Amibroker position size optimization

[Gunslinger]

Hi guys,
I'm trying to run an optimization on position size in Amibroker and the first run (iteration x of y) it spits out values but all subsequent attempts yield nothing.
I think it's becuase I'm using

uCurrentEquity = Foreign("~~~EQUITY", "C");

in my buy signal tests.
If I change this ignore equity and just set a straight position size it works fine so I think it might be resetting equity to zero at the end of the first run but I don't know for sure and don't know how to test.
I'll email Amibroker support tomorrow but they're closed ATM I guess so I'll try here first and reply back with the solution if no-one replies first.

Cheers,
JB

According to Amibroker support (who are great) the correct way is either by setting position size as a % of equity or you can get equity by using a custom backtest procedure http://www.amibroker.com/guide/a_custombacktest.html

Sorry about the lateness if anyone was waiting for a reply on this.

Cheers,
