Pinescript Indicator

Hi Developers,

This order is intended to code a pinescript similar to the following tradingview indicator: "first fvg @joshuuu"

The indicator has 3 sessions to select the time from. Only one session must be coded, keeping the ability to change the time, FVG Color, extend FVGs and Enable alerts, Please see below.

The FVGs in the chart from the new coded indicator must match the FVGs from the original Tradingview indicator, must be on the same candle and time, for the same session time

The General settings below, are not required .
