Thanks Tomasz,
"Below you wrote: Score is PER SYMBOL. You need separate score for EACH
security.
So you can use individual Equity as score (taken from Equity() function)
but you can not use portfolio equity as score because it is only one."
But the Portfolio Equity is based on the price movement of the n
highest-scored stocks, not on the Equity resulting from trading the
individual stock... so the Portfolio will not reflect the additional gains
made by trading the individual stocks. I mean, a single scoring period
cannot contain several trades?
Can the PositionScore be changed dynamically, a different one for each stock
tested?
many thanks,
herman

Yes. Top "max traded" securities are traded.
If you want to exit position you have to set PositionRank to zero.

Score is PER SYMBOL. You need separate score for EACH security.
So you can use individual Equity as score (taken from Equity() function)
but you can not use portfolio equity as score because it is only one.

Yes it is possible. Just use "ValueWhen" function to hold the score for
defined period
PositionRank = ValueWhen( DayOfWeek() == 5, your_formula ); // this will
change scores only on fridays.
Hope this helps.
