Recalculate volume on multiple instruments
04 Apr 2022, 14:37

I have a bot that places pending orders using _hlbars_BarOpened(BarOpenedEventArgs obj). Using this, on every bar open the volume to be used in the next pending order is recalculated based on the new account balance.

This method works well. However, I began forward testing the bot on multiple instruments and realized that I need volume to be updated every time the account balance is updated.

For example, if I run two instances (one on EURUSD, one on GBPUSD), starting with $1,000 in the account, and win $50 on EURUSD, the existing Pending Order on GBPUSD will need to be updated immediately to reflect volume based on $1,050.

Any advice would be appreciated, thanks.

Hi,

The account balance is updated when you close a position, or you deposit/withdraw funds, for later two there is no way to know that but for position close you can use the Positions Closed event.

So what you need to do is first subscribe to Positions.Closed event and then move your calculation logic to Positions closed event handler.

Hi,

Thanks for your response. I am, however, unfamiliar with Positions.Closed events. Do you maybe have a code sample so I can see where and how to place the calculation logic?

Thanks for the inclusion of the API reference.

The updated code looks to be running correctly, thanks.
