Farward Testing versus Backtesting

The PROphet EA nailed a huge trade this week. For comparison I ran the same week on the backtester in MT4. To my surprise, the backtester didn't place any trades this week so far even though the EA actually did place atrade on a farward testing Demo Account. No matter how much you backtest, 90% is the most accuracy available. And nothing beats a farward test on a live account with real money.
