 yen).
I myself am doing this as a small-amount challenge... pic.twitter.com/E82CKjkMdr
Bigboss supports copy trading
Copy trading is a system that copies the trades of professional traders and applies them to your own account. By paying a fee, you can replicate professional methods, making it a popular system for beginners who can't read charts and part-time traders who don't have time to trade themselves
You can search for traders to copy using the filter search function, so you can find traders that suit your investment style
Bad reviews and comments about Bigboss
Here, we'll introduce some negative reviews and comments about Bigboss
- Bigboss's negative reviews and comments ① High transaction fees
- Bigboss's negative reviews and comments #2: Spreads are generally wide
- Bigboss's bad reputation/reviews #3: There are rumors of withdrawal refusals
Bigboss's negative reviews and comments ① High transaction fees
Bigboss's fees are so high
— Off (@off19487) August 1, 2024
At Bigboss, there are no trading fees for FX trading in the Standard account, but trading fees are charged in the Pro Spread account and Deluxe account. In the Pro Spread account, a trading fee of 9 USD (equivalent) is charged per round trip lot
While it's understandable that trading fees are incurred with a low-spread account, they are somewhat higher
Additionally, for cryptocurrency CFDs, a short-term settlement fee of 0.4% round trip is charged for trades with a holding period of 5 minutes or less

Bigboss's negative reviews and comments #2: Spreads are generally wide
I opened a new account with Bigboss.
— Miyamoto (@miuti0123) March 1, 2025
The spreads are wide, but their Japanese support is excellent, and the emails they send give off a strong sense of "they must have had a hard time with complainers in the past,"
which makes me feel quite sympathetic. That being said, the spreads on Bitcoin are narrow, so I think it's a good option for trading.
Bigboss's spreads are set slightly wider compared to its competitors
Therefore, it is not particularly suitable for those who primarily engage in short-term trading such as scalping
However, for some currencies, such as Bitcoin, the spread may be narrower than other companies
Bigboss's bad reputation/reviews #3: There are rumors of withdrawal refusals
I found several posts from users who were denied withdrawals when trying to withdraw funds from Bigboss
However, it is highly unlikely that this can be considered a malicious refusal to withdraw funds, and we were able to find posts that clearly stated the reasons
You can find a detailed explanation of Bigboss's withdrawal refusal here
What are the safety and reliability requirements for Bigboss?
| Operating company | Big Boss Holdings Company Limited |
| Year of establishment | 2013 |
| Home ground | Seychelles |
| address | Vistra Corporate Services Centre, Suite 23, 1st Floor, Eden Plaza, Eden Island, Mahe, Seychelles |
| Financial License | Financial License for Saint Vincent and the Grenadines ( SVGIBC ) |
| Maximum leverage | 2,222 times |
| Fund management method | Separate management |
| Japanese support | can be |
| Margin call | None (Zero-cut system is used) |
Bigboss is an overseas forex broker founded in 2013
Our services for the Japanese market started in 2016, giving us approximately 10 years of operational experience
The maximum leverage is 2,222 times, which is among the highest for overseas forex brokers
Funds are managed through segregated accounts, and the company holds SVGIBC
We also offer Japanese language support, and you can contact us via email
Customer support hours are Monday through Friday, from 10:00 AM to 1:00 AM Japan time
If you are considering using these services, be sure to check the overall ratings in recommended overseas forex broker comparison ranking
What financial licenses does Bigboss hold?
Bigboss holds SVGIBC
SVGIBC publishes the financial institutions it registers with on its official website, but it does not issue financial licenses for FX brokers and therefore does not guarantee that it is actually an FX broker
Therefore, it is considered to have low credibility among financial licenses
However, since there are overseas forex brokers that do not hold any financial licenses, Bigboss, which does hold a financial license, can be said to have a certain level of reliability
How does Bigboss manage its funds?
At Bigboss, we keep customer funds in separate accounts
Segregated accounts refer to a method of storing Bigboss's operating assets separately from customer funds, and are adopted by many overseas forex brokers
Because we manage our operating assets and customer funds separately, even if Bigboss were to face operational difficulties, there is a high probability that your deposited funds would be returned
However, since this is not a trust-protected transaction, it is important to note that a 100% refund is not guaranteed
What is the Bigboss Loyalty Program?
