Day's Buy Sell Volume label

This indicator looks simple but it was bit tricky to code and to make it work on all time frames .
I have used array in this to showcase the use of array, array give you more flexibly.
It works on all time frame 1m 2m 3m 5m 10m 15m 30m 60m 120m.
When the time frame is greater than the or equal to "D" it will show the current bar volume only.

Total volume is made up of buying volume and selling volume. Buying volume is the number of shares, contracts, or lots that were associated with buying trades, and selling volume is the number that were associated with selling trades.

This indicator shows two labels green one is showing the buying volume of the current day and the red label is showing the selling volume of the current day.
I am making this code available to all.
This code is for Total volume is made up of buying volume and selling volume. Buying volume is the number of shares,
contracts, or lots that were associated with buying trades, and selling volume is the number that were associated with selling trades.
