Subject: [amibroker] Foreign-S&P500 trend-code question
>
> 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?
