If it is simple enough to lay out into a program, I would do that. I would also see what would happen if you were to backtest this strategy over the previous 3-5 years. If that happens to still show results, forward test until you feel confident. Depending on what pairs you are trading, I would add 1-5 pips of slippage on your trades to see what happens. If after all of this you are still showing profitability, stick to the strategy.
