Looking for trends with PSAR and ADX

Any currency pair and timeframe can be used in this system. Two indicators: Parabolic SAR with default settings (0.02, 0.2) and ADX 50 (with +DI, -DI lines). Rules are: 1. LONG when the +DI line is above the –DI line, and Parabolic SAR gives buy signal (below price). When +DI line is below the –DI line, no Parabolic SAR buy signals should be taken. 2. SHORT when the -DI line is above the +DI line, and Parabolic SAR gives sell signal (above price). When -DI line is below the +DI line, no Parabolic SAR sell signals should be taken. 3. Exit when the two DI lines cross again (reversal).
