What does it mean when the Alligator is sleeping?

That the three lines are entwined and flat — the fast, medium and slow averages all agree, which happens when price has no direction. Bill Williams' framing is that this is the market's normal state and that trend rules should simply not fire in it. Expressing 'entwined' precisely enough for an EA is the hard part, which is why a measured filter such as ADX is often used as a stand-in.

Why is the Alligator built on median price?

Because Bill Williams designed it to track the midpoint of the bar rather than its settlement, which makes the lines slightly steadier on instruments with long wicks. iAlligator takes a full ENUM_APPLIED_PRICE argument, so Close and the rest are available — Median is simply the conventional default in MT5.

Do the forward shifts matter for an EA?

Yes. Each line is displaced forward by its own amount inside the indicator, so buffer values do not line up with the current bar the way a plain moving average does. Comparing price directly to a shifted line compares two different points in time. Read the buffer at the offset that corresponds to the bar you mean.

Alligator or moving averages — is there a difference?

Structurally the Alligator is three smoothed averages, so yes, it is a moving-average system. What it adds is the specific configuration — median price, SMMA, and three different forward shifts — plus a framing that treats the entwined state as an instruction to stand aside rather than a state to trade through.

Can I build an Alligator EA without coding?

Yes for crossovers and price-versus-line rules. The Alligator Cross template wires lips and teeth into a Cross node with all periods, shifts, method and applied price as EA inputs. Detecting the fanned-out or entwined state is the exception — that is a three-way ordering test the node palette does not express.

How should I validate settings before going live?

Backtest on quality tick data first, then run the EA on a demo account before risking money. When optimising, hold back data the search never saw and prefer settings that stay profitable across periods over the single in-sample peak — chasing that peak is overfitting the noise. No default or preset here is a performance promise; every value is a starting point to re-validate on your own pair and broker.

Alligator

The Alligator is three smoothed moving averages of median price, each shifted forward by a different amount, drawn as a jaw, teeth and lips. Its whole purpose is to make the difference between a trending market and a sleeping one visible at a glance.

Periods: 13 / 8 / 5
Shifts: 8 / 5 / 3
Method: Smoothed (SMMA)

What the Alligator tells you

Three averages of different speeds, each pushed forward by a different amount, spend most of their time tangled together. That tangle is the point: Bill Williams' framing is that the market sleeps most of the time, and the only tradeable state is when the three lines separate and fan out in order.

Lines entwined: the market is sleeping — stand aside
Lines fanned out in order: a trend is running
Lips crossing back through teeth: the move is losing its grip

1 Smooth median price over 13, 8 and 5 bars
2 Shift each result forward by 8, 5 and 3
3 Read whether the three lines are apart or entwined

Tampilkan rumus & detail perhitungan

The Alligator is three smoothed moving averages of median price, each displaced forward by a different number of bars:

Jaw (buffer 0) — a 13-period smoothed moving average of median price, (High + Low) / 2, shifted 8 bars forward.
Teeth (buffer 1) — an 8-period smoothed average of the same series, shifted 5 bars forward.
Lips (buffer 2) — a 5-period smoothed average, shifted 3 bars forward.

The smoothed moving average (SMMA) is the slowest of MT5’s four methods — each new bar nudges a running value rather than dropping an old one out of a window — which is what keeps the three lines calm enough to entwine convincingly during a range. The staggered forward shifts are what turn three ordinary averages into a fan: without them the lines would simply track each other with different lags, and the visual distinction between sleeping and awake would be much weaker.

In MQL5 the call is iAlligator(symbol, period, jaw_period, jaw_shift, teeth_period, teeth_shift, lips_period, lips_shift, ma_method, applied_price) and it returns a handle to three buffers. Both ma_method and applied_price are real arguments; the SMMA-on-median configuration is the conventional default, not a fixed property. Bill Williams introduced the Alligator in the 1990s alongside Fractals and the Awesome Oscillator.

