Beware of look-ahead bias. The system probably enters a position before the actual signal is generated, which is impossible in real trading. Plus, if you do not know exactly how the strategy works, you should not trade it.
@xiaoqi7, I looked at the coding and it uses some ma. Im not specifically sure how it works, but i know the profit numbers are correct. I added commission and slippage so it would be more realistic. There are arrows pointing to where the Long and short trades were placed. I don't think that it places it before it is saying because I looked at the trades and they matched where the arrows pointed.
