Issue:
On very rare occasions, you might notice a mismatch between the PnL on WunderTrading and the exchange.
Reason:
1. If you were able to enter the trade, but for some reason your exit order failed, we will not be able to see your exit price.
2. If you entered the trade via WunderTrading but decided to exit the trade directly on the exchange, you might see a mismatched PnL due to the lack of information about your exit price.
3. When several trades are opened on the same pair and in the same direction, the exchange may combine them into one position with a shared average entry price. WunderTrading tracks each strategy separately, so its entry price may differ from the exchange’s combined average.
When one strategy closes, it can show a profit on WunderTrading while the exchange records a loss for that partial closure, because the calculations use different entry prices. This does not necessarily indicate an execution error.
Solution:
1. Avoid failed exits. Troubleshoot your failed strategies to prevent consecutive failures.
2. Do not close trades manually on the exchange. (In case of failed exits, you will still need to do so.)
3. Compare the complete exchange position history with all corresponding WunderTrading strategies, including their entry quantities, prices and partial exits. Comparing only one strategy with the exchange’s combined position can give a misleading result.