Di Builder

The Builder's Alligator node exposes the three period/shift pairs, the averaging method and applied price, and passes them to iAlligator. It defaults to PRICE_MEDIAN and MODE_SMMA, which is Bill Williams' original configuration.

Catatan implementasi

iAlligator publishes all three lines from one handle, so a crossover rule is two Alligator nodes reading different buffers of the same indicator.
The forward shifts are applied inside the indicator, so buffer values already sit ahead of the current bar — a comparison against price needs the same care as Ichimoku's cloud.
'The lines are fanned out in order' is a three-way ordering test across all buffers; the node palette has no ordering node for the Alligator, so that state needs custom MQL5 or a proxy such as ADX.

Gabungkan Alligator dengan indikator lain

Satu indikator jarang berdiri sendiri. Kombinasi ini menutupi titik buta Alligator.

Alligator + Awesome Oscillator

Lips crosses teeth
AO crosses zero
Buy

Mengapa: Pair Bill Williams' regime tool with his momentum tool, so a fan that is opening is confirmed by momentum crossing zero
Kondisi terbaik: Trend start

No single-flow template pairs the Alligator with the Awesome Oscillator. Start from Alligator Cross and add an AO node with a Constant zero into a Cross node.

Buka Builder →

Alligator + ADX

ADX > 25
Lips crosses teeth
Buy

Mengapa: Replace the visual 'is it sleeping' judgement with a measured trend-strength threshold, which an EA can evaluate without ambiguity
Kondisi terbaik: Trending

No single-flow template pairs the Alligator with ADX. Start from Alligator Cross and add an ADX node with a Compare at 25 into an And gate.

Buka Builder →

Alligator + Fractals

Lines fanned up
Price breaks the last fractal high
Buy

Mengapa: Use the fan for direction and the last swing level for the trigger, which is closer to how Bill Williams intended the tools to be used together
Kondisi terbaik: Breakout

No single-flow template pairs the Alligator with Fractals. Start from Alligator Cross and add Fractals nodes with a Price node into a Cross.

Buka Builder →

Alligator + Gator Oscillator

Both Gator halves growing
Lips above Jaw
Buy

Mengapa: The same three averages read as distances instead of curves. Judging by eye whether the lines are converging is the hard part of using the Alligator, and the Gator turns it into two numbers that either grew or did not — so the fan supplies direction and the histograms supply the phase. Not an independent confirmation: every Gator value is computed from these three lines
Kondisi terbaik: Trending

Parameter

Nilai awal untuk divalidasi pada pasangan dan timeframe Anda sendiri — bukan pengaturan yang dijamin.

Parameter	Default	Rentang uji yang disarankan	Fungsinya
Jaw period / shift	13 / 8	8–21 / 5–13	The slowest line and its forward displacement. Widening it makes the fan slower to open and slower to close.
Teeth period / shift	8 / 5	5–13 / 3–8	The middle line. Most crossover rules use this as one side of the comparison.
Lips period / shift	5 / 3	3–8 / 2–5	The fastest line. Shortening it produces more crossovers, most of them inside the tangle.
Applied price	Median	Median / Close / Open / High / Low / Typical / Weighted	Price series the three averages run on. Median — (high + low) / 2 — is Bill Williams' original choice and MT5's convention here, not Close.

Preset awal

Classic 13 / 8 / 5 Bill Williams' original

Faster 8 / 5 / 3 Opens sooner, more false starts

Slower 21 / 13 / 8 Swing-level regime only

Contoh pasar

Di mana Alligator bekerja, di mana ia gagal, dan bagaimana filter mengubah hasilnya.

Berhasil

The fan opens

After a flat stretch the three lines separate in period order and price runs — the awakening the indicator is built to make visible.

Gagal

Crossover inside the tangle

Lips and teeth cross back and forth while all three lines sit on top of each other. Each cross is a trade in a market the indicator itself is calling asleep.

Difilter

Regime filter suppresses the noise

Add a trend-strength condition and the entwined-period crossovers are all skipped, leaving the ones where the fan is genuinely opening.
