Most traders see a gap and panic or chase.

Elite traders see a gap and read it like a map.

Here's everything about gaps the market doesn't teach you 🧵👇

2/
A gap = price jumped from yesterday's close to today's open.

No trades in between.

That empty space on your chart?
The market screaming:
"Everything changed overnight."

3/
Gaps aren't born at 9:30 AM.

They're built between 4 PM and 9:29 AM.

Earnings. FDA. Upgrades. Geopolitical shock.
While you slept, institutions were repricing.

By the time the bell rings , the gap is already decided.

4/
Two stages most traders completely ignore:

After-hours: First knee-jerk reaction. Thin liquidity. Retail + algos. Usually an overreaction.

Pre-market: Institutions arrive. Price gets refined. Spreads tighten.

The 9:29 AM price always tells more truth than the 4:15 AM spike.

Watch both. Trust the latter.

5/
Pre-market volume is your cheat code.

Big gap + LOW pre-market volume = weak, likely to fill
Big gap + HIGH pre-market volume = strong, likely to continue

One number changes your entire bias before the open.

6/
There are 4 types of gaps.

Trade them all the same way and you'll lose money on all 4.

Here's how to tell them apart 👇

7/
Common gap
→ Inside a range. No real catalyst.
→ Fills fast. Low edge.
→ Fade it or skip it entirely.

Breakaway gap
→ Explodes OUT of a base or consolidation.
→ New trend starting. High volume confirms.
→ Respect it. Don't fade it. Go with it.

8/
Runaway/Continuation gap
→ Mid-trend. Trend is accelerating.
→ Often marks the MIDPOINT of the entire move.
→ Trail stops to the gap. Add on pullbacks that hold it.

Exhaustion gap
→ Late in a mature trend. Climax energy.
→ Last gasp before reversal.
→ Watch for no follow-through. Then fade it hard.

9/
How do you tell exhaustion from continuation?

One word: context.

Early in trend + high volume = continuation
Already run far + crowded + no follow-through = exhaustion

Same gap. Completely opposite trades.
Context is everything.

10/
Every gap has 3 levels you must mark BEFORE the open:

📍 Prior close: bottom of gap up / top of gap down
📍 Gap open : top of gap up / bottom of gap down
📍 Gap midpoint : the magnet in between

These aren't just lines.
They're where the battles happen all day.

11/
Gaps are the most powerful support and resistance on your chart.

Here's why:

Price SKIPPED that zone entirely.
No one traded there.

Trapped longs. Unfilled institutional orders. Emotional anchors.

Every time price revisits that zone — reactions are sharp, fast, and violent.

That's not magic. That's market microstructure.

12/
Gap UP rules:

→ Bottom of gap = SUPPORT
→ Holds above it = bull trend intact ✅
→ Closes back INTO the gap = danger ⚠️
→ Full fill to prior close = structure broken 🔴

Gap DOWN rules:

→ Top of gap = RESISTANCE
→ Rejects from upper edge = shorts reload ✅
→ Closes back ABOVE the gap = squeeze incoming ⚠️
→ Full fill = bears lost control 🔴

Mark these levels. React to price at them. Simple.

13/
Gap fill = price trades all the way back to the prior close.

Stats you need burned into your brain:

  • Common gaps fill ~90% of the time
  • Exhaustion gaps fill ~85%
  • Continuation gaps fill ~75%
  • Breakaway gaps fill ~65%
  • Low volume gap = higher fill probability.
    High volume gap = lower fill probability.

    Volume is everything.

    14/
    Gap DOWN that stays open for days/weeks:

    → Market accepted the repricing lower.
    → That upper gap edge = hard resistance.
    → Don't buy aggressively into it.

    But when it finally fills after weeks?
    The move is VIOLENT.
    Shorts panic. Mean reversion buyers pile in.
    Most profitable fills come from the longest-open gaps.

    15/
    Gap UP that stays open for days/weeks:

    → Demand accepted the higher price. Fully.
    → As long as price holds above it = trend intact.
    → That gap zone = your trailing stop reference.

    First close BACK INTO the gap after weeks?
    That's not a dip.
    That's a warning.

    16/
    Gap and GO vs Gap and FADE:

    GO: Breakaway + high volume + sector aligned + index strong
    FADE: Common + low volume + weak context + index against it

    You don't guess which one.
    You read the pre-market tape and let context tell you.

    Bias is built before the bell. Not after.

    17/
    Pre-market checklist. Run this every single morning:

    ✅ What caused the gap? (catalyst quality)
    ✅ AH spike vs PM close — did price fade back? (overreaction?)
    ✅ Pre-market volume — high or low?
    ✅ Gap type — breakaway, runaway, or exhaustion?
    ✅ Sector + index aligned or fighting it?
    ✅ All 3 gap levels marked on chart?

    No checklist = no edge = gambling.

    18/
    Island Reversal — the rarest gap pattern:

    Price gaps up → consolidates → gaps DOWN in the opposite direction.

    The consolidation is left "stranded" like an island.

    Translation: Trapped buyers. Air pocket below. Violent reversal incoming.

    When you see one — respect it immediately.

    19/
    The edge isn't in trading every gap.

    The best gap traders skip 80% of them on purpose.

    They wait for:
    → Right gap type
    → Right volume
    → Right catalyst
    → Right context

    Fewer setups. Cleaner execution. Bigger R multiples.

    20/
    Final truth about gaps:

    Every gap is just one question:

    "Does the market accept this new price — or reject it?"

    Your job isn't to predict the answer.

    Your job is to wait for the market to show you.

    Then act with size and conviction.
