Examples


// Prints the current upper value of a 20 period DonchianChannel using default price type double value = DonchianChannel(20).Upper[0]; Print("The current DonchianChannel upper value is " + value.ToString()); // Note the above call with a barsAgo of 0 includes the current Upper channel in the value. If we want to check for example for a break of this value, storing the last bar's channel value would be needed. double value = DonchianChannel(20).Upper[1]; if (High[0] > value) Draw.ArrowUp(this, CurrentBar.ToString(), true, 0, Low[0] - TickSize, Brushes.Blue);

// Prints the current upper value of a 20 period DonchianChannel using default price type
