To follow what to do with charts, go to a free site www.stockcharts.com. Click on FREE CHARTS so you will have the 50-and 200-day moving average right on the chart plus some other stuff on there correctly.
Then scroll down to indicators and you should see the letters RSI and to the right the word ABOVE. Left click on the menu arrow and click on BELOW. Then go to the box that has NONE in it and left click and choose FULL STOCHASTIC and left click on it.
Next left click UPDATE and you should have three charts one below each other all under the main body of the chart.
