Quote from JohnGreen:
Spindr0 makes an excellent point about the adjustments. With an IC, you almost never make an adjustment that doesn't involve taking a profit on one side or the other, which is unlike many other positions which simply worsen with market movements against you. With the IC, it can't worsen on both sides at once.
This is now the situation that Mark is referring to--it's not so much about predicting the market, but rather keeping the risk in check and avoiding catastrophic losses. As an experienced IC trader, I heartily endorse that point of view as well.
The IC is not the "holy grail". You can and will have occasional losses. It's how much you can control and minimize those losses and maximize your good months that determines whether or not you are making an excellent return or losing your shirt.
Many of us also use some other techniques to keep the gamma/ delta situation nicely in check and preserve our credits within the overall context of the IC structure. I also recommend a trip through the elite trader archives for the "SPX Credit Trader" thread started by optioncoach who is still lurking about. It is long and involved, but contains much valuable insight into the inner workings of the thought processes of several veteran traders who used IC's as well as double diagonals and various credit spreads as their primary trading tools.
Thanks John. I have read through many threads on ET and some of the articles people have attached, including examples of IC adjustment trades. One of the articles I read had someone roll down the whole position but in so doing sold more total contracts of the further OTM options, which didn't sit well with me because it seemed like they're adding much more risk to the initial trade. I think this was also the case with the SPX credit Trader thread, but I can't remember.
I'm a directional trader and have a pretty good track record (I'm living off my trading), but boy, it would surely be nice to be able to make consistent profit trading a neutral strategy like IC! The adjustment technique seems to be critical for success, and seeing and hearing many who fail using that strategy makes me wonder what it takes to be successful in it.
