Good to know indexes work for you. Care to give details? For me managing (rolling, repairing) iron condors in SPX were almost killed by commissions. Doing three repairs in a row would barely put me in the plus after commissions. And I use Interactive Brokers, cost can't get much lower I guess.
I only trade the ES futures options these days, and with the VIX where it is and the skittish mode we're in - pretty much a week or less. I'm looking to put on some Monday expiry spreads this afternoon.
You need enough potential in the initial setup to overcome any adjustment hits. The biggest problems I've had over the years were too much exposure and too much time left on my positions. There was a time where I feared where the market would go and I could get run over - and I did get run over. In the current environment, you should have a setup that will benefit a good bit from more of these sudden shocking moves.
