Price Channel Stop indicator

The Price Channel Stop custom indicator displays the current estimated trend based on the channel period and desired risk. Additionally, it presents two levels of values that can serve as stop-loss points for orders that have been opened based on this indicator.

Utilizing the indicator across three different periods (e.g., 20, 50, 200) and observing a change in trend color can serve as a signal for both opening new orders and closing orders that have already been initiated.