Bigboss has a loyalty program where you can move up in rank based on the number of days you trade
Bigboss points are accumulated according to the number of trading lots, but the higher your rank, the more Bigboss points you earn per lot, and the higher your leverage reduction rate will be
Other than ProSpread accounts
| rank | BBP earned per lot | Leverage easing rate | Rank-up conditions | Turn into cash |
|---|---|---|---|---|
| Executive | 16 BBP | none | Open an account | Not possible |
| Advanced | 21 BBP | 1% | Continuous trading for 25 days or more, or 3BBC | Not possible |
| Expert | 26 BBP | 3% | Continuous trading for 55 days or more, or 50 BBC | Possible |
| Prime Elite | 32 BBP | 5% | Continuous trading for 95 days or more, or 200 BBC | Possible |
| Deal Master | 33 BBP | 10% | Continuous trading for 150 days or more, or 500 BBC | Possible |
ProSpread Account
| rank | BBP earned per lot | Leverage easing rate | Rank-up conditions | Turn into cash |
|---|---|---|---|---|
| Executive | 6 BBP | none | Open an account | Not possible |
| Advanced | 8 BBP | 1% | Continuous trading for 25 days or more, or 3BBC | Not possible |
| Expert | 11 BBP | 3% | Continuous trading for 55 days or more, or 50 BBC | Possible |
| Prime Elite | 18 BBP | 5% | Continuous trading for 95 days or more, or 200 BBC | Possible |
| Deal Master | 19 BBP | 10% | Continuous trading for 150 days or more, or 500 BBC | Possible |
What actions and transactions are prohibited in Bigboss?
Bigboss prohibits the following actions, and violations may result in measures such as the cancellation of profits or the freezing of accounts
- Transferring or lending a Bigboss account to a third party
- Lending your account name to a third party
- Extremely high-frequency trading that impairs the server's execution capacity
- Multiple account logins from the same IP address
- High-risk hedging transactions using multiple accounts
- Trading that targets only times when the market is highly volatile, such as when important economic indicators are released
- Excessively risky trading that exploits loopholes in bonuses and zero-cut systems
- Transactions that Bigboss deems to lack fairness
Bigboss primarily prohibits transactions that place an extreme load on the servers and transactions that are highly speculative
One point to note is point ④, which prohibits logging into multiple accounts from the same IP address
Even if the logins are made by different people, if multiple accounts are logged in from the same IP address, it will be considered lending your account name to a third party and will violate the prohibited activities
To avoid problems, please refrain from using the service on devices where third parties may log in, such as shared PCs
You can find Bigboss's latest guidelines here
What are the leverage restrictions at Bigboss?
At Bigboss, apply to depending on the margin balance
The following balances are subject to leverage restrictions:
| Margin balance | Maximum leverage |
|---|---|
| 0USD (equivalent) ~ 19,999USD (equivalent) | 1111 times |
| 20,000USD (equivalent) ~ 49,999USD (equivalent) | 555 times |
| 50,000USD (equivalent) ~ 99,999USD (equivalent) | 200 times |
| 100,000USD (equivalent) or more | 100 times |
To trade with a maximum leverage of 1,111 times, you must keep your margin balance below 20,000 USD (equivalent)
Leverage restrictions are updated at 6:00 AM during daylight saving time and 7:00 AM during standard time, so be sure to adjust your margin balance before then
Are there any instances of Bigboss refusing withdrawals?
Upon investigating Bigboss's withdrawal refusals, primarily through social media, we found multiple posts regarding withdrawal refusals
I was refused a withdrawal from Big Boss.
— @jap (@ma_tjjk1999) March 2, 2023
100,000 → 250,000
, without using any bonus.
Those considering using Big Boss should be careful. pic.twitter.com/0RhiLi8PIf
In this case, the withdrawal was refused on the grounds that the transaction was suspicious and violated the guidelines
of the actions prohibited in Bigboss here , and it is highly likely that you have violated these prohibited actions.
Bigboss prohibits logging in with multiple accounts from the same IP address, as this is considered lending your account name to a third party. However, it seems that many users who use Bigboss on shared devices are unknowingly violating this rule
Ding! I received an email from BigBoss about a compliance violation.
