• Relative Strength Index |

This indicator is also very popular with traders
in the future markets. Its formula is: RSI = 100 - ( 100/1+ rs ) Where rs = average of X day's up closes / average of X day's down closes. |

The number of days can be varied. In our case we choose
9 days instead of the usual 14 days. The RSI can also be calculated on a
weekly or monthly basis. The shorter the time, the more sensitive RSI becomes. The maximum and minimum levels that the RSI indicator can theoretically go to are 100 and 0. Usually if the RSI is above 70, it is overbought and if it is below 30, it is oversold. These are useful for short-term traders. An important use of RSI is when there is a divergence between the company's price or a market index and its RSI. A "bullish divergence" signals a short-term bottom while a 'bearish divergence" signals a short-term peak. |
