Eliminate Multiple arrows in the same bar

[set2win]

Hi, I created an Indicator that when a certain condition was met, it would draw an arrow. I actually have had this happen in a couple of cases where I have created an indicator to draw arrow, where it draws 1, 2, 3 4 ,5 arrows on the same bar when the condition is met.
Here is a snippet of the code, in the OnBarUpdate section: Note Bars in Progress 1 is a 144 tick dataseries
protected override void OnBarUpdate()
{
if(CurrentBar < 21) return;
if (BarsInProgress == 1)
{

if (AuHMA1.Trend[0] == 1 && AuHMA1.Trend[1] != 1 && AuLinReg1.Trend[0] == 1 )
{

UpArrow[0] =1;
if (BarsInProgress == 0) entryBar = CurrentBar;
}
else UpArrow[0] =0;


if (AuHMA1.Trend[0] == -1 && AuHMA1.Trend[1] != -1 && AuLinReg1.Trend[0] ==-1 && CurrentBar != entryBar)
{
DownArrow[0] = 1;
//Draw.ArrowDown(this, "ARROWDOWN" + CurrentBar, false, 0, High[0]+TickSize*1, long_Exit_Color);
if (BarsInProgress == 0) entryBar = CurrentBar;
}
else DownArrow[0] =0;


}

/// Bars in progress is 0 for this code
if (UpArrow[0] == 1 && UpArrow[1] == 0 && CurrentBar != entryBar) Draw.ArrowUp(this, "ARROWUP" + CurrentBar, false, 0, Low[0]-TickSize*1, long_Entry_Color);
if (DownArrow[0] == 1 && DownArrow[1] == 0 && CurrentBar != entryBar ) Draw.ArrowDown(this, "ARROWDOWN" + CurrentBar, false, 0, High[0]+TickSize*1, long_Exit_Color);

}

Trying to figure out how to eliminate the multiple arrows to just one?

hi set2win,

apparently arrows are drawn every 144tick series is called,
so probably playing with the tag name could help, how about CurrentBars[0] in the tag name ?
Draw.ArrowDown(this, "ARROWDOWN" + CurrentBars[0], false, 0, High[0]+TickSize*1, long_Exit_Color);
does it do the trick ?

Thks, Amedeus, that worked!
