Stochastic RSI
Overview
The Stochastic RSI applies the stochastic oscillator formula to RSI values rather than raw price data, creating a more sensitive momentum indicator that oscillates between zero and one. By measuring where the current RSI sits relative to its own range over a lookback period, the Stochastic RSI generates faster overbought and oversold signals than either the stochastic or RSI alone, making it particularly useful for timing entries within established trends.
Key Concepts
Stochastic RSI normalises RSI values to a zero-to-one range using the stochastic formula. Values above eighty percent are considered overbought and below twenty percent are oversold. The %K line is the raw Stochastic RSI and the %D line is its smoothed moving average. Crossovers between %K and %D generate entry and exit signals. The indicator is more volatile and generates more signals than traditional RSI. Stochastic RSI works best as a timing tool within a higher-timeframe trend context.
Entry Signals
Enter long when Stochastic RSI crosses above twenty percent from oversold territory in an uptrend. Enter short when Stochastic RSI crosses below eighty percent from overbought territory in a downtrend. Use %K crossing above %D in the oversold zone as a bullish timing signal. Confirm with price action at support or resistance for higher-probability entries.
Exit Signals
Exit long positions when Stochastic RSI enters overbought territory and %K crosses below %D. Exit short positions when Stochastic RSI enters oversold territory and %K crosses above %D. Close positions if the indicator churns in overbought or oversold territory without a clear cross. Use divergence between Stochastic RSI and price to anticipate exits.
Best Timeframes
5M, 15M, 1H, 4H
Pro Tips
Stochastic RSI is significantly more sensitive than regular RSI, which means it generates more signals but also more false signals. Always use it as a secondary timing tool after establishing trend direction from a higher timeframe — never trade Stochastic RSI signals against the prevailing trend. The default fourteen-period lookback can be adjusted to suit your trading style.

Keltner Channels
Keltner Channels are volatility-based envelopes plotted above and below an exponential moving average using the Average True Range. Unlike Bollinger Bands, which use standard deviation, Keltner Channels produce smoother bands that are less reactive to individual price spikes. This makes them effective for identifying trend direction, overbought/oversold conditions, and volatility squeeze setups when combined with Bollinger Bands.
Williams %R
Williams %R is a momentum oscillator developed by Larry Williams that measures the current closing price relative to the highest high over a specified lookback period. It ranges from 0 to -100, with readings above -20 indicating overbought conditions and readings below -80 indicating oversold conditions. Williams %R is closely related to the Stochastic oscillator but inverted, making it particularly responsive to price reversals.
Vortex Indicator
The Vortex Indicator consists of two oscillating lines — VI+ (positive trend movement) and VI- (negative trend movement) — that capture the directional movement of price through the relationship between the current high and prior low, and the current low and prior high. Crossovers between these lines signal trend changes and provide entry and exit timing for trend-following strategies across any market.
Ichimoku Cloud
The Ichimoku Kinko Hyo (Ichimoku Cloud) is a comprehensive indicator system that defines support and resistance, identifies trend direction, gauges momentum, and generates trading signals — all in a single glance. Developed by Goichi Hosoda, the system consists of five lines and a shaded cloud (Kumo) that projects into the future, providing a uniquely forward-looking view of market equilibrium.
