What Is an Engulfing Scanner?
An engulfing scanner is an automated detector: it evaluates the last two closed candles on every pair, flags the bar that engulfs its predecessor, and labels the result a continuation or a reversal — so you assess context instead of hunting the pattern by hand.
The value is not the pattern itself — it is the filtering. Thousands of two-candle combinations technically qualify as engulfing across a 400-pair universe every hour. A graded engulfing scanner keeps only the ones that carry a real shift in delivery and discards the rest.
The Engulfing Candle in an ICT Frame
Retail teaching treats the engulfing candle as a standalone reversal signal: a big body that swallows the prior body. That definition is too loose. In an ICT / Smart Money Concepts frame, what matters is not the pattern’s shape but what it proves about order flow.
A candle that closes decisively through the prior candle’s range is a form of Displacement — a burst of one-sided delivery that leaves the prior balance behind.
When a green bar closes above where a red bar opened, or a bar’s close runs fully past the previous high, price has changed how it is being delivered. That is the same idea behind a Change in State of Delivery (CISD): the algorithm stops delivering in one direction and starts in the other.
So the useful question an engulfing scanner answers is not "was there an engulfing candle?" but "did this momentum candle continue the existing move, or flip it?" Those are two different trades, and lumping them together is why the naive pattern feels random.
This reframing also explains why body size alone is a weak filter. A wide-range bar in the middle of an established trend proves little; a decisive close through a level that just took liquidity proves a lot.
The engulf that matters is the one resolving a specific liquidity event — a swept low, a run on equal highs, a poke past a session extreme — because that is where delivery genuinely rotates. A scanner that grades the close against the prior range is, in effect, testing whether that rotation actually happened.
RUN vs REV: The Two Families a Super Engulfing Scanner Detects
LiquidityScan’s Super Engulfing (SE) engine splits every qualifying event into two families, each with a stronger "+" variant. This is the core of what a serious engulfing scanner detects.
RUN — continuation
A RUN is momentum in the direction the market is already moving. A bullish RUN needs both of the last two candles green, a new low taken beneath the prior candle, and a higher close. The market dipped to grab liquidity, then delivered up with force — a continuation, not a turn.
REV — reversal
A REV is the flip. A bullish REV needs a green candle immediately after a red one, closing back above the prior candle’s open. Sellers had control on the prior bar; this candle reclaims it. Bearish RUN and REV are exact mirrors of the above.
The "+" full-engulf filter
The "+" (plus) variant fires only when the candle’s close fully engulfs the previous candle’s high (for a bull) or low (for a bear) — a body close beyond the entire prior range, not just its body.
RUN+ and REV+ are the strongest reads because the close, not just an intrabar wick, ran past the extreme. That single filter separates a genuine displacement close from a candle that merely poked and faded.
A stock engulfing indicator paints an arrow on any bar whose body covers the prior body. It has no concept of direction context, no distinction between continuation and reversal, and no measure of how convincingly the close cleared the prior range. On a volatile 5-minute crypto chart it will fire dozens of times a session, most of them meaningless chop.
Grading fixes this by attaching meaning to each event. RUN tells you it is a continuation read; REV tells you it is a reversal read; the "+" tells you the close — the only price that cannot repaint — cleared the whole prior candle.
You are no longer staring at undifferentiated arrows; you are reading a classified event you can filter by.
| Aspect | Naive engulfing indicator | Graded engulfing scanner (SE) |
|---|---|---|
| What it flags | Any body-over-body engulf | Classified event: RUN / RUN+ / REV / REV+ |
| Direction context | None — same arrow for continuation and reversal | RUN = continuation, REV = reversal, explicitly labeled |
| Strength filter | None | "+" fires only when the close fully engulfs the prior high/low |
| Repaint | Often intrabar / repaints | Closed-candle only; does not repaint |
| Trade geometry | None | Entry + SL + TP1/TP2/TP3 at fixed R-multiples |
| Coverage | One chart at a time | All pairs, 5m–1w, scanned each cycle |
The Entry, Stop, and TP1/TP2/TP3 Ladder
Super Engulfing is the only base scanner in the platform that ships a full trade skeleton: an entry, a stop-loss, and a three-step take-profit ladder at 1:1.5, 1:2, and 1:3 risk-reward, with the stop moved to breakeven after TP1 is tagged and a candle-count expiry budget so a stale setup is retired rather than left open.
Read this carefully, because it is the single most misunderstood part of any engulfing scanner. Those targets are geometric — they are drawn purely from the risk distance between entry and stop, multiplied out. TP1 is simply 1.5 times the risk; TP3 is 3 times it.
They are not predictions, not probabilities, and not a claim about how often price reaches them. The ladder gives you a consistent, mechanical framework to manage a trade; it does not tell you the trade will win.
What the ladder buys you is discipline. Every SE event carries the same structure, so your management is identical every time: risk one unit, bank partials at fixed multiples, protect capital at breakeven, and let the expiry budget close dead setups. The judgment — whether to take the setup at all — stays with you.
