[amibroker] Re: Custom backtester ignores my include file

["gp_sydney" <gp.investment@xxxxxxxxx>]

I don't have this problem when I try it. The included variable works
fine across the custom backtest code.

However, there are a few problems with the custom backtest code you've
shown here. Firstly there's no actual backtest performed, and secondly
you can't write to the Trade object's "Shares" property as it's
read-only (although the help doesn't actually tell you that).

By including the PreProcess method you've indicated you're going to
use the mid-level (or low-level) interface, in which case you need a
matching PostProcess method call and a call to ProcessTradeSignals at
each bar. If you only want to use the high-level interface, replace
the PreProcess method with the Backtest method.

Regards,
GP
