Swing indicator

[TexFly]

Hello,

Is there a way of catching via code the first yellow dot of the swing indicator?

Basically when SwingLowBar or SwingHighBar start!

Thanks.

Hello,

SwingHighBar and SwingLowBar will return -1 when an occurrence has not been found within the lookback period.

Once an occurrence has been found, it will return a value of 0 for that bar. So you can check for a value of 0 and your condition should be satisfied:

			if(Swing(5).SwingHighBar(barsAgo, instance, lookBackPeriod) == 0)
			{
				//doSomething;
			}

Please let me know if you have additional questions.

Would you please be so kind to explain exactly what the three variables (int barsAgo, int instance, int lookBackPeriod) do in the swing method?

The documentation is not clear to me. I understand the "barsago"...

When I try
if(Swing(5).SwingLowBar(0, 1, 10) == 0)

I get no signals. If I do
if(Swing(5).SwingLowBar(0, 1, 10) > 0)

I get a signal for each bar!

High Bar
Swing(int strength).SwingHighBar(int barsAgo, int instance, int lookBackPeriod)
Swing(IDataSeries input, int strength).SwingHighBar(int barsAgo, int instance, int lookBackPeriod)

Low Bar
Swing(int strength).SwingLowBar(int barsAgo, int instance, int lookBackPeriod)
Swing(IDataSeries input, int strength).SwingLowBar(int barsAgo, int instance, int lookBackPeriod)


Thanks!

Sorry - the value that is being return will be equal to the swing strength, not 0 as I stated.

If you're using a swing strength of 5, then you would want to check for a value of 5.

Using an instance of 1, it will return the most current instance. Using 2 would give you the 2nd most recent instance.

The lookback tells how many bars it will look back to check for an occurrence.

You may want to visually draw the number being returned to visual how this will work

double hi = Swing(5).SwingHighBar(0, 1, 10);
			
DrawText("highbar" + CurrentBar, hi.ToString(), 0, Low[0], Color.Black);

Thanks for the reply. I'm still missing something. All I'm trying yo do is catching the dot shown in the picture below. I want to add an arrow when the first orange signal shows.

Thanks!

The Swing indicator plot repaints, so it is expected that indicator values and plot values will different.

The logic you're using to paint the DrawArrow in your indicator would not necessarily match the Swing indicator plot.

How do I match it? ;-)

How do I catch that first dot?

[NinjaTrader_Matthew]

The Swing indicator was designed as a visual tool. Since this indicator repaints, it would be hard to match it completely.

You may want to consider working with HighestBar() and LowestBar();

			int highestbar = HighestBar(High, 10);
			int lowestbar = LowestBar(Low, 10);
			
			if(lowestbar == 0)
			{
		
			DrawArrowUp("lowbar"+CurrentBar, false, lowestbar, Low[0], Color.Blue);
			}
			
			if(highestbar == 0)
			{
			DrawArrowDown("highlow"+CurrentBar, false, highestbar, High[0], Color.Red);
			}
