06/23 SPY Double Diagonal *Closed*

We had this trade for over 15 trading sessions, the profit got up to 8% and when it started to drop back down I decided to close it.

I believe that for these double diagonals the timing is important. Notice on the volatility cone the orange horizontal lines, these are the pre-defined adjustment points. You can see how the 1 st. deviation on the volatility cone intersects these adjustment points in a certain time period. In my mind, this is telling me that simply by law of probabilities the trades have a high probability of requiring adjustments if you stay too long. So I didn't want to test the theory and decided to book the profits.
