A safe trade

After hour SSO is down to 35.30 from 36.01. I bought some at 35.30 and expect to sell in a few day in 36.00. The reason: there is no two consecutive unfilled gaps on SPY and Cobra #1 rule.

I also bot some SSO.    expect gap fill tomorrow.
Another rule is post-MDD gap fill (~70% chance to fill if gap down, ~90% chance to fill if gap up)
