Stochastic Reversal

%K is the main Stochastic line showing where price closed relative to the recent range. %D is the signal line - a 3-period moving average of %K. Crossovers between %K and %D generate trading signals.

Use Slow Stochastic (14,3,3) for most trading. It smooths the %K line to reduce noise and false signals. Fast Stochastic is too choppy and generates many whipsaws.

Buy when Stochastic drops below 20 (oversold) AND %K crosses above %D (momentum shifting up). Both conditions must be met. Just being oversold isn't enough - wait for the crossover.

In strong downtrends, Stochastic can stay below 20 for extended periods - this is called a 'drop' pattern. Standard reversal signals don't work here. The trend is too strong.

Standard settings are (14,3,3) - 14-period lookback, 3-period %K smoothing, 3-period %D. This works for most daily chart trading. For faster signals, try (9,3,3).

Divergence is when price and Stochastic move in opposite directions. Bullish divergence: price makes lower low, Stochastic makes higher low (reversal up likely). Bearish divergence: price makes higher high, Stochastic makes lower high.

Pop: Stochastic stays above 80 for extended period = Strong uptrend (don't short; buy pullbacks). Drop: Stochastic stays below 20 for extended period = Strong downtrend (don't buy; short rallies).

Use a 50 or 200 MA. Only take oversold buys when price is above MA (uptrend). Only take overbought sells when price is below MA (downtrend). Or use ADX: trade reversals only when ADX < 25.

Common exits: When %K crosses back below %D (crossover exit), when Stochastic reaches 50-70 zone (neutral), or when Stochastic reaches opposite extreme (80+). Hybrid approach works well.

Use weekly Stochastic for major bias, daily for entry. Best long: Weekly oversold (< 30) + Daily %K crossing above %D. Full alignment = highest conviction.

Stochastic RSI applies the Stochastic formula to RSI values: ((RSI - Lowest RSI) / (Highest RSI - Lowest RSI)) × 100. It's more sensitive than either indicator alone and useful for short-term mean reversion.

In bull markets, Stochastic operates 40-100 with support at 40-50. In bear markets, it operates 0-60 with resistance at 50-60. Adjust your oversold/overbought levels based on the major trend.

Stochastic breadth = % of stocks with Stochastic > 50. Above 70% = broad bullish momentum. Below 40% = broad bearish. Use for market timing and exposure decisions.

Buy calls when Stochastic < 20 with bullish crossover (30-45 DTE, ATM). Sell bull put spreads at oversold crossovers. Exit when Stochastic reaches 50-70 or 50% profit.

Double Stochastic applies the Stochastic formula to Stochastic values themselves. This creates smoother readings that identify larger cycles. Useful for position traders.
