tradingview indicator -- 3

I need several indicators, which should contain the following 3 points: 1. Megavolume: I would like to see a triangle or something similar in the chart (preferably the symbol "V" if the daily chart shows a megavolume. A megavolume occurs when the traded volume on a day exceeds a record value within the last 26 weeks. The volume itself does not necessarily have to be shown separately. 2. Megabar: I would like to have a triangle or something similar in the chart (preferably the symbol "B" if a megabar appears on the daily chart. The megabar is the largest daily range calculated from the previous day's closing price (i.e. including the previous day's gap) within the last 26 Weeks The megabar can be increasing or decreasing 3. Reversal candle: As soon as a reversal candle appears, I would like to see a triangle or something similar (if possible, an “R” symbol) in the chart. A reversal candle is a candle in which the body represents 10% of the daily range. I must be able to edit the code further, so it must not be blocked. As soon as one of the 3 points occurs, an alert, SMS, e-mail should be sent. The indicators are to be applied to the following markets: Please watch: [login to view URL]
