Step 1
First, look at the line graphs of fast %K and fast %D and notice where the lines intersect. If those lines show too much volatility (many sharp peaks and valleys), then you can use the slow %K and slow %D lines, which are smoother.
-
Step 2
Now, look at the instances where the %K line crosses and rises above the %D line. This indicates point when you should buy the stock. And if you look at the instances where the %K line dips under the %D line, then this is a signal to sell.
What is the rationale for this method of stochastic interpretation? The %K line is above the %D line when the price is on the rise, and it lies below the %D line when the price is falling. And because stock traders aim to buy low and sell high, these crossings signal the appropriate time to buy or sell. -
Step 3
For another way to interpret the stochastic oscillations, observe when the %K and %D lines rise above .8 = 80% and dip below .2 = 20%.
When the %K and %D lines rise above 80%, many stock analysts recommend selling as soon as the lines dip back down below 80%. And when the %K and %D lines dip below 20%, analysts advise stock traders to buy once the lines rise above 20%. -
Step 4
To learn a third way of using a stochastic oscillator, first make a graph of each day's stock price and place that graph above the graph of %K and %D values.
-
Step 5
Now, look at divergences in the trend of the stock price versus the trend of the %K and %D lines.
When the price dips to a lower low, but at the same time the %K line has a higher low, this is a signal to buy. When the price rises to a higher high, but at the same time the %K line has a lower high, this is the point at which to sell.
