I have a request for you.
Of course, I'm light years behind people like kvak, mrtools, xard777 and you.
And not even with chatGPT would I be able to do what I ask of you.
You have a wonderful indicator called v2vVWAP that is based on MIDAS (I'm devoted).
Wouldn't it be possible for there to be an alarm and phone notification when a candle crosses or/and touch the last outer/exterior/last lines and the central MIDAS Vwap???? You could do it?
Please
Best not to assume and even though it is April 1 this is not a joke.
write a VWAP indicator based on MIDAS that will send alerts and notifications when a line is crossed.

Here's an example code for an MT4 indicator that calculates the Volume Weighted Average Price (VWAP) based on the Market Interpretation/Data Analysis System (MIDAS) method and sends alerts and notifications when the VWAP line is crossed.

The indicator will calculate the VWAP based on the MIDAS method using the inputs provided (DayStartHour, DayEndHour, and PeriodsBack). The VWAP line is plotted as a blue line on the chart. The indicator will scan the historical data and send an alert and notification if the price crosses the VWAP line. The lastAlertTime variable is used to prevent multiple alerts from being sent for the same cross. The calculated VWAP value is also displayed in the alerts and notifications. The lastAlertTime variable is reset when the chart is refreshed.
