Who said I'm exposing myself to evernight SPX Risk? I said I'm daytrading SPX. The whole Point of this Thread is to find a cheap way of eliminating Vega.
Interesting. The chart of the VIX for Thurs shows a 2 point rise which I assume was around the time that the announcement came out. Without knowing the details of your trade, I assume you had a wide iron condor, and this little jump - which is a pretty normal variation of the VIX in a day - caused a temp jump in your short strikes, and triggered your stops. And if the credit received for each leg of the IC was a low number like say 2 or 3, then all it takes is a little widening of the spread and the stops get hit. Not sure what type of vega hedging can help with a 2 point rise in the VIX like this. Buying a VIX call, even a weekly one, won't work as that will not move enough for a small rise in the VIX like this. In Mar and Apr, I traded a lot of SPX fly's and IC's so I'm genuinely curious about your situation.
Your initial post is a little confusing.I get that you are trading IF/IC.Im assuming you are holding them..You say you are hedging the Vega risk with VIX calls and sell before the bell.Im assuming you mean your VIX hedge. So you are day trading VIX(not holding overnight),and exposing yourself to overnight risk?? Now it appears you are day trading SPX?? Im assuming as a delta hedge,which makes sense?? But not carrying the SPX overnight?? If you blow out of your hedge,do you flatten Deltas?? I think you are over complicating these type of trades and missing the forest thru the trees.. If vol blows up( intraday) and I have done a good job managing my delta /gamma,Im putting more on... If you are that concerned with Vega,roll your longs out..
