Gap-and-Go vs Gap-and-Crap — Decision Tree
Posted: Sat Sep 05, 2026 10:46 am
Gaps are not setups. Gaps are **conditions**.
Took me longer than it should have to internalize that. Gap-up used to mean "I have to be involved." Usually meant I had to be involved on the wrong side of the spread.
### Quick tree (what I run through)
### "Go" tells (none sufficient alone)
Premarket higher lows into the bell. Spot bids defending a level on L2 (with salt). Index not dying under the name. Spread still tradeable. That's the boring list. Boring is good.
### "Crap" tells
Vertical PM spike, no consolidation, chat euphoria. Offering rumor mid-spike. Wide spread that only "looks tight" on a 5-min chart. You needed the gap to "make back yesterday" — that last one is personal. I've been that guy.
### Personal rule
If I can't state the **invalidation** in one sentence before entry, it's gap-and-crap for me — even if it runs without me. Missing a runner beats inventing a plan mid-fill.
How do you define invalidation on a gap-and-go before you click?
Fade gaps at all, or is that a hard skip in your book?
What PM volume behavior is your strongest "go" tell?
Anyone have a gap rule that saved them this week — specifics welcome?

### Quick tree (what I run through)
Code: Select all
Gap up + rising PM volume + clean catalyst
→ candidate for continuation IF open holds PM support / OR break
Gap up + fading PM volume + recycled headline
→ fade candidate only if YOUR fade playbook exists (else skip)
Gap down + panic headline + climactic volume
→ not an automatic long; wait for reclaim structure
Gap into earnings print
→ binary: size down or flat
