Add another unit 1121.75. Yep, although it is somewhat inaccurate to add overnight since NFV can move too, negating the edge you think you have. But it is worth a shot, and even if it is off, the odds of being off by more than a couple of is very small.
Adding in the overnight session turns out to have been slightly innacurate, not because it was terribly off (it was off by about 2) but because the market continued higher after the open giving us a three handle difference better entry. Sometimes art, sometimes science...
So did it happen? The Sept position was 4 ctrs short average app. at 1105.5, so the new Dec should be 4 ctrs from 1100.5 or so... (It is kind of easier to follow if you post the average.)
It doesn't matter. You are focusing on the wrong thing. Some people use longer dated options and some people use SPY. It is irrelevant. If you prefer, add a handle to the cost column per four contracts for rolling.
It sure does when your trading vehicle expires and you still want to be in the position. Also if you keep adding (which is still a possibility) it will confuse readers which contract you are refering to. So just for the record, short 4 Dec ctrs from 1100.5 and this position started on 9/2...
Using any particular instrument will confuse a little bit if that is not the instrument you are trading. We should just use SPX as our entry and assume SPY as the trading vehicle in the real world, regardless of what I use. The difference between them are negligible. Imo Rolling contracts is more confusing to keep straight. In fact we have to do nothing at this point. We could pretend our entries are in SPX (SPY), since there is nearly no difference between the Sep futs contract and SPX at this point.
And the bacon strips I'm sportin are skyrocketing in thickness. 50 handles of short edge and we be a hurtin!
