Order Block Filled or Just Tapped? The 5 Checks Before You Enter

An order block filled or tapped looks identical for the first candle. Price comes back to the zone, touches it, and one of two things is about to happen: the participant who built the position defends it and price leaves — the block is respected, and the entry works — or the touch was just liquidity being collected on the way through, and the block fails. Traders who enter on the touch are guessing. Traders who wait for one of the five checks below are deciding.

This is the check-list we use on NQ, in the order we run it. It works on any timeframe; the examples are the 1-hour and 15-minute because that is where most evaluation entries happen.

Order block filled or tapped: what “filled” actually means

An order block is the last opposing candle before a displacement — the last down-candle before the strong up-move that broke structure, or the last up-candle before the drop. It marks where a large position was built (the same footprint volume-profile traders call a high-volume node — see CME’s market-profile primer). "Filled" (some say mitigated) means price has returned to that zone and the orders resting there have been consumed. The question that matters for you is not whether the block was touched. It is whether it was respected — did price react at it — or broken — did price close through it.

A tap is a touch with no reaction yet. A fill with respect is a touch followed by rejection. A fill with a break is the block failing. The five checks tell those three apart — this is how to know if an order block is filled, mitigated, or simply tapped and about to fail.

Check 1: the wick test

Watch where the candle that entered the block closes. A wick into the zone with a body that closes back outside it is the block being respected: sellers pushed in, buyers absorbed it, and the candle's body records who won. A body that closes inside the block is undecided. A body that closes through the far side of the block is a break.

On the 15-minute, give the first touch one candle. On the 1-hour, one candle. Do not judge on the wick while the candle is still open; a 15-minute candle that looks like a rejection at minute six is frequently a close-through at minute fifteen. The close is the vote.

Check 2: the 50% line

Draw a line through the midpoint of the order block candle (open-to-close body, or the full candle if the wicks are small). Strong blocks are respected in their upper half in a bullish case — price dips into the zone, reacts before or at the 50% line, and leaves. A block that gets pushed through its midpoint has lost most of its defenders; if price then closes below the low of the block, it is done.

This is the single most useful refinement to plain order-block trading: it turns a zone into a scale. Reaction above 50% = strong. Reaction at 50% = acceptable. Reaction below 50% = weak, size down or skip. Close through the low = failed.

Check 3: displacement and the fair value gap

A block that is being respected does not just stop price; it produces a move — a displacement candle, larger than the recent ones, that breaks the short-term high (in a bullish case) and usually leaves a fair value gap behind it. That candle is the proof that a real participant acted at the level.

No displacement, no confirmation. Price can sit on a block for six candles and drift; that is not respect, it is indecision, and it usually ends with the block breaking. If you entered on the touch, the absence of displacement is your early warning. If you waited, it is the reason you are still flat.

Check 4: lower-timeframe change of character

Drop one or two timeframes. If your block is on the 1-hour, look at the 5-minute. Coming into the block, the 5-minute is making lower highs and lower lows — that is the pullback. A respected block flips that: the 5-minute prints a higher low inside the zone and then takes out the last lower high. That break of the small-timeframe structure is the change of character, and it is the earliest objective entry signal you get.

It also gives you the stop: below the higher low that formed inside the block. Tight, defined, and tied to the thing you are actually betting on.

Check 5: the order block retest holds

After the displacement, price often comes back to the block's edge or to the gap the displacement left. If that retest holds — a wick into it and a close back away — the block has now been respected twice, and the trade has its lowest-risk entry. If the retest fails and price closes back inside the block, the first displacement was a fake-out and the block is likely to break on the next visit.

Many traders skip this check because the first displacement already ran and they feel late. The retest is not late. It is where the second entry lives, and it is where the first entry gets its confirmation.

Time and volume as tie-breakers

Two blocks can pass the same checks and behave differently, and the difference is usually when. A 1-hour block tested at the 10:00 am ET candle close, with the New York session behind it, carries far more weight than the same block tested at 3:00 am on Asia volume. Volume on the touch tells the same story: a spike at the zone followed by quiet is stops firing and nothing else; a spike followed by rising volume on the displacement candle is participation. When the checks are split, let time and volume decide, and skip anything that fails both.

Doing all five on one screenshot

Here is a real sequence, NQ, 1-hour bullish order block at 20,100–20,130 (the last down-candle before Tuesday's push to 20,260).

1. Wednesday 9:00 am ET: price pulls back into the block. The 9:00 candle wicks to 20,108 and closes at 20,124 — above the 50% line at 20,115. Checks 1 and 2 pass.
2. 9:45: the 15-minute prints a 40-point candle up through 20,150, leaving a gap between 20,132 and 20,141. Check 3 passes.
3. On the 5-minute, the higher low at 20,112 was followed by a break of the 9:30 lower high. Check 4 passed at 9:40, which is where the first entry was, stop at 20,105.
4. 10:20: price retests the gap at 20,138, wicks to 20,135, closes at 20,149. Check 5 passes; second entry, same stop.
5. Tie-breakers: the 10:00 4-hour close was above the block, and volume on the 9:45 candle was the session's highest. Nothing to argue with.

Target was the overnight high at 20,190; it printed at 11:05. Had the 9:00 candle closed at 20,109 instead — below the 50% line — the read would have been "weak block, wait for the retest or skip," and the trade would have been half size or none.

What to do with a block that fails

A broken order block is not a loss of information; it is new information. The zone that was demand is now a place where trapped buyers will sell into any bounce — the same flip that makes broken support into resistance. Mark it as a supply zone, wait for price to return to it from below, and run the same five checks in reverse. Half the good short entries on NQ come from a bullish block that failed an hour earlier.

Let the chart answer the checks

MyTradingBuddy runs this read on the chart you have open in TradingView: it marks the blocks that broke structure, shows where the current candle sits relative to the zone and its midpoint, flags displacement and the gap, and names the level that would say the block failed. You still make the call. It just makes sure the five checks are in front of you before you do. Three-day trial for $14.07: try it on your own order block.
