[amibroker] Re: Drawdown on Backtest

I believe (but am not 100% sure) that "consecutive trades" are 
determined by the trade exit date, not the entry date.  Are you sure 
that your 3 losing trades were not consecutive?  It appears from the 
report that the losing short trade and the two losing long trades 
were consecutive.  How many positions did you have open at one time?

Since your system had a 96% drawdown, I would not be surprised that 
your 3 losing trades were not consecutive.  Due to the compounding 
nature of your system, it might be better to look at percentage 
losses instead of dollar or point losses.  Your average loss was 275% 
and one trade lost 465%.  The fact that you achieved this with only 
0.2% exposure on the long side suggests that you are using leverage 
that is beyond my comprehension.
