Currency Heatmap

I know that there are several heatmaps around but sat here with a few minutes to spare so decided to do my own.
(it is not necessarily very technical but hope it does what was intended).

Comments welcome on:

Ideas how to get any +ve benefit from it
How to use it.
Is it of any use?

What do the vertical bars represent, they are all the same size ?

They are not?
See attached.

Note: Just noticed there may be an error in the bar value calc so I need to check that when I get some time.

This is what I get.

The only way that should happen is if you have set all the timeframes to the same value.

I tried that and then changed 1 of them and the bars were not correct so that is why I say the calc may be wrong.

Must be referencing the wrong array value somewhere.
I will sort eventually but too busy right now.

Cuppa always helps ... it was not the arrays it was zeroing of the values in the wrong place!

Someone pointed out that the indi does not work for symbols that have a suffix.
(I never think about those)
Hopefully this should fix that.

Personally, I love using the heatmap on trading view.

I find it super easy to use and when I combine it with other confirmations, I find that it helps to add more weight, confidence and probability to each trading idea:
