Avoid securities starting with ~ in backtest

[thankyou18]

During backtest, some securities with names starting with ~ are causing distortion in the backtest results. How can I run the backtest and exclude securities with names starting with ~ in the test?

Thank you.

Exclude composite symbols from backtest

While doing backtesting, some composite symbols with symbol names starting with ~ are distorting the results. How can I exclude composite symbols from backtest? Composite symbols start with ~. Thank you. EDIT: I think I've found the solution. I can use Name() to get the symbol name, then work from there.

You can save analysis to APX file so analysis settings and AFL are stored in such file.

Alternatively to analysis settings you may check for Group() membership via AFL also.

if ( GroupID() != 253) {

    // then do something
}
