What is Stochastic?

The Stochastic Oscillator measures where the most recent close sits relative to a selected lookback range. It produces values between 0 and 100.

What does it measure?

The position of the close within the recent trading range rather than the absolute amount of price change.

How is it calculated?

%K compares the latest close with the lookback low and high. %D is a smoothed average of %K.

Common interpretation.

  • High readings indicate that price is closing near the upper part of its recent range.
  • Low readings indicate closes near the lower part of the range.
  • Extreme readings can persist during strong trends.
  • %K and %D crossovers describe changes in short-term momentum.

How traders use it for market context.

  • Stochastic readings can provide additional context when futures are rotating inside a defined range.
  • Trend and session context remain important because oscillator extremes behave differently in directional markets.
