The distance of price to the top boundary of the ribbon would form the positive histogram, and the distance of price to the lower boundary would form the negative histogram, and any price within the ribbon would be considered the zero line. What do you think?
It can be done
Here is a "zero line" version. You will notice that it is not interpolated when in mtf mode. It is because linear interpolation, when applied to this type of discontinued data, is simply not looking OK, so I left it out
Can I have this as MTF and also as Bars
TMA Centered & bands
Here is the multi time frame version (with some more options) : tmacentered_amp_bands_2.01_mtf.mq4
For bars version : do you mean color bars on a chart colored accordingly to the cenetered TMA slope changes?
Yes exactly! Thanks for the fast response.
Here is the bars version too : tmacentered_bars_mtf.mq4
First this one : auto_fib_pivots_nmc.mq4
The next is this one (it is upgraded with all the averages types so it has 20 types too). There is one warning message at compile time, but it should be ignored (it is completely benign - does not influence anything, and it would require adding unnecessary code on order to avoid that warning) : cci_study_2_nrp_amp_mtf_nmc.mq4
