Create an indicator based on price action and FVG on 15sec chart

create an indicator that displays the first presented FGV or imbalance after specific times of day and is on a 15sec chart. maximum number of 22 per day. all fvgs or imbalances should be based on a 15 sec chart and be also visible when a 1m 5m and 15m chart is opened. after creating the indicator an ea should be created too.

there should be 4 different groups (Asia, London, am, pm) per group max 6 fvgs. each group has different color, in each group you can select the different times (max 6)

display today, yesterday and day before -----> which one to show can be selected in inputs

create also ema 8 and ema 21

the ea should trade within the fvgs, when they are larger than 3 points on nq, more detailed requirements later.
