It’s not an error. It’s a warning.

OrderSend “should” be check on boolean basis

Example:

bool ticket = OrderSend(...);

[Marco vd Heijden]

You didn't check the return value of OrderSend()

Please see: https://www.mql5.com/en/docs/trading/ordersend

OrderSend

The OrderSend() function is used for executing trade operations by sending requests to a trade server.

bool  OrderSend(     MqlTradeRequest&  request,      // query structure     MqlTradeResult&   result        // structure of the answer     );

Parameters

request

[in]  Pointer to a structure of MqlTradeRequest type describing the trade activity of the client.

result

[in,out]  Pointer to a structure of MqlTradeResult type describing the result of trade operation in case of a successful completion (if true is returned).

Return Value

In case of a successful basic check of structures (index checking) returns true. However, this is not a sign of successful execution of a trade operation. For a more detailed description of the function execution result, analyze the fields of result structure.
