Hello,
Comparative Relative Strength is calculated in AmiBroker as follows:
RS = 1000 * close / foreign( "base ticker", "C" );
So the RS is a price of selected security divided by the price of base security.
What you want to achieve is something different. You might consider using
ROC (percentage rate of change) from RS. If you want to find out
which stock outperforms index during last week you may use
5-bar ROC from RS:
outperforms = roc( relstrength("^SPC"), 5 ) > 0;
Best regards,
