Asymmetric Stochastic Indicator

Related: stochastic multi-timeframe indicator - another powerful indicator for MetaTrader 5 traders.

The Asymmetric Stochastic Indicator is an advanced version of the traditional stochastic oscillator.

Also recommended: stochastic oscillator indicator for metatrader 5 - similar indicator with strong performance on MetaTrader 5.

The Kperiod now consists of two values - junior Kperiodshort (short) and senior Kperiodlong (long).

Oversold (OS) and overbought (OB) levels parameters are added. In case the stochastic enters OS/OB areas, Kperiods (lengths of highs/lows searching) are switched over.

The third difference is a Sens parameter, which allows cutting off oscillations below a certain limit set in points. This reduces the number of false signals. The standard stochastic locates the current price between price highs and lows for the number of bars set by the Kperiod parameter. The implementation of some limit allows cutting off oscillations that are inconsiderable for a trading system.

Behavior:
In case the stochastic enters the OS area, the indicator searches for lows at the bars junior Kperiod (Kperiodshort) and for highs - at the senior (Kperiodlong) one. In case the stochastic enters the OB area, lows are searched for at the long interval, while highs - at the short one.

Interpretation/Usage.
Entering OS/OB by the stochastic means switching a trend over to the appropriate direction. However, trend switching generally does not mean a signal for market entry according to the current trend direction. Position should be opened during a correction, which can be identified by 50% line crossing/touching. If you follow the turtle strategy, additions to your position should be made during corrections. When a trend is being switched over, positions should be closed completely or decreased. In the latter case, complete closing of a position is carried out during the correction, while a new position in the opposite direction is opened simultaneously. Stop levels are set near the previous (opposite) extreme point with a reasonable setback. But their triggering in the operating mode is unlikely. Stop levels are set there only for force majeure conditions.

This indicator was first implemented in MQL4 and published in 2026.

Indicator input parameters:
- Simple moving average;
- Exponential moving average;
- Smoothed moving average;
- Linear weighted moving average;
- JMA adaptive average;
- Ultralinear smoothing;
- Parabolic smoothing;
- Tillson's multiple exponential smoothing;
- Smoothing with the use of Tushar Chande's algorithm;
- Smoothing with the use of Perry Kaufman's algorithm.

It should be noted that phase type parameters for different smoothing algorithms have completely different meanings. For JMA, it is an external phase variable changing from -100 to +100. For T3, it is a smoothing ratio multiplied by 100 for better visualization, for Vidya, it is a CMO oscillator period, and for AMA, it is a slow EMA period. In other algorithms, these parameters do not affect smoothing. For AMA, the fast EMA period is a fixed value and is equal to 2 by default. The ratio of raising to the power is also equal to 2 for AMA.

The indicator uses SmoothAlgorithms.mqh library classes.
