Here is an old school indicator by Mladen which may be of use to those who are browsing this thread - The Slingshot indicator for MT4.

From the archives, this the T3 TRIX ROC (Rate Of Change) Indicator for MT4 that was kindly coded and optimized by Mladen for MT4.

As explained by Mladen on TSD:

Upon searching I was surprised that we didn't have a standard Momentum Histogram uploaded yet so I'd better fill in that void by posting this one from the archives which was made by our dearest Mrtools back in the TSD days.

Of course, it still works perfectly. Thanks Mrtools!

As explained by Mrtools on TSD:

I couldn't find this one on our site yet so in case someone would like to try it here is the Velocity 2 Lines indicator for MT4 which was made by Mladen.

This indicator also comes with Arrows as well. Thanks Mladen.

This is an indicator I have always found intresting - The Momentum Of RSI MA for MT4 which was made by Mladen.
