Mr. Tools, Kvak,
I kindly request you to convert the following TradingView indicator to MT4 and include support for all RSI types and averaging methods.
The indicator provides a normalized, non-linear momentum signal rather than relying on raw RSI values or simple RSI crossovers, which would be very useful for MT4 users seeking more accurate and noise-filtered momentum analysis. The histogram gives a clear bullish/bearish momentum bias that is easier to interpret than raw oscillators.
