Hello dear coders! I found an indicator on the net that is built according to the "Donchian channel" type. If you have time, take a look at it. Is it possible to change the color of the central line when the slope changes and, if possible, to add alerts and arrows when doing so. I am using it with a period of 68. It turns out quite an interesting picture. However, you can play with the parameters. For example, the Fibo number of 55 also looks interesting (faster reaction to price movement).
