Hi
@samoya, I'll answer your first post first:
1. The 3 rectangles you have don't show a cross over on the zero line from lower to upper...so I don't take those trades. However... I have seen many examples where the red dots are ABOVE the zero line in the "green area" and the red dots come all the way down and then bounce off the green zero line and switch back to white as it moves back up....those can be profitable trades as well. But currently I'm only trading the true and clear crossovers.
2. As far as length of trade, I set a sell limit for $1 over the premium purchase price, as I scalp options...not a long holder of them. So I don't wait for an exit signal...unless its swinging back quick and common sense tells me to get out. But with this logic/setup....you can almost guarantee 75 cents to a $1 premium increase.
3. I spend a great deal of time adjusting the indicator settings for one particular stock until I see positive consistency with it....then I backtest it 90 days.
4. I buy a minimum of 10 contracts consistently... the minimum delta for me is .35 cents...sometimes that's ITM and sometimes not.
Yes, this is a great setup for SPX only...but I'm now looking at AMZN as well to see how it reacts to it.
