Convert Simple Script so that it Provides Data on Any Time Frame

Going to this link: https://www.earnforex.com/guides/forex-hourly-statistics-for-major-currency-pairs/

You can download a script (attached) that allows you to extract the volatility of any MT5 Symbol and show the Hour Breakdown in day.

Job Request:

I would like the ability to extract the volatility information on a more glandular level (i.e. lower timeframes than 1 Hour).

As a result I would like a Timeframe input added into the script which allows me to filter the number of bars represented in a day.

For example if I changed to the 15 Min, I would see the volatility of 96 bars (24 x 4) giving me a more detailed breakdown.

I may want to go more glandular than this, as a result I would like the TIMEFRAME input to be dynamic
