[amibroker] System Backtest Profits Question

Trading Reference Links



Hi, I have a question about a system I am working on. The AVG. Profit
is showing up as -1.01%, the AVG loss is -20.21%, the AVG profit is
4.47%, the Win rate is 77.78%, Losers 22.22%, though the account size
grows to be huge over 10 years. 

What gives? It seems counterintuitive that the system could even be
profitable. Any ideas? 

Thanks, Eric
