Relative Strength Index (RSI) = 100 – 100 / (1 + RS)

RS = Average Gain / Average Loss

To simplify the calculation explanation, RSI has been broken down into its basic components like RS, Average Gain and Average Loss.  This RSI calculation is based on 14 periods.  Losses are expressed as positive values, not negative values.

The very first calculations for average gain and average loss are simple 14-period averages.

  • First Average Gain = Sum of Gains over the past 14 periods / 14.
  • First Average Loss = Sum of Losses over the past 14 periods / 14

The second, and subsequent, calculations are based on the prior averages and the current gain loss:

  • Average Gain = [(previous Average Gain) x 13 + current Gain] / 14.
  • Average Loss = [(previous Average Loss) x 13 + current Loss] / 14.

If RSI of the stock is below 30  ie. 30-  can be interpreted as that the RSI is  indicating that stock is in the oversold or undervalued condition,  which is a signals of a trend reversal in the stock ie. stock is likely to move up and can be brought at current levels for swing trading. The chance of a bounce back is much higher in these stocks, 

So to sum up what is a good RSI number,  Stocks for which the RSI is approaching 30 are a clear buy on dips and if RSI has hit 70 it’s a clear signal to sell on rallies. We also advised traders  that if  there is a sell signal on the RSI chart, one needs to look for confirmation from other technical indicators for better gains . Only when other indicators suggest the bearishness,  they  should  short sell the stock in NSE market.
