What do step and maximum actually change?

They control the acceleration factor, which is the fraction of the distance between the stop and the trend's extreme that the stop closes each bar. Step is how much that fraction grows on every new extreme; maximum is its ceiling. A larger step tightens the stop sooner and produces more flips; a larger maximum lets a long trend eventually be stopped out on a small pullback. Neither is a lookback period, and neither makes the indicator 'see' more history.

Why does SAR whipsaw so badly?

Because it has no concept of a market without a trend. SAR is always on one side of price or the other, so in a range it simply alternates, and in the classic stop-and-reverse form every alternation is a full position reversal. The indicator is not malfunctioning — it is answering the question it was built for, which assumes a trend exists. Deciding whether one exists is a job for something else, which is why the Builder template gates it behind ADX.

Are the dots support and resistance levels?

No. A SAR dot is a stop level derived from the trend's own extreme and an acceleration factor — it has nothing to do with where buyers or sellers previously transacted. It can coincide with a structural level, but treating it as one leads to placing entries at dots, which is the opposite of what the value means.

Can SAR be used as a trailing stop in an EA?

Yes, and that is its original purpose. The Builder's trailing-stop node has a Parabolic SAR mode that moves the stop to the current dot each bar, with its own step and maximum exposed as EA inputs. The SAR Flip + ADX template uses exactly that for the exit, so the indicator manages the trade after entry instead of a fixed pip distance doing it.

Can I build a Parabolic SAR EA without coding?

Yes for the flip and for the trailing stop. The SAR Flip + ADX template wires a SAR node against the Bid price with Cross nodes, gates both directions on ADX above 25, and trails the stop with a second SAR — step, maximum and the ADX period are all EA inputs. Counting flips or measuring dot spacing over several bars is the exception and needs custom MQL5.

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. Be especially careful optimising step and maximum: because they change trade count as well as trade quality, a setting can look better purely by trading less on one window. Hold back data the search never saw and prefer settings that stay profitable across periods over the single in-sample peak. No default or preset here is a performance promise.

Parabolic SAR for MT5 traders

What Parabolic SAR tells you

SAR answers one question per bar: where would the stop have to sit for this trend to still be intact? It places that level on the far side of price and drags it closer every bar, faster each time the trend makes a new extreme. When price finally reaches the level, the indicator declares the trend over and puts the dot on the other side.

Dots below price: the current trend reading is up
Dots above price: it is down
SAR is always on one side or the other — it never reports 'no trend'

1 Track the extreme reached in the current trend
2 Pull the stop toward it, accelerating each new extreme
3 Flip sides the moment price touches the stop

Tampilkan rumus & detail perhitungan

Parabolic SAR is a stop level that walks toward price, and it is defined recursively rather than as an average:

Fix the direction of the current trend and the extreme point (EP) reached so far — the highest high in an uptrend, the lowest low in a downtrend. Set the acceleration factor (AF) to the step, 0.02 by default.
Move the stop a fraction of the way to that extreme: SAR = SARprev + AF × (EP − SARprev).
Every time the trend posts a new extreme, raise AF by one step, up to the maximum (0.2 by default). The stop therefore closes in faster the longer the trend runs.
Clamp the result so the stop can never sit inside the previous two bars’ range — without this, a wide bar could place the stop where it would be triggered immediately.
If price reaches the stop, flip: the trend direction reverses, the new SAR becomes the old EP, the EP resets to the current bar’s extreme, and AF resets to the step.

The consequence of step 3 is the whole character of the indicator. Early in a move the dots trail loosely; by the time the trend has posted many new extremes they are tight against price, so the same setting that gives a young trend room will exit a mature one on a shallow pullback. That is deliberate — Wilder’s point was that a trend that has already run deserves less rope.

In MQL5 the call is iSAR(symbol, period, step, maximum) and it returns a handle to one buffer. There is no applied-price argument, because the calculation reads highs and lows directly, and there is no period argument at all — step and maximum are rates of acceleration, not lookback windows. That makes SAR one of the few MT5 indicators where “what period should I use?” has no answer, and where tuning changes how quickly the tool gives up on a trade rather than how much history it considers.

Buffer

Indeks	Buffer	Digambar di MT5 sebagai	Isinya
0	MAIN_LINE	Dots	The stop level for the current bar, plotted on the price scale. MT5 draws it as one dot per bar and never joins them, because the series jumps sides on a flip — there is no continuous line to draw.

