technical analysis question - rsi

  1. 1 Posts.
    Recently, I am learning RSI through this web site

    http://jstock.sourceforge.net/ma_indicator.html

    According to this web site, it states that, we should sell our stock when RSI is in high point. However, from the advice from my friend, he is advising that we shall sell our stock when RSI is in low point.

    May I know which statement is correct?

    Thanks!
