[amibroker] Drawdown on Backtest



PureBytes Links

Trading Reference Links

I have backtested my formula for 18 months. It is all the data that I 
have. The results show a Max. trade drawdown of -11400 and a Max. 
system drawdown of -10830. However, the largest loss was 920 with the 
most consecutive losses of 3. 

When I look at the list of trades, I never had 3 consecutive losses. 
I only had 3 total losses. The total loss on these 3 losing trades 
was 1100.

I must not understand exactly what is the definition of these terms. 
Can someone explain them to me.

Here are the statistics of my backtest.
