The MTF RSI on RSI indicator is a useful and popular Forex trading tool for MT4. It is a free indicator that can be used to identify overbought and oversold conditions in the market. This indicator works by plotting the Relative Strength Index (RSI) of the current timeframe on the next higher timeframe. It then displays the RSI in a separate window, allowing traders to more easily identify potential entry and exit points. It is also a great tool for traders who want to stay on top of the market and make informed trading decisions.
