Can I change the AO periods?

Not through iAO. Unlike almost every other MT5 indicator, the Awesome Oscillator takes no period arguments — 5 and 34 on median price are part of its definition. If you need different windows you are building a custom indicator, or you can express the same idea with two moving-average nodes and a subtraction. The upside is that there is nothing here to overfit.

What does a green AO bar mean?

That this bar's value is higher than the previous bar's — momentum is increasing. It does not mean AO is positive. Green bars below zero happen constantly and mean downward momentum is easing. Sign and colour answer different questions, and confusing them reverses several of the classic rules.

They are close relatives. Both subtract a slow average from a fast one and draw the result around zero. The differences are that AO uses simple averages of median price with fixed 5/34 windows and no signal line, while MACD uses EMAs of a configurable applied price with a signal line. AO is the simpler, unconfigurable member of the family.

How do I trade a saucer or twin peaks?

Both are multi-bar patterns rather than single conditions — a saucer needs three bars on the same side of zero in a specific shape, and twin peaks needs two peaks with the second lower. They are readable by eye but need explicit state tracking in code, so they sit outside what the node palette expresses.

Can I build an AO EA without coding?

Yes for the zero cross and for bar-to-bar momentum. The AO + AMA template wires an AO node and a Constant zero into a Cross node, gated on an adaptive trend line. The pattern rules — saucer and twin peaks — are the exceptions and need custom MQL5.

How should I validate settings before going live?

There are no AO settings to optimise, which removes one source of overfitting but not the others — the filters, stops and targets around it are still fitted parameters. Backtest on quality tick data, then demo before risking money, and hold back data the search never saw when tuning anything that surrounds the signal.

Awesome Oscillator for MT5 traders

What AO tells you

AO compares the recent momentum of the market to its medium-term momentum by subtracting a slow average of the bar midpoint from a fast one. Above zero the short-term is leading; below zero it is lagging. There is nothing to configure, which removes a whole category of overfitting.

Above zero: short-term momentum leads the medium term
Below zero: it lags
The bar colour reports whether this bar is higher than the last, not the sign

1 Average median price over 5 bars
2 Average it over 34 bars
3 Subtract the slow from the fast

Mostrar la fórmula y detalles de cálculo

The Awesome Oscillator is a difference of two simple averages, computed on the midpoint of each bar:

Take the median price of each bar: MP = (High + Low) / 2.
Compute a 34-period simple moving average of MP, and a 5-period simple moving average of the same series.
Subtract: AO = SMA(MP, 5) − SMA(MP, 34).

The result is published on buffer 0 and drawn as a histogram. MT5 colours each bar by comparing it to the previous one — green when the value rose, red when it fell — which is a separate piece of information from whether the bar is above or below zero.

Every number in that calculation is fixed. iAO accepts only a symbol and a timeframe; there are no period arguments, no applied-price argument, and no signal line. That is unusual in MT5 and it is deliberate: Bill Williams designed AO as a single unambiguous reading of whether short-term momentum is leading or lagging the medium term, and there is nothing in it to tune.

In MQL5 the call is iAO(symbol, period) and it returns a handle to one buffer. Because the output is a raw price difference, its magnitude scales with the instrument — only the sign, the direction of change and the shape carry meaning from one symbol to another.

Notas de la plataforma

Función MQL5

iAO

Precio aplicado

Este indicador no recibe argumento de precio aplicado.

En el Builder

iAO takes no arguments beyond symbol and timeframe — not even a period. The 5 and 34 windows and the median-price input are fixed in the indicator's definition, so the Builder's AO node exposes only shift and timeframe.

Notas de implementación

iAO publishes one buffer and takes no parameters, so an AO rule is one node plus whatever comparison you need.
A zero-line cross needs something to cross against: the Builder's template supplies a Constant node set to 0 and feeds both into a Cross node.
The bar colour is not a buffer — it is derived from whether this bar is higher than the previous one, so an EA expresses it as two AO nodes at shift 0 and 1 with a Compare, not by reading a colour.
Saucer and twin-peak patterns need multi-bar state across three or more bars on the same side of zero, which the node palette does not express.

Combinar AO con otros indicadores

Un indicador raramente se sostiene solo. Estas combinaciones cubren los puntos ciegos de AO.

AO + Accelerator Oscillator

AO above zero
AC higher than the previous bar
Buy

Por qué: AC is this indicator with its own five-bar average subtracted, so it reports whether the momentum AO is measuring is still building. Requiring AO to be above zero before acting on a rising AC bar separates accelerating within an up move from accelerating out of a down one — the pairing Bill Williams intended
Mejor régimen: Trending

No single-flow template pairs them, though both nodes exist. Start from AC Acceleration + Pitch Trail and add an AO node with a Compare against a Constant of 0 into the same AND gate.

AO + AMA

AO crosses above zero
Price above the AMA
Buy

Por qué: Take the momentum flip only when the adaptive trend line agrees on direction, so a zero cross inside a range is ignored
Mejor régimen: Trending

Crear esta estrategia →

AO + Alligator

Lips crosses teeth
AO crosses zero
Buy

Por qué: Pair Bill Williams' momentum tool with his regime tool, which is how the two were designed to be read together
Mejor régimen: Trend start

No single-flow template pairs AO with the Alligator. Start from AO + AMA and swap the AMA condition for Alligator nodes into a Cross.

Abrir el Builder →

AO + Fractals

AO above zero
Price breaks the last fractal high
Buy

Por qué: Use momentum for the bias and the last swing level for the trigger, so entries happen at structure rather than at an arbitrary bar
Mejor régimen: Breakout

No single-flow template pairs AO with Fractals. Start from AO + AMA and add Fractals nodes with a Price node into a Cross.

Abrir el Builder →

AO + BW MFI

AO above zero
Index and volume both rising
Buy

Por qué: The other half of Bill Williams' bar-by-bar reading. AO says which way momentum points and over what horizon; the Market Facilitation Index says whether the single bar in front of you moved efficiently and whether anyone was in it. AO cannot tell a wide participated bar from a wide empty one, and the index cannot tell up from down — each supplies exactly what the other lacks
Mejor régimen: Trending

No single-flow template pairs the two. Start from BW MFI Green Bar and add an AO node with a Compare against a Constant of 0, feeding it into the AND tree in place of the Close-versus-Open pair.

Ejemplos de mercado

Dónde AO funciona, dónde falla y cómo un filtro cambia el resultado.

Funciona

Zero cross into a trend

AO crosses up through zero as a range resolves and stays positive for the whole leg — the clean momentum flip the template trades.

Falla

Zero cross in a range

In a flat market AO oscillates around zero and crosses repeatedly. Each cross is a trade with no move behind it.

Filtrado

Trend line filters the cross

With the adaptive average as a second condition, the same cluster of zero crossings is ignored while price goes nowhere.
