MTF Trend Histogram

Hello coders,

I would like to make a MTF multi-lines histogram from a trend oscillator. I give the mq4 file of the original trend indicator. I would also need to understand clearly what this indicator calculates and what the parameters exactly correspond to.

The original indicator displays 2 curves, red for down trend and blue for up trend. I only need the histogram lines to display red if red value of the original indicator is above blue value, and vice versa, and allowing a third color if values are exactly the same. Parameters of the original indicator must be kept, so this job is the transformation of an already existing simple indicator.

Histogram must have from 1 up to 8 lines (number to be set in parameters) : 8 would be if all Timeframes M5 to MN are selected in parameters. The histogram(s) shall appear only on the smallest timeframe taken into consideration (if all 8 Timeframes are selected then histogram is visible only on M5). We don't take M1 into consideration. Higher Timeframes colors correspond to the dominant trend on last closed candle on these timeframes.

In addition I would like to be able to set different parameters for each timeframe separately : select distinct values as regard to the 6 original indicator's parameters, except for some parameters as the price type parameter for which it would seem more logical to keep the mode identical for all timeframes.

Regards