The breakeven-after-TP1 rule and the candle-count expiry are the quiet, important parts. Moving the stop to breakeven once TP1 prints converts a live trade into a free-roll: worst case is now scratch, not a full loss.
The expiry budget solves the opposite failure — a setup that neither wins nor loses but drifts sideways, tying up attention and risk. Retiring it on a candle count keeps the book clean and forces the next decision, rather than letting a stale engulf linger as a false open position.
Sub-Hour Coverage and Why No-Repaint Matters
SE runs on 4h, 1d, and 1w hourly timeframes plus 15m and 5m sub-hour timeframes, so both swing and intraday traders get coverage. The intraday windows are where an automated engulfing scanner earns its keep — no human can watch 5-minute closes across hundreds of pairs.
Every read is taken on confirmed, closed candles only; the live forming bar is always dropped. This matters more than it sounds. An indicator that evaluates the in-progress candle can show a beautiful engulf that evaporates before the bar closes — it repaints, and your backtest lies to you.
Because SE grades only after the candle seals, a RUN+ you see now is the same RUN+ in the history a week later. The signal is stable, which is the whole point of trusting an alert you did not personally watch form.
No-repaint discipline also protects the trade geometry. If the entry candle could shift, so could the stop and every target derived from it — your risk unit would be a moving number.
Sealing the candle first fixes the entry and stop, which fixes the whole R-multiple ladder, so the plan you see at detection is the plan you manage. On the sub-hour timeframes, where bars close every five minutes, that stability is the difference between a usable alert and a mirage.
The Workflow: From a Graded SE to a Managed Trade
Automated detection is step one, not the whole job. The honest workflow looks like this:
- The scanner surfaces a graded SE with its entry, stop, and R-multiple levels already drawn.
- You check higher-timeframe context. Is a bullish REV on 15m happening in a discount relative to the daily dealing range, into an unmitigated Order Block or below a swept Draw on Liquidity? Or is it fighting a clean daily downtrend?
- You execute and manage using the ladder — partials at TP1/TP2/TP3, stop to breakeven after TP1, and let the expiry budget close it if it stalls.
A worked example
Say BTCUSDT on the 15m has run down all morning and taps a session low, sweeping sell-side liquidity at 61,200. The next 15m candle closes green at 61,540, back above the prior red candle’s open at 61,480, and its close clears the prior candle’s high of 61,510. That is a bullish REV+ — reversal family, full-engulf variant.
The scanner sets entry near 61,540, stop below the swept low around 61,120, and projects TP1 at roughly 62,170 (1:1.5), TP2 near 62,380 (1:2), TP3 near 62,800 (1:3).
Before you act, you confirm the swept low sits at a daily discount and lines up with a prior Fair Value Gap (FVG) below — context that supports a reversal.
You take it, bank a third at TP1, slide the stop to breakeven, and let the rest run. If price never reaches TP1 and the candle budget expires, the setup closes and you move on. The geometry did its job whether or not this particular trade paid.
Honest Limits of an Engulfing Scanner
An engulfing scanner is a detector and a framework, not an oracle. Three limits are worth stating plainly.
First, the RR ladder is geometry, not a win rate — the platform does not compute or publish accuracy, and the 1:1.5/1:2/1:3 levels say nothing about how often price gets there.
Second, context is your job: SE finds the momentum candle, but whether it fires into HTF alignment or against it determines the quality, and the scanner does not grade that for you.
Third, no pattern is regime-proof; the same RUN read behaves differently in a trend versus a chop, which is exactly why you verify on your own data before leaning on any variant.
Used this way — as an automated first pass that hands you graded, non-repainting engulfing events to judge — the engulfing scanner turns hours of chart-hunting into minutes of decision-making.
Frequently Asked Questions
What is the difference between a RUN and a REV engulfing signal?
RUN is a continuation read — momentum extending the current direction after taking a nearby high or low. REV is a reversal read — a candle that reclaims the prior candle’s open in the opposite direction. Same engulfing mechanic, opposite intent, which is why a scanner that does not separate them feels random.
Does the engulfing scanner tell me the trade will be profitable?
No. It detects the pattern and draws a geometric entry, stop, and TP1/TP2/TP3 ladder at fixed risk multiples. Those targets are math, not forecasts — the platform publishes no win rate and makes no outcome guarantee. You still judge context and manage risk yourself.
Why does closed-candle detection matter for engulfing patterns?
Because an engulf that looks perfect mid-candle can vanish before the bar closes. Evaluating only confirmed, closed candles means the signal does not repaint: the RUN+ you see now is identical in next week’s history, so alerts you did not watch form are still trustworthy.
What timeframes does the Super Engulfing scanner cover?
It runs on 4h, 1d, and 1w for swing reads plus 15m and 5m for intraday. The sub-hour windows are where automation matters most, since no trader can manually watch 5-minute closes across hundreds of pairs at once.
