Hello Leob,I believe it's also question of trading stayle. If I want to benefit from the opening volatility I just need to catch the direction. By definition in the voltility hour if I catch the direction I will be rewarded.
I agree with this as well. If you trade the opening volatility or just volatility alone regardless of time, your probability of a fast win increases, if risk is greater than reward. Or if you simply hold the trade and exit per your eyes.
