CUMULATIVE DELTA divergence indicator with the price

I want an indicator for mt5 that represents in a window below the price the cumulative delta drawn as in the example of image 1 attached: ie the delta candles drawn "graphically" based on the strength of the delta (cumulative delta in fact) and the candles that turn green with positive delta and red if the delta is negative.

the indicator must be able to choose the type of volumes that will draw the delta: real volumes (Bid / ASK) or tick volumes (Tick DIrection).

the indicator must recognize the divergences between the graph with the price and the cumulative delta as represented in image 2: i.e. the indicator must send a sound alert with an arrow on the graph, as a push notification, or as a telegram alert when the price records a new low while the cumulative delta does not break the previous low.

for the programmer: when you accept the work, specify the type of notifications you are able to provide to the indicator: that is, if you can only provide it with sound alerts and push notifications, or if you can add the alert in a telegram channel (not group) dedicated.

It is important that the indicator sends notifications on the divergence without redrawing: therefore not a notification that disappears afterwards but a notification that remains because it is sent only if it is certain.

the method with which there must be confirmation of the divergence between price and cumulative delta, I leave it to the programmer to choose. no matter which one he chooses, he will choose the most appropriate one (inversion pattern, closing of the candle, exhaustion of the volume due to a decrease in incoming contracts, pressure of buy / sell contracts that begin to load in the opposite direction, confirming the divergence, etc ... ), the important thing is that the alert does not come too late when the price has now fully retraced and it no longer makes sense to place a trade. if the notification arrives when the divergence is confirmed, but by now the inversion movement is already finished, obviously it is no longer of any use.

I know this is a complicated argument, but I rely on the experience and preparation of the programmer: the notification must occur quickly (not when the inversion movement has already finished), when a divergence occurs, it must be "certain, confirmed "and be notified immediately to allow the trader to open a position as soon as possible.

at the end of the job, the programmer has to give me the mq5 source file, not just the ex5 file.
