[amibroker] Foreign-S&P500 trend-code question

["srengret" <lechols@xxxxxxxxxxxxxx>]

I'm trying to code buy selection criteria that requires the S&P500
index ("^GSPC") to be higher now than 20 days ago along with a
RelStrength measure.
Here's the section of code of interest:

Buy = RelStrength("^GSPC") > 20.0
AND Foreign("^GSPC", "Close") > Foreign ("^GSPC", "Ref(Close,-20)");

When I place this in previously working code with other criteria, it
doesn't seem to have an effect.

Does anyone see what is wrong with the last line and/or is there a
better way to do this?

Regards,
SrEngRet
