Send full code you are using. The reason may be invalid formula
(for example using same names for different params).
You are not saying whenever you run BACKTEST or OPTIMIZE.
Note that BACKTEST in second case will use current param values,
not the defaults.

Subject: [amibroker] ParamOptimize - different backtest results
> In the Amibroker Feedback Center is a request for an "Optimizable Param()" .
> Graham and Tomasz pointed out that this functionality already exists via the

> function ParamOptimize( TitleName, default, minv, maxv, step )
> {return Optimize( TitleName, Param( TitleName, default, minv, maxv, step ),
> minv, maxv, step );}

> As a matter of fact I had used this function before but had had problems with

> at first with using "Optimize" and performed a second backtest where I
> replaced "Optimize" with "ParamOptimize" without any other changes. The
> results of both backtests were completely different! This is true regardless
