Sorry to take so long to reply. The last couple of years have been a good time to do this. Other years will suck, I'm sure. The trades are not totally neutral in that my target is not where the market is now, but where I think it will be when the options expire. So if I put on a fly, the center strike is slightly above the current price in this bull market. I only use liquid stock indexes. I do not trade if the UL is below its 4-wk MA. This keeps me out at times. For example, I was not trading for most of April, August, and November of 2017. Finally, some of the trades are not neutral, they are bull put spreads, and these I will only trade in a secular bull market. However, the neutral trades have been a bit more profitable. I try to get in on a down day with higher IV. I don't do adjustments, but I will get out of a trade if it makes me over half the premium in a few days.
