Draw.Arrowup/ArrowDown Error

[binzel]

Hey guys, novice here I thought I would start with a basic project of creating a RSI Divergence indicator, but I just cannot get past this Draw Error, It feels like I am doing it right but I have no doubt I am missing something obvious.

Thanks in Advance.

Here is my code:

using System;
using System.Windows.Media;
using NinjaTrader.NinjaScript.Indicators;
using NinjaTrader.Cbi;
using NinjaTrader.Gui.Tools;
using NinjaTrader.NinjaScript;
using NinjaTrader.NinjaScript.Strategies;

public class MyRSIDivergenceIndicator : Indicator
{
private RSI rsiIndicator;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = "Detects bullish and bearish RSI divergences.";
Name = "MyRSIDivergenceIndicator";
Calculate = Calculate.OnBarClose;
IsOverlay = false;
AddPlot(Brushes.Orange, "RSIDivergencePlot");
}
else if (State == State.DataLoaded)
{
rsiIndicator = RSI(13, 3);
}
}
protected override void OnBarUpdate()
{
if (CurrentBar < 50) return; // Ensure there are enough bars to perform the analysis

// Use Draw.ArrowUp to indicate bullish divergences
if (IsBullishDivergence())
{
Draw.ArrowUp(this, "BullDiv" + CurrentBar, 0, Low[0] - (2 * TickSize), Brushes.Green);
}

// Use Draw.ArrowDown to indicate bearish divergences
if (IsBearishDivergence())
{
Draw.ArrowDown(this, "BearDiv" + CurrentBar, 0, High[0] + (2 * TickSize), Brushes.Red);
}
}

private bool IsBullishDivergence()
{
int lookBackPeriod = 50; // Maximum look-back period
int minimumLookBack = 5; // Minimum look-back period

double lowestLowPrice = double.MaxValue;
double lowestRSI = double.MaxValue;
int lowestLowIndex = -1;

for (int i = minimumLookBack; i <= lookBackPeriod; i++)

Hello binzel,

May I confirm you created this script with the NinjaScript Editor by right-clicking the Indicators folder and selecting New Indicator?

Have you modified the using statements that are added by default?

(Try creating a new script and copying all of the using statements at the top to your script)
