Hi SherpaTrader,

According to the list of supported orders, Bracket Orders are not supported at the moment. However, we can submit the opposite order once one side of the order is filled, which I've explained how to do in this thread.

Hi SherpaTrader,

Before we submit the order, we need to check that the Order Id of the OrderEvent matches the Order Id of the original order. This prevents the recursive calls to OnOrderEvent, which is the source of the error message. I've attached the backtest posted in the thread I mentioned, updated with this check.

Best,
