I don't know if it is proper to ask here. We post some logs to track the status of the algorithm. But we found sometime the log is not posted even if the QCAlgorithm.Log is called. Since Log method is a public method, we have an extended method to QCAlgorithm to handle limit order calculation and call Log method to output the information of the order in this extended method. All the messages from this extended method cannot show in the log window. Does anybody know why? Thank you very much.
