Different optimization results: AB and Metastock ?

["hmab1" <hmab@xxxx>]

Hello,

I ran the same optimization on the same system with the same 
optimizaton variables and on the same data, and I got two very 
different results between AB and MS.

The system was a simple MACD crossover with max stop loss.

Why did the results come out so different ?

In MS, I even tried both the standard MACD and the true MACD 
calculation.

Just wondering why the difference.
