#TradeSchool I’m sitting on the short $SPX Dec 20th 2690/2665 put spread expiring today. Nice open followed by steep dive. Spread went from around 3.00 at open to over 9.00. That’s the peril you face sitting on ATM spreads expiring same day. So I was facing a loss, watching the charts. If it wasn’t for the TICKs, I probably would have exited at the lows. While the SPX consolidated flat-on-day, it looked like it wanted to break lower. But the TICKs, which I always have on my screens right next to SPX, showed a bottoming and then steady trend higher. So I felt comfortable waiting for the TICK trend to break before exiting, but it didn’t break and the SPX eventually lifted. Not sure how high we’ll get, but at least I didn’t panic exit at lows.
