Phil, if you are trying to offset your IC when a big move happens wouldn't it be easier to buy an ATM straddle for every 3-4 spreads u sold instead of unwinding the spread itself. Cheaper commish and less vig.
In addition, much easier to take off hedge when things settle down?

Phil,
Many here are end-of-day traders. I do look at one-minute realtime charts using the TOS platform but it's not "second nature". You mentioned you have quite some experience with this (TICK is one thing you looked at).
Can you offer some low-hanging-fruit guidelines for assessing SPX intraday?
Quote from GATrader:
Your are correct . I mispoke. What I meant was since you are worried about protecting the sold vertical, it might be simpler to buy 1 single call or put to protect the bad side. Cottle calls it a slingshot, some call it pregnant fly. So if u were in trouble on the put side you'd buy an ATM put for every 3-4 spread u sold. It then wouldturn out to be a pregnant fly on the downside. So if you are worried about the 1185/1180 put spread in Emini since you sold 20 of them, you'd buy 5 1190's ,Your pnl profile would be like a pregnant fly. Simple as that.
You might even make more than just capping your losses.

Had an order in for a 10 spx 1240/1255 spread at .35 credit.
The b/a hit .30/.60 and I could not get a fill - talk about the mm's being greedy! Oh well, there's always tomorrow.

You must have been fighting me to get that filled. I had the exact same order, but here's the strange part.
I had the order in for a $0.35 credit for well over an hour. The SPX was up about 3 to 3.5. I then changed it to $0.30 and got filled in 2 minutes. SPX was still up between 3 to 3.5. I didn't really look carefully at the fill until I put it in my log. I realized I actually got filled at $0.35??!
Looking at the OX trade screen, it clearly shows that my original $0.35 order was cancelled and the fill at $0.35 was for the order placed for a $0.30 credit.
I am glad, but I'd prefer consistency because I know that I lose a lot more than I win on getting good fills.

Followup to my post below.
A couple of days ago I closed out the 1285 short leg on my Oct SPX 1285/1300 bear call spread. I was able to buy that leg back for $0.05. After the fill I placed a GTC order to sell the 1300 leg for $0.05, hoping to get lucky. Got it filled today. So I was able to close out the entire bear call for only the low OX commission. That allowed me to place the spread posted below and I got a better than expected fill.
Maybe some MM feels guilty about all the money they took from me in July.![]()