— MARINA@Uber Tokyo (@monogoibaa) August 16, 2024
It looks like my account has already been deleted, and I can't even log in or see my MT4 information
. This isn't a withdrawal refusal... It looks like I'll lose not only yesterday's profits, but all the assets in my account
as well. It was a high-risk trade targeting times of high market volatility, such as during economic indicator announcements... pic.twitter.com/rQTbt5zhWD
In this case, it appears that the guidelines were violated because the trader was only engaging in highly liquid, high-risk transactions, such as those conducted during the release of important economic indicators
The person in question seems aware of their violation of the rules and appears to accept the situation
there were many secondhand posts, such as those below, claiming that withdrawals were being refused
Rumors are circulating that BIGBOSS is refusing withdrawals, canceling profits, and even refusing to return the principal amount
— KM (@ry0521) December 26, 2023
It seems like BIGBOSS is experiencing a lot of withdrawal rejections
— taka@Retired Investor (@taka94879114) June 27, 2024
Because there were few posts with actual evidence of withdrawal refusals, it's possible that only rumors spread that withdrawals had been denied
We were unable to confirm any
With overseas forex trading, withdrawal refusals can occur for various reasons, so it's a good idea to check in advance the causes and solutions for withdrawal refusals , as well as the causes and solutions for account freezes
Who is Bigboss recommended for?
Here, we'll introduce who Bigboss is recommended for and who it's not recommended for
Bigboss is recommended for people who: ① want the benefits of long-term use
Bigboss has a loyalty program where you can move up in rank based on the number of days you trade
There are five ranks, starting from Executive and ending at Deal Master. The higher your rank, the more BBP you earn per transaction
BBP can be converted into credits, or used to spin a gacha where you can win up to 5,000 USD (equivalent) worth of credits , allowing you to acquire credits that can be used for trading.
You can find more details about our loyalty program here
Bigboss is recommended for people like this (2) those who want to trade with high leverage
Bigboss offers a maximum leverage of 2,222 times, which among the highest levels offered by overseas forex brokers .
While there are conditions for trading with maximum leverage, Bigboss allows you to expect significant profits even with a small amount of capital by utilizing high leverage
Leverage of 2,222x is available with a Deluxe account, so if you want to trade with the maximum leverage, open a Deluxe account
Bigboss is recommended for people like this ③: those who want to use a customizable account
Bigboss offers a customizable account type
With a Deluxe account, you can increase your leverage multiplier and trading fee cashback rate by equipping items
We plan to add more items in the future, so you can customize your account to suit your own style
You can find more detailed information about Bigboss items here
Bigboss is not recommended for the following people: ① Those who primarily engage in scalping
Bigboss's spreads are set wider compared to its competitors
Therefore, not suitable for short-term trading such as scalping .
Furthermore, there are other factors that make it unsuitable for scalping, such as the fact that BBP cannot be earned for trades with a position holding time of less than 10 minutes
Those interested in scalping should also check out scalping tips and recommended accounts
What I learned from actually using Bigboss
Here, I'll share the advantages and disadvantages I discovered after actually using Bigboss
Benefits I discovered after actually using it
Bigboss QuickOrder is easy to use and high-performance
Bigboss QuickOrder is a trading app provided by Bigboss
The interface is simple and easy to understand, and features that support trading, such as push notifications when a specified rate is reached and the ability to close multiple positions at once, are user-friendly and well-received
Additionally, some TradingView features are available, allowing for chart analysis
High execution power
Bigboss focuses on strengthening its servers and employs the NDD (No Dealing Desk) order execution method, resulting in high transaction transparency and extremely high execution speed
Therefore, slippage is less likely to occur, and even in short-term trades, execution is quick, allowing for smooth and efficient trading
Disadvantages I discovered after actually using it
There is a compensation process from another account
Bigboss employs a zero-cut system, so unless there is fraudulent trading, even if your balance goes into the negative, you will not be required to make additional margin calls, and it will automatically return to zero
However, if you have multiple accounts and have balances, any negative balance will be covered by the balances in other accounts. *Excluding Deluxe accounts
If you only have one account, or if there are no balances in any other accounts, a zero-cut will be applied, and Bigboss will cover the negative balance. However, if you have balances in other accounts, you will be responsible for the negative balance, and if the balance in your other accounts is not enough to cover the negative balance, Bigboss will cover the remaining amount
As explained above, if you have balances in multiple accounts, please note that funds will be transferred from other accounts before the zero-cut occurs
The spread tends to widen
Bigboss tends to have wider spreads compared to other companies when market liquidity increases
Trading with a wide spread is disadvantageous for traders, so when the spread is wide, trading opportunities are lost
This can be considered a disadvantage for traders
