[amibroker] Re: Accessing the current "Buy/Short" value during backtesting??

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

What exactly are you trying to achieve? Are Value1 and Value2
constants or arrays? Is ProfitFactor supposed to be constant during
the backtest based on some particular bar's buy/short values, or
should it also be an array that potentially changes every bar?

>From what you're asking in your first paragraph, you'd have something
like:

action1 = Buy && !Short;
action2 = !Buy && Short;

Here action1 and action2 are both arrays. What are you then wanting to
do with those results?

Regards,
GP
