The reason a copy trading stop-loss doesn't trigger is usually not "the price was hit but not executed," but rather that the position and stop-loss binding logic differ from what you expect. OKX's copy stop-loss (also called "overall loss limit") is calculated based on the total loss of the entire copy trading portfolio, not triggered by a single order's profit/loss line. Additionally, if you're using Smart Sync, some stop-loss orders may become invalid or merged due to the "position adjustment sync" mechanism.

Step 1: Confirm Which Copy Trading Mode You're Using – Stop-Loss Logic Is Completely Different
OKX has three copy trading modes, and the stop-loss execution differs significantly.
Scenario A: Spot Copy or Futures Copy (Non-Smart)
In this mode, your copied orders are managed independently, and you can set stop-loss and take-profit for each order.
However, when the trader closes a position, if the market moves violently, your stop-loss order may fail because the limit order can't be filled or the market order experiences slippage.
Completion standard: you have confirmed you're in non-Smart copy mode and understand that each copied order can have its own stop-loss and take-profit.
Scenario B: Smart Sync
This is the most misunderstood mode. Smart Sync locks your funds to a single trader, replicating positions and leverage proportionally, with all positions automatically merged for management.
In Smart Sync mode, if the trader adjusts their position (adds or reduces), the system will attempt to sync leverage and margin for the copier, which may cause your previously set stop-loss orders to be canceled or paused.
Completion standard: you have confirmed whether Smart Sync is enabled and understand that positions are calculated on a combined basis in this mode.
Step 2: Check Where the Stop-Loss Is Set – It Is Not Automatically Bound
Many people think that "setting a stop-loss will automatically follow each position," but in reality, the copy stop-loss must be manually enabled in the copy settings.
How to do it:
Open the OKX App, go to [Trade] → [Copy Trading] → [My Copy Trades].
Find the trader you follow, tap to enter [Copy Details].
Check whether the "Copy Stop-Loss" or "Overall Loss Limit" switch is turned on.
The trigger logic of the copy stop-loss is: When the cumulative loss of the follower's entire portfolio for that trader reaches the percentage you set (maximum 75%), the system automatically stops copying and closes all positions. If your stop-loss switch is not on, or if you set the ratio too high (e.g., 75%), the price may drop to a point where you feel "it should have stopped out long ago," but the system hasn't reached the threshold yet.
Completion standard: you can confirm on the copy details page that the stop-loss switch is on and the stop-loss percentage is reasonable (for example, no more than 20%-30%).
Common failure reason: Many people think "copy stop-loss" automatically attaches a stop to each order, but it is actually an overall risk control threshold. If the trader builds a position in batches, a single order's floating loss may hit your mental stop line, but if the overall portfolio loss hasn't reached the threshold, the system will not liquidate.
Step 3: Troubleshoot Common Reasons for Stop-Loss Failure
If the stop-loss switch is on but still didn't execute, check against the list below:
| Reason | Explanation |
|---|---|
| Smart Sync position merging | Under Smart Sync, copier positions are calculated on a combined basis. If the trader subsequently adjusts positions, the original stop-loss order may be canceled or paused by the system |
| Insufficient copying balance | Under Smart Sync, if the copying balance is insufficient to sync the trader's position adjustment, the system may suspend some copy functions |
| Price gap protection | If the price difference between the copier and the trader exceeds 0.5%, that copy order will be rejected by the system |
| Extreme market volatility | In extreme market conditions, users may be unable to successfully close all positions at market price due to limit price mechanisms, and the system will notify the user to manually close |
Completion standard: you can eliminate possible reasons for stop-loss failure one by one based on the table above.

Verification After Completing the Checks
After the above troubleshooting, go to [My Copy Trades] → enter that trader's [Copy Details], and confirm three things:
Whether the "Copy Stop-Loss" switch is actually on (if not, this is your chance to fix it);
What the current overall loss percentage is, and whether it has exceeded the stop-loss threshold you set;
If you are using Smart Sync, check whether positions were merged due to the trader's adjustment – if they were merged, it means the stop-loss order was reset by the syncing mechanism.
Next step: If you find that the copy stop-loss didn't execute as expected and the position has a large floating loss, it is recommended to manually close the position first. Do not continue holding a position while your expected and actual stop-loss are misaligned. After closing, re-evaluate the copy mode – if you feel you cannot consistently track the stop-loss trigger status, consider not enabling Smart Sync mode, or set independent stop-losses for each order in normal copy mode to gain more control.
