Here is the secret:
1. Wait an hour after US market open
2. Flip a coin
3. Heads go long/Tails go short
That is only the first half of the secret. The 2nd part is close the trade after the next chart bar if the position is in a loss. It it is in a profit close at the end of the 3rd bar. It makes no difference what time frame you are trading. Wait 2 bars and repeat. Try it. It will keep you from losing your bankroll.
