The name "Smart Arbitrage" on OKX actually refers to two different things: one is an automated rebalancing portfolio under Strategy Trading, and the other is a BTC Savings product available only to VIP users. The "rebalancing and exit costs" mentioned in the title refer to the first one. After a strategy is created, the funds invested are isolated from your trading account. There is no extra fee when you exit, but the coins and prices you get back at the moment of exit depend on the current real-time market value of the strategy's holdings, not the USDT amount you originally put in.

What Smart Arbitrage Actually Does
It solves a very specific problem: you are bullish on several coins at the same time, but you do not want to manually adjust your portfolio. The principle is to set a target allocation (for example, BTC 50%, ETH 30%, SOL 20%), and the system continuously monitors the actual ratios. When one coin rises too much and its share exceeds the target, the system automatically sells a little. When another coin falls too much and its share is too low, the system automatically buys more. The whole process is an automated version of "buy low, sell high." The trigger for rebalancing is based on ratio deviation, not on predicting price movements.
You can select up to 10 coins, and currently only USDT-quoted trading pairs are supported. The USDT you invest when creating the strategy will be converted by the smart trading system into the coins in your portfolio. The funds are isolated from your trading account and run independently within the strategy. This is important to note: the money in the strategy no longer counts toward your available balance in the trading account. If you have other positions at the same time, your margin ratio will be affected.
Two Trigger Methods for Rebalancing
When setting up the strategy, choose one rebalancing mode:
Ratio Rebalancing: Set a deviation threshold (for example, 10%). The system checks the actual ratio of each coin every 5 minutes. As soon as one coin's deviation exceeds the threshold, a rebalance is triggered. This is suitable for volatile markets where you want to capture rotation quickly, but rebalancing will happen more often.
Scheduled Rebalancing: Set a time interval (for example, 4 hours). The system only checks once when the time is up. The official documentation also mentions that scheduled rebalancing only executes if the deviation ratio exceeds 3%. This means if you set it to check every 1 hour, but a coin's ratio only deviates by 2%, the system will keep waiting until a check finds a deviation above 3%.
My take: If the coins you hold have very different volatility (for example, one major coin plus one meme coin), Ratio Rebalancing is more suitable because deviations accumulate quickly. Scheduled Rebalancing might wait too long to trigger and miss the window. If your portfolio consists of low-volatility major coins, Scheduled Rebalancing is more convenient and reduces unnecessary frequent trading.
How to Create a Strategy
You can do this on both Web and App. Go to the Trade page and switch to Strategy Trading mode (top left on Web, top right on App). Select Smart Arbitrage from the strategy list. Then fill in the coin allocation, target ratios, rebalancing mode, and investment amount.
If you do not want to configure it yourself, OKX later launched a Smart Portfolio feature that provides preset TOP10 blue-chip coin portfolios and TOP5 MEME coin portfolios. You just enter an amount and create it with one click. This is suitable for people who have not decided on an allocation yet and want to try it out first.
Exit Costs: No Fees, But There Are "Hidden Costs"
Exiting Smart Arbitrage does not charge a strategy management fee or redemption fee. When you click to stop the strategy, the system will sell the current holdings at market price and convert them into USDT (or your chosen settlement method), then return them to your trading account. The cost generated in this process is the trading fee, which is the same as your usual spot trading fee, calculated based on your VIP level.
But what you really need to check when exiting is "how much comes back." You invested USDT, but during the strategy's operation, coin prices fluctuate. If you exit after a coin has risen significantly, the overall portfolio value may be higher than what you invested. If you exit during a decline, you may lose money. The exit price is the market price at the moment you operate, not the price when the strategy was created, and not any "guaranteed principal" price.
Another easily overlooked point: after a strategy is created, funds are isolated from your trading account. During operation, they no longer count toward your trading account margin. If you also have futures or other leveraged positions, the isolated strategy funds may lower your margin ratio and in extreme cases trigger liquidation. This is a common reminder for strategy trading products, and it is also mentioned in the official documentation.
Difference from BTC Savings
The name "Smart Arbitrage" in the title can easily be confused with another product: BTC Savings. This is a BTC wealth management product on OKX for VIP 1 and above users. The minimum subscription is 0.01 BTC, the historical annualized return is 1%–3%, and there are no fees for subscription or redemption.
Its redemption rules are completely different from the strategy-based Smart Arbitrage: if you apply before 15:00 (UTC+8), it arrives at 16:00 on the same day. If you apply after 15:00, it arrives at 16:00 the next day. In extreme cases, it may take up to 7 days. No yield is generated during the redemption period, and once subscribed, it cannot be canceled. You can only exit through redemption.
If the "Smart Arbitrage" you heard about from a friend is recommended for "earning stable BTC interest," it is most likely the latter. Do not mix up the exit logic of these two products.

What to Check When Stopping a Strategy
After clicking stop on the strategy page, do not just look at the "Stopped" status. Check two things: the USDT amount credited to your account, and the sell details in your transaction history. The details will show the price and quantity of each coin sold. You can use this data to verify whether the actual fee rate at exit matches your expectations. If you find that a coin's sell price deviates significantly from the market price, first check whether it was a market order that triggered high slippage under extreme market conditions, rather than repeatedly stopping and restarting the strategy.
