Stop strategy executing historical data

[soulfx]

Correct. When you enable the strategy it will process the historical data just like a back test up the most recent bar. If there is a left open position when it hits the last bar this will cause the strategy to be a yellow state on the Strategies Tab, meaning it is waiting to be flat state before processing live.
Using if(Historical) return; will stop the strategy from processing historical data and only focus on the live data.

So if the history was included and the strategy opened/submitted an order just before the first live bar - it would wait (in yellow state) for this to close with live data before starting the strategy setting to Green state and beginning the Performance.Realtime calculations for this strategy run?

You are correct here as well. This will allow you to determine the prior performance and if the performance is good enough to continue trading or to stop.

Let me know if I can be of further assistance.

thank you
