📌 In this detailed guide, we’ll walk you through everything you need to know about the Stochastic Oscillator—from its definition and calculation to practical applications in real-world trading. Master this versatile tool and trade with greater precision and confidence.

🔍 What is the Stochastic Oscillator?

The Stochastic Oscillator is a momentum indicator that compares a security’s closing price to its price range over a specified time period.

• 📌
  Developed by: George Lane (1950s)
• 📌
  Purpose: To help traders detect overbought/oversold zones and anticipate reversals
• 📌
  Range: Oscillates between 0 and 100

🧮 How to Calculate the Stochastic Oscillator

The indicator is based on two main lines:

• %K Line (Fast Line)
• %D Line (Signal Line): 3-period simple moving average (SMA) of %K

📐 Formula:

%K = [(Current Close – Lowest Low) / (Highest High – Lowest Low)] × 100

📋 Definitions:

• Current Close: Latest closing price
• Lowest Low: Lowest price in the lookback period
• Highest High: Highest price in the lookback period
• Lookback Period: Typically 14 periods (can be adjusted)

💡 Example:

• Current Close = $50
• Highest High (14 days) = $55
• Lowest Low (14 days) = $45

%K = [($50 – $45) / ($55 – $45)] × 100 = 50
