[amibroker] Re: Simple coding question...

["longarm61" <norm1@xxxxxxxxxxx>]

Thank you very much, Mike. I was close, but the negative values threw 
me off.  I had it like so:

Offset = Optimize("Offset", -.10, -.10, -.25, .05);
Buy = Close <= MA(Close, Periods) Offset;

Apparently AB doesn't like it that way.  ;-) 

Thanks again,

Grant
