Filter for rotational system

[djjazzy213]

For a rotational system, I am trying to filter out or exclude certain stocks with a Close < 10 or RSI(14) > 60

The positionscore is based on a different indicator.

Does "Filter" work here or is that only for exploration?
i.e. Filter = Close < 10;

Would this require a custom back test?

thanks in advance,

@djjazzy213 Filter is a Reserved Variable. Probably best to not use it as a user created variable in your formula. You can incorporate the ideas you have while building your PositionScore. An example might be something like this,

Score = ... // your forumula for creating a ranking
PositionScore = IIf(C > 10 OR RSI(14) > 60, 0, Score);

Technically there is not a problem in using Filter in backtest (or elsewhere) and doing this:

SetBacktestMode(backtestRotational);
SetPositionSize(1, spsPercentOfEquity);

Score = 100-RSI();
Filter = C > 10 OR RSI(14) > 60;
PositionScore = IIf(Filter, 0, Score);

Upper code would have same outcome as this code:

SetBacktestMode(backtestRotational);
SetPositionSize(1, spsPercentOfEquity);

Score = 100-RSI();
MyFilter = C > 10 OR RSI(14) > 60;
PositionScore = IIf(MyFilter, 0, Score);

Filter would function like any other user variable. It will not filter (in backtest) but will just store array in upper example.

Only in Exploration Filter would have additional/main function of... well, filtering result output. It is essential part there.
