Stochastic Oscillator
This tool for MetaTrader 4 is specifically engineered to streamline your trading operations. This technical indicator acts as a specialized analysis tool designed to visualize market data. It helps traders identify emerging trends, momentum shifts, and key support or resistance levels by plotting statistical calculations directly onto price charts.

Q: Do custom indicators slow down the platform? A: Too many complex indicators can impact performance; remove unused ones via the "Indicator List" (Ctrl+I).

Description & Settings
The Stochastic Oscillator Technical Indicator compares where a security’s price closed relative to its price range over a given time period.
The Stochastic Oscillator is displayed as two lines. The main line is called %K. The second line, called %D, is a Moving Average of %K. The %K line is usually displayed as a solid line and the %D line is usually displayed as a dotted line.
There are several ways to interpret a Stochastic Oscillator. Three popular methods include:
Buy when the Oscillator (either %K or %D) falls below a specific level (e.g., 20) and then rises above that level. Sell when the Oscillator rises above a specific level (e.g., 80) and then falls below that level;
Buy when the %K line rises above the %D line and sell when the %K line falls below the %D line;
Look for divergences. For instance: where prices are making a series of new highs and the Stochastic Oscillator is failing to surpass its previous highs.
Calculation
The Stochastic Oscillator has three variables:
%K periods (Pk). This is the number of time periods used in %K calculation. By default is 5;
%K Slowing Periods (Sk). This value controls the internal smoothing of %K. A value of 1 is considered a fast stochastic; a value of 3 is considered a slow stochastic. By default is 3;
%D periods (Pd). This is the number of time periods used when calculating a moving average of %K. By default is 3;
The formula for %K is:
%K = 100*SUM (CLOSE - MIN (LOW, Pk), Sk) / SUM (MAX (HIGH, Pk) - MIN (LOW, Pk)), Sk)
Where:
CLOSE — is today’s closing price;
MIN (LOW, Pk) — is the lowest low in Pk periods;
MAX (HIGH, Pk) — is the highest high in Pk periods;
SUM (CLOSE - MIN (LOW, Pk), Sk) — amount composed CLOSE - MIN (LOW, Pk) for period Sk;
SUM (MAX (HIGH, Pk) - MIN (LOW, Pk)), Sk) — amount composed HIGH (Pk)) - MIN (LOW, Pk) for period Sk.
The %D moving average is calculated according to the formula:
%D = SMA (%K, Pd)
where:
Pd — is the smoothing period for %K;
SMA — is the Simple Moving Average.
