What is Stochastic Indicator and How it is calculated?
Stochastic is a momentum indicator which shows the strength of current trend. It does so by comparing current price to the range of prices within a definite lookback period. It is an oscillator and its value ranges from 0 to 100, hence it can also identify overbought and oversold price levels very accurately.
Stochastic Indicator was developed by George C Lane in 1950’s. According to an interview with Lane, the Stochastic Oscillator “doesn’t follow price, it doesn’t follow volume or anything like that. It follows the speed or the momentum of price. As a rule, the momentum changes direction before price.”
Stochastic Indicator is calulcated using below formula:
%K = (Current Close – Lowest Low)/(Highest High – Lowest Low) * 100
%D = 3-day SMA of %K
Lowest Low = lowest low for the look-back period
Highest High = highest high for the look-back period
The default look-back period is 14 days which can be changed depending on the security traded. Trading signals are generated when %K line of Stochastic crosses %D line.
Stochastic Divergances can also very accurately determine price reversals. Divergence occurs when the direction of the price trend and the direction of the indicator trend are moving in the opposite direction.
