Interpretation of Stochastic Oscillator

Stochastic locates the area of the close relative to the high/low range over the selected number of periods. It is assumed that momentum changes direction before the price does.

Thus, Slow Stochastic plots bullish or bearish divergences with price movements as a warning of reversals. This indicator is also used to identify the bulls and bears or overbought and oversold conditions of the market.

Interpretation of Stochastic Oscillator

Slow Stochastic right at 50 signals a neutral bias, above 50 means the close is in the upper half of the range with upward momentum, below 50 indicates down momentum where the close is in the lower half of the range.

When Slow Stochastic over 80, it indicates that price is near the high of the range of the selected period and the condition is overbought if the market is ranging. On the other hand, below 20 indicates the price is near the low of the range of the selected period and the condition is oversold if the market is ranging.

Divergences: Price makes a lower low but Slow Stochastic makes a higher low at the same time plots bullish divergence and a bearish divergence occurs when price makes a higher high but Slow Stochastic makes a lower high over the same period.

Uses of Stochastic Oscillator

Buy in bullish momentum:

  • Stochastic value rises above 50 level
  • %K remains above the Slow Stochastic

Buy in bullish momentum

Stochastic value above 50 represents the bullish momentum of the market. %K holds above the Slow Stochastic adds an extra confirmation about the bullishness of the momentum. You may directly go for the buy entry once the conditions are met. Price breaks above its current range with Stochastic value above 50 represents buy opportunities with the bullish breakouts. Stochastic value reaches above 80 with %K below the Slow Stochastic means price reached its overbought condition and it is time to exit the buy entry.

Sell in bearish momentum:

  • Stochastic value moves below 50 level
  • %K goes below the Slow Stochastic

Sell in bearish momentum

This is a 15-minute AUD/USD (Australian Dollar vs US Dollar) chart. Initially, the market was moving sideway as the price was roaming within a short range. Later, we found a bearish bar that closes below the current range of the price.

At the same time, Stochastic value drops below the 50 level and %K moves below the Slow Stochastic representing an ideal sell opportunity within the bearish momentum of the market. Once all the confirmation is met, we put a sell entry right below the low of the respective large bearish bar. Stochastic value reaches below 20 levels and %K moves above the Slow Stochastic means market reaches its oversold condition and it is time to close the sell entry.

Trading directly based on bullish/bearish momentum signals from Stochastic Oscillator represents short-term trading opportunities thus, suits best as scalping and intraday trading strategies.

Swing trading using Stochastic Oscillator:

Stochastic Oscillator signals the overbought/oversold conditions of the market and uses its crossover signal to identify potential swing high or low of the market. For swing trading, traders aim to buy from the swing low and sell from the swing high of the market.

Buying from the swing low of the market:

  • Stochastic moves below its 20 level
  • %K moves above %D and bounces upwards from the oversold area

Buying from the swing low of the market

Remember, Stochastic value moves down to its oversold level doesn’t confirm the current price level as the swing low of the market. You must wait until %K crosses above the %D and both of them bounce upwards from its 20 levels.

Selling from the swing high of the market:

  • Stochastic value rises above the 80 level
  • %K moves below %D and bounces downwards from the overbought area

Selling from the swing high of the market

Stochastic value above 80 represents the basic signal of the overbought condition of the market. In such conditions, the price level should only be considered as the current swing high of the market when %K crosses below %D and starts to fall from the oversold level of the Stochastic Oscillator.

Swing trading is tricky but it allows the trader to achieve better profit margins compared to the risk involved with each trade entry. Thus, as a swing trader, you should target at least 1:2 risk to reward ratio while trading based on Stochastic Oscillator signals.
