QUANTCONNECT COMMUNITY
Hello QuantConnect team!
I have an issue with the OnEndOfAlgorithm method. It often executes before my system finishes trading, which creates errors when crucial variables are not yet assigned.
What is going on? And how can I make a function that will always execute at the end of my algorithm?
Thanks!

The
OnEndOfAlgorithmmethod is an event handler that is triggered when your algorithm has finished executing as its final step. This is typically used for performing final analysis or saving the state of your algorithm. If it's executing before your system finishes trading, it might be because your trading operations are not fully completed or are running asynchronously.Here is an example of how you can use the
OnEndOfAlgorithmmethod in Python:This method is called at the end of a backtest or live trading operation and is intended for closing out logs. It does not require any argument input and does not provide a return.
If you want to ensure that certain operations are completed before the end of your algorithm, you might want to consider structuring your code such that these operations are completed within the main trading loop or within other event handlers like
OnData.For more information, you can refer to the QuantConnect documentation on event handlers.