Catatan platform

Fungsi MQL5

iSAR

Applied price

Indikator ini tidak menerima argumen applied price.

Di Builder

iSAR takes only a symbol, a timeframe, a step and a maximum. There is no ENUM_APPLIED_PRICE argument, because the calculation reads the bar's high and low directly rather than a single chosen price series. The Builder's SAR node therefore exposes step, maximum, shift and timeframe and nothing else.

Catatan implementasi

iSAR publishes one buffer and it is the stop level, not a direction. Which side SAR is on is not a buffer — you derive it by comparing the value against price, which is exactly what the template's Cross node does.
The Builder detects a flip as a Cross between a Price node and the SAR node. The price node's 'previous' value is the previous bar's close, not the previous tick, so the flip is evaluated bar to bar.
The template's trailing stop is a second, independent SAR. The psar trailing mode creates its own iSAR handle with its own step and maximum, so changing the entry SAR's settings does not move the trailing SAR unless you change both.
Counting how many bars ago the last flip happened, or how many flips occurred in a window, needs multi-bar state that the node palette does not express.

Bekerja paling baik / gunakan dengan hati-hati

Tidak ada indikator yang merupakan keunggulan universal. Inilah di mana SAR membantu — dan di mana ia menyesatkan.

Bekerja paling baik

Sustained, directional trends
As a trailing-stop rule rather than an entry
Higher timeframes where flips are rarer
Paired with something that says whether a trend exists

Gunakan dengan hati-hati

Ranges, where it flips on nearly every swing
As a standalone entry with no trend filter
Treating the dots as support or resistance
Raising step to 'make it faster' without re-testing

Gabungkan SAR dengan indikator lain

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

SAR + ADX

ADX > 25
Price crosses the SAR
Buy

Mengapa: Let a strength reading decide whether a trend exists at all before acting on a flip, because SAR flips just as confidently in a flat market as in a real move
Kondisi terbaik: Trending

Buat strategi ini →

SAR + Moving Average

Price above the MA
SAR flips below price
Buy

Mengapa: Take only the flips that agree with a slower directional read, which removes the counter-trend half of the reversals
Kondisi terbaik: Trending

No single-flow template pairs SAR with a moving average. Start from SAR Flip + ADX and swap the ADX condition for an MA node with a Compare against price, or add it as a third input to the And gate.

SAR + ATR

Price crosses the SAR
ATR sets the initial stop
Buy

Mengapa: Keep SAR for the exit and let volatility set the initial stop, so the first stop is not tighter than the instrument's normal bar range
Kondisi terbaik: Any

No single-flow template pairs SAR with ATR. Start from SAR Flip + ADX and add an ATR node feeding a risk-based lot or stop node — the Fractal Breakout + ATR template shows that wiring.

Parameter

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

Parameter	Default	Rentang uji yang disarankan	Fungsinya
Step	0.02	0.005–0.05	How much the acceleration factor grows each time the trend posts a new extreme. Larger values drag the stop in faster, so trends are cut shorter and flips happen more often. This is a rate, not a lookback window.
Maximum	0.2	0.1–0.5	The ceiling on the acceleration factor. It bounds how tight the stop can ever get, which matters most in long trends where the factor would otherwise keep climbing until the stop sits on top of price.
Shift	0	0–3	Which bar back the node reads the buffer from. Shift 1 evaluates against a fully closed bar. This is the node's read offset, not an argument to iSAR.

Preset awal

Patient 0.01 / 0.1 Wider stop, fewer flips, later exits

Standard 0.02 / 0.2 Wilder's original and MT5's default

Aggressive 0.04 / 0.4 Tight stop, many flips — usually too many

Contoh pasar

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

Berhasil

One flip, one long trend

SAR flips below price as a range resolves and the dots stay under price for the whole leg, tightening as the move extends — the case the indicator was designed for.

Gagal

Flipping every other bar

In a tight range price keeps touching the dots and SAR reverses repeatedly. Each flip is a full reversal in the classic system, which is why an unfiltered SAR bleeds in chop.

Difilter

Strength filter suppresses the flips

With a trend-strength condition attached, the same cluster of flips is ignored while the market goes nowhere, and only the flip that begins the real move is acted on.
