Same idea in my mind but really hard to guess which day to try to go 1-sided trend. I'll just try to speculate the expiry day by entering positions at end of 2nd last trading day.
BTW, IV has incr ...
I just have more confidence on tomorrow (guess to be an up day), targetting 19900.
So considering this 以小博大.
Although IV is incr, the up trend forms better, so I will still try if this afternoon drop to 19450 around.
