Stochastic Oscillator
Stochastic
The Stochastic Oscillator shows where the close sits inside the recent high–low range, on a bounded 0–100 scale. It reacts faster than RSI and carries its own signal line, which makes both level rules and crossover rules straightforward to wire into a no-code EA.

- Common levels

What Stochastic tells you
Stochastic asks a narrow question: within the last K bars, did this bar close near the top of the range or near the bottom? A reading near 100 means closes are clustering at the highs, which is a statement about persistence, not about a reversal being due.
- Above 80: closes are pinned near the top of the range
- Below 20: closes are pinned near the bottom
- %K crossing %D marks the moment that pressure changes hands
- 1 Find the high–low range of the last K bars
- 2 Locate the close inside that range
- 3 Smooth to get %K, then average it to get %D
공식 및 계산 세부 정보 표시
Stochastic locates the close inside a recent range and then smooths the result twice:
- Over the last K bars, find the highest high and the lowest low.
- Express the current close as a percentage of that range:
raw %K = 100 × (Close − Lowest Low) / (Highest High − Lowest Low). A close at the top of the range gives 100, at the bottom gives 0. - Apply the slowing average to raw %K. The result is MAIN_LINE, buffer 0 — what MT5 draws as %K.
- Average %K over the D period to get SIGNAL_LINE, buffer 1 — the dotted %D line.
Because the denominator is the range itself, the reading is bounded to 0–100 and adapts automatically to volatility: the same 40-pip move gives a different number in a wide range than in a narrow one. That is also the indicator’s weakness — in a strong trend the range keeps shifting with price, so the close stays near the top and the reading stays pinned.
In MQL5 the call is iStochastic(symbol, period, Kperiod, Dperiod, slowing, ma_method, price_field). Note the last argument: it is a ENUM_STO_PRICE field selector (STO_LOWHIGH or STO_CLOSECLOSE), not an ENUM_APPLIED_PRICE. George Lane popularised the oscillator in the 1950s.

Stochastic을 다른 지표와 결합
하나의 지표만으로는 충분하지 않습니다. 이 조합들이 Stochastic의 취약점을 보완합니다.
Stochastic + Bollinger Bands
- %K < 20
- Price at lower band
- Buy
Stochastic + ADX
- ADX < 20
- %K < 20
- Buy
No single-flow template pairs Stochastic with ADX. Start from Stochastic + Bollinger and add an ADX node with a Compare below 20 into the And gate.
Builder 열기 →Stochastic + Moving Average
- Price > MA
- %K crosses up through 20
- Buy
No single-flow template pairs Stochastic with a moving average. Add an MA node and a Price node into a Compare, gated with And ahead of the entry.
Builder 열기 →Stochastic + RVI
- %K < 20
- RVI main crosses above signal
- Buy
No single-flow template pairs them. Start from Stochastic + Bollinger and replace the band condition with two RVI nodes at the same period — one set to Main, one to Signal — joined by a Cross.
Builder 열기 →매개변수
자신의 통화쌍과 시간 프레임에서 검증할 초기값 — 보장된 설정이 아닙니다.
| 매개변수 | 기본값 | 권장 테스트 범위 | 기능 |
|---|---|---|---|
| %K period | 5 | 5–21 | How many bars the high–low range is measured over. The MT5 default of 5 is fast; 14 is the common slower alternative. |
| %D period | 3 | 3–9 | Averaging period that turns %K into the signal line. Larger means later but cleaner crossovers. |
| Slowing | 3 | 1–5 | Extra smoothing applied to %K before %D is taken. Slowing 1 is the 'fast' stochastic; 3 is MT5's default and is what most people mean by the indicator. |
| Overbought / Oversold | 80 / 20 | 70–90 / 10–30 | Your levels, not indicator inputs — iStochastic has no threshold argument. Move them together unless you deliberately want an asymmetric rule. |

시장 예시
Stochastic이 작동하는 곳, 실패하는 곳, 그리고 필터가 결과를 어떻게 바꾸는지.
Fade in a range
In a sideways market %K drops under 20 while price sits at the lower band, and the move back toward the middle plays out — the case the template describes.
Pinned in a trend
In a strong move %K sits above 80 for bar after bar. Selling each overbought print fights the trend and pays the spread every time.
Filtered by regime
Add a trend-strength filter and the same run of extremes is ignored while price keeps trending — the filter is what makes a fade survivable.
FAQ
- What is the difference between fast and slow stochastic?
- Slowing. With slowing set to 1 you get the raw %K — the 'fast' stochastic, which is very noisy. MT5's default of 3 smooths %K before %D is taken, which is what most traders mean by 'the' stochastic. There is no separate indicator; it is one parameter.
- Stochastic or RSI — which should I use?
- They measure different things. RSI compares the size of gains to losses; Stochastic compares the close to the recent high–low range. Stochastic reacts faster and gives more signals, which helps in ranges and hurts in trends. Neither replaces the other, and using both usually just gives you two versions of the same opinion.
- Why does Stochastic stay pinned at 80 for so long?
- Because in a trend the close genuinely keeps landing near the top of the range — that is what the indicator is reporting, and it is correct. Reading a pinned oscillator as 'due for a reversal' inverts what it says. Pair it with a regime filter before fading anything.
- Does Stochastic have an applied-price setting?
- Not in the usual sense. iStochastic takes a price-field selector instead: STO_LOWHIGH uses highs and lows, STO_CLOSECLOSE uses closes only. It also takes an ENUM_MA_METHOD for the smoothing. MT5's default, and the Builder's, is STO_LOWHIGH.
- Can I build a Stochastic EA without coding?
- Yes for level rules, %K/%D crossovers and centreline crosses — all three are a Stochastic node plus a Compare or Cross node, with periods and levels exposed as EA inputs. Divergence is the exception: it needs multi-bar swing detection the node palette does not cover.
- 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.
