Back test vs historical chart loading

[NickyD]

I have an indicator that prints lots of labels on a chart. This drastically slows down the back testing engine when testing large amounts of time because of the chart it builds at the end. I would like for the indicator to not print the labels during back testing, but be able to print them on the historic data when I manually open a chart. Is there a way to do this? Are there any States unique to back testing or a chart loading outside of the strategy analyzer that I can check for?

If not I guess I could check the timestamp of the bar and compare it to the current date and only print labels for the last x days...? Any other ideas?

Thanks,
Nick

Hello NickyD,

Thank you for the question.

The option with the most flexibility would be to add a bool input to the script. You could set it to default as True so you don't need to mess with it outside of the backtest, in a backtest, you could set it to false to disable drawing. This would also allow you to disable the drawings in the chart to increase performance when they are not needed.

Alternatively there is a property for backtesting:

Print(IsInStrategyAnalyzer);

You would need to use this bool from your strategy, and then change the properties of the indicator based on its value. The above statement about adding a bool input would still apply to the indicator while using IsInStrategyAnalyzer, the input would be used to control the indicator.


I look forward to being of further assistance.

A good solution. Thanks!
