swing candle

[brucelevy]

Hey guys I'm trying to identify the last down candle before a swing move up and the last up candle before a swing move down, any suggestions on how to incorporate that into the swing indicator

[brucelevy]

Here are the candles with arrows on the: https://gyazo.com/112adb72eca3b31c4723f68666297b8a

The indicator shows swings, here is the code:

/ Wizard generated variables
private int strength = 7; // Default setting for Strength
private int nbars = 10; // Default setting for Nbars
// User defined variables (add any user defined variables below)
private Color color1 = Color.Black;
private Color color2 = Color.Black;
private Color color3 = Color.Black;
private Color color4 = Color.Black;

private int lastHighBar ()
{
return Swing(strength).SwingHighBar(1,1,200);
}
private double lastHighBarValue ()
{
return Swing(strength).SwingHigh[strength+1];
}
private int lastLowBar ()
{
return Swing(strength).SwingLowBar(1,1,200);
}
private double lastLowBarValue ()
{
return Swing(strength).SwingLow[strength+1];
}
private double length ()
{
return lastHighBarValue() - lastLowBarValue();
}
private double curLength()
{
return lastHighBarValue() - MIN(Low,nbars)[0];
}
private double curLLength ()
{
return MAX(High,nbars)[0] - lastLowBarValue();
}

// plot below by replacing 'Close[0]' with your own formula.
if (CurrentBar < nbars)
return;

if (lastLowBar() > lastHighBar())
{
DrawLine("line" + CurrentBar,lastLowBar(),lastLowBarValue(),lastHigh Bar(),lastHighBarValue(),Color1);


}
if (lastLowBar() < lastHighBar() && Close[0] < lastHighBarValue())
{
DrawLine("line2" + CurrentBar,lastHighBar(),lastHighBarValue(),lastLo wBar(),lastLowBarValue(),Color2);

}
if (lastLowBar() > lastHighBar() && GetCurrentAsk() < lastHighBarValue())
{
DrawLine("line3", lastHighBar(),lastHighBarValue(),LowestBar(Low,10) ,MIN(Low,10)[0],Color3);

}
else if (lastLowBar() <lastHighBar() && GetCurrentAsk() > lastHighBarValue())
{
DrawLine("line4", lastLowBar(),lastLowBarValue(),HighestBar(High,10) ,MAX(High,10)[0],Color4);

}

Hello brucelevy,

My suggestion would be to make an array. Each time there is a new swing, record the bar number of the bar that the swing started on to the array. Then you can loop through the array and find all of the bars that a swing began on.

Just a heads up, the Swing indicator actually goes back in time and sets plots. This means you may need to monitor through the last few bars to detect the swing.

I'm trying to use something like this to draw a rectangle going forward on all the current and prior swing highs and lows, specifically on the candle before the swing started. For swing lows the rectangle should go from the prior candles high to the open, and for a swing high a rectangle from the prior candles low to open. It looks like the best indicator to modify is the swing indicator but I can't seem to get it right.

DrawRectangle("tag1", -20,Low[1],0,Open[1], Color.Black);

Hi brucelevy,

DrawRectangle("tag1", -20,Low[1],0,Open[1], Color.Black);

There is a negative bars ago index being used here. This would push the rectangle forward into the blank space in front of the chart.

Are you trying to draw a rectangle from 20 bars ago to the current bar?
Use a 20 for 20 bars ago.

If you record the bar numbers of each swing, or just the start of the last swing if you want (or the bar before it if you want), you can use CurrentBar-thatBarsNumber to find how many bars ago this was.

For example:
In Initialize():
private int swingStart = 0;

In OnBarUpdate():
if (/* conditions to detect start of swing here */)
{
swingStart = CurrentBar;
}
if (swingStart > 0)
{
int barsAgo = CurrentBar-swingStart;
DrawRectangle("rectangle", barsAgo, High[barsAgo], 0, Low[barsAgo], Color.Blue);
}
