Quote from atticus:
He's right. The adjustments are either deferring the loss or the adjustment becomes a larger risk than the original trade it supplants. If in doubt, get out. It has nothing to do with comms or slippage. Ask Phil Budwick (optioncoach) what he thinks of rolling ICs as he's co-author.
What about rolling out to a further term? Suppose the underlying is not showing any directional change, but get more volatile. My directional opinion is unchanged, but the wider moves are threatening my money management stop. It seems that a further month spread would get me a lower delta until things either calm down, or I exit for the same loss but after a more convincing underlying move. And rolling might even pay for its commissions. What am I missing?
