Plotting Draw.ArrowUp() w/ Historical Data

[robertmaierle]

I am trying to create an indicator that plots an up arrow below the bar if Low[0] < Low[1] && Close[0] > Low[1]. I have the indicator working, however it is only plotting the last instance where the above conditions are met. I would like it to plot all instances in the past where such conditions are met. Appreciate any help from those who know what I need to do to accomplish my goal. Thanks!!

Below is what I have so far
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Indicator here.";
Name = "MyCustomIndicator1";
Calculate = Calculate.OnBarClose;
IsOverlay = true;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
//Add your custom indicator logic here.
if (CurrentBar > 0)
{
if (Low[0] < Low[1] && Close[0] > Low[1])
{
Draw.ArrowUp(this,"", true, 0, Low[0] - TickSize,Brushes.Green);
}
}
}

I found the answer searching through other posts about plotting indicators. For those who find similar problems with custom script only plotting latest occurrence, you must add "+ CurrentBar" to the string tag argument.

example : Draw.Dot(this, "dotTag" + CurrentBar, true, ...)

hope somebody finds this helpful!
