I'll go out on a limb and say we have one more day lower and then we trade sideways for a while. 30 SPY $388 PUTS paid $1.08 sold for $10.50 today...definitely left money on the table but that's fine with me...that was my bottom and top
My point is we all estimate no one knows the future. Some time we are accurate and we have figured out. Trading on probability is better option for long term success.
