line indicator

[XXtrader]

is there a line or indicator that places line like 20 ticks under and over the current price and moves up and down dynamically?

I was able to get ChatGPT4 to whip this up real quick, I attached some photos of actual usage and here is the code...

IsOverlay = true;

AddPlot(Brushes.Orange, "UpperChannel");
AddPlot(Brushes.Blue, "LowerChannel");
}
}

protected override void OnBarUpdate()
{
if (CurrentBar < 1) return; // Make sure we have at least one bar worth of data.

double tickSize = Instrument.MasterInstrument.TickSize;
double upperBound = Closes[0][0] + 20 * tickSize; // 20 ticks above the last close price
double lowerBound = Closes[0][0] - 20 * tickSize; // 20 ticks below the last close price

Values[0][0] = upperBound;
Values[1][0] = lowerBound;
}
}
}
