Not much to add over and above what has already been said.
Cottle's treatment of gamma scalping is as good as it gets IIRC.
Here's some more information, largely extolling the virtues of haircut with ulterior motive

, but valid nonetheless:

If you are not able to follow Cottle then this won't be much better :eek:
Persevere. You can't read Cottle as you would read a fiction novel and expect it to go in (Stating obvious? Sorry

)
If/when Cottle does another version, he may offer the opportunity for feedback on the draft as he did with his latest version. You might want to take that opportunity based on your experiences so far.
IV_Trader appears to be a big fan of gamma scalping at the moment AFAIK: Playing straddles on volatility build-ups prior to reports in an attempt to have IV gains as report approaches offset/mitigate any decay; gamma scalping all the while as a bonus on top....or vice versa. He appears to have a solid methodology for selecting appropriate issues to execute this strategy with....he might share his secret sauce if you ask nicely
Given this is probably OT for this thread (is that possible?), suggest start a new thread in the
Options Forum to get access to a wider range of expertise.
Good luck.
