Criminy, Jim, it didn't take me 43 years to be wrong thousands of times!
The market is simply gunning for your signal this time. A cancelled day of trading. Signal in expiry week. Today marginally down on the Dow but up on the OEX (which one is your signal pegged to? OEX, I guess, based on your comment). Meaning if we're down tomorrow, was the signal hitting on the proper day... or does that mean we go up Friday? Too much for this Freepish brain.
I guess you signal could be pushed a day late, too, giving us til Monday to hit 557 OEX? That way we can chop around in expiry week and not let anyone make money.
Glad to be watching quietly...
