[amibroker] Re: How to use AddCustomMetric() to add external values

["Steve Davis" <_sdavis@xxxxxxxxx>]

Herman,

As Mike mentioned, the price arrays are not available in the custom
backtester. One of the challenges of using the CBT is how to get data
into it. There are multiple ways to make the data available:

* Foreign
* PositionScore
* PositionSize
* StaticVar

The PositionScore and PositionSize arrays are accessed differently
in the CBT. They are available at each bar as properties of the
signal object. For example:

lastBar = BarCount-1;
sig = bo.GetFirstSignal(lastBar);
ticker = sig.Symbol;
number1 = sig.PosSize; // PositionSize at this bar
number2 = sig.PosScore; // PositionScore at this bar

I have not tried using StaticVars in the CBT, but I expect it will
work for your purpose, since I believe you do not need an array.

Hope this helps,
Steve
