Expert coders, I have attempted to add MTF and arrows to this three-state histogram which is a variant of Flat Trend, but I'm having no success. This indicator's alerts are working properly and it's useful in my strategy as a filter, though it would be more helpful visually if there were arrows on the price chart anytime the histo shows colored bars, for initial trend entry and even ongoing trend entry. This three-state histo shows black voids where price is unsure of trend direction, then shows colored bars when price moves directionally based on input settings. I find it quite useful for scalping M1 & M5 charts.

What I'd like to see is an arrow anytime the histo alerts a colored bar. In the case of several colored bars in a row, an arrow on just the first colored bar is desired. Then the histo might go dark depending on price action, and if the same color bars begin to display again, I'd like another arrow of the same indicated direction to appear. See my attached screenshot showing hand-drawn arrows to make the point - basically, I'd like arrows for any change in histo state except for neutral (black) areas. I just could not get this to code correctly myself. It would be most appreciated if the usual suite of arrow options were available - selectable wingding codes, arrow size, and distance / arrow color settings. MTF would be amazing to have in the code as well if it's not too hard for you to add (I tried but it wouldn't work). Many thanks!
