During downtrends, draw trendlines connecting the lower lows on the stock and lower lows of the RSI. The buy triggers form on bounces back up through the 30 band and sell/sell short triggers form when RSI falls back under the 70 band. Strong uptrends can signal multiple bearish divergences before a material reversal may set in and vice versa on strong downtrends.

After you determine the value of the RS, you can apply the result in the first formula. A buy signal occurs when the RSI is previously below 50 and then rises back above 50. The default period setting for the Relative Strength Index (RSI) is 14 periods. A ratio of these two values is used to create a measure that moves between 0 and 100.

For example, imagine that on June 1 prices for a specific stock peaked at a value of $125 and RSI reaches 75.

If the average of U values is zero, both RS and RSI are also zero. If the average of U values equals the average of D values, the RS is 1 and RSI is 50. If the average of U values is maximal, so that the average of D values is zero, then the RS value diverges to infinity, while the RSI is 100. If the last close is the same as the previous, both U and D are zero. Can toggle the visibility of the Lower Band as well as sets the boundary, on the scale of 1-100, for the Lower Band (30 is the default).
