VWAP - Volume Weighted Average Price

I need an indicator or adaptation of VWAP, which calculates the average of a specific time, example:

- VWAP of negotiations between 09.00 am and 11.00 am

- VWAP of negotiations between 10.00 am and 10.15 am

- VWAP of negotiations between 4:45 pm and 5:00 pm, etc.

The graphical time to be used will be the minimum (1 minute), that is, all the trades made in the period.

The indicator will calculate according to the instructions and plot the value obtained in the chart as a panel.

VWAP already exists monthly, weekly and daily, but I want an indicator that calculates only a specific time.

More details by chat.

Thanks
