Frankly I never liked ICs though I did have a journal here recently where I was trading them. I eventually gave them up and am working on high reward:risk directional trades instead.
To answer your question, you can have a look at the rules in my journal. In a nutshell, I rolled out whichever side was "threatened". I determined this with delta. I'd start with the short options at around delta=7. If either short option's delta went to 20 for calls or 25 for puts I'd roll out. Keep in mind I was doing these ICs on NDX and RUT both indexes. ICs on individual stocks are way more susceptible to adverse gap moves.

spot delta is zero
Spot gamma is low
But as stock moves, spot gamma goes up. So you can't hedge it because the next dollar up has much more impact than if spot moves one dollar down.
it depends on the pricing but definitely the short call
Quote from nixodian:
"But you can't hedge a position where the second order Greeks aren't stable" ie when spot delta is zero, and spot gamma is low.
can you elaborate? since when is spot delta zero and gamma low in relative terms?
do you like using ICs / credit spreads in general?
Quote from nixodian:
what do you mean by "second order Greeks aren't stable"?
so if your book overall was looking shakey and the call side had doubled in premium the put side halved. just close the call side or whole thing or nothing?

ICs suck when they go against you, sure everyone agrees! adjustments adjustments adjustments, when? how? why?
what high reward:risk directional trades you chosen? l had too many naked writes, credit spreads go against me that l have chosen debit trades instead like calendar, a better long term prospect, with credit spreads bringing in spare change.
deltas at 7 is a little far OTM for me, you would be taking on high risk : reward for that, a delta shift of 0.13 sounds reasonable to me. but is there a broker that allows you to set stops / trades at 0.13 delta change? and is there a way of calculating what the premium would be at a 0.13 delta shift?
btw do / did you use IB on index options?
