how to compare current stochastics to previous stoch

[john_robertson00]

I'm trying to compare the current Stochastics K to the previous one of 2 crosses.

something like this in code:

if stochastics K cross above stochastics D of current bar
&&
current stochastics K > stochastics K from the previous stochastics K cross above stochastics D

&&
Current price < previous price from when stochastics K cross above D

I'm also attaching a screenshot.

Any help is appreciated.
Thx.

Hi John, one idea would be working with an small array variable here to store what you need for your comparisons, consider this small snippet in your OnBarUpdate() to get started on this -

if (CurrentBar < 10) return;
			
if (CrossAbove(StochasticsFast(3, 14).K, StochasticsFast(3, 14).D, 1))
{
	pastCrosses[1] = pastCrosses[0];
	pastCrosses[0] = StochasticsFast(3, 14).K[0];
}
			
if (pastCrosses[0] > pastCrosses[1] && StochasticsFast(3, 14).D[0] < 30.0 && CrossAbove(StochasticsFast(3, 14).K, StochasticsFast(3, 14).D, 1))
         DrawDot("tag" + CurrentBar, true, 0, Low[0] - TickSize, Color.Blue);

( pastCrosses is defined as private double[] pastCrosses = new double[2]; )

Bertrand, thanks for the snippet. Let me give it a try and see how it goes.
Thx,

Hi Bertrand, that snippet worked good. Could someone tell me what am i doing wrong in trying this loop below: I'm trying to replace a OR OR OR condition with a loop, but it is not working:

Ugly code (see the many CCI(5)
#region Variables
private bool myFlag = false;

protected override void OnBarUpdate()
. post: from bertrand on: 10-16-2014, 02:47 AM has the if for pastCrosses section.
.
.
if (pastCrosses[0] > pastCrosses[1] && Stochastics(3, 8, 3).D[0] < 30.0
&& CrossAbove(Stochastics(3, 8, 3).K, Stochastics(3, 8, 3).D, 1))
&& ((CCI(5)[1] > 0) || (CCI(5)[2] > 0) || (CCI(5)[3] > 0)|| (CCI(5)[4] > 0)
|| (CCI(5)[5] > 0) || (CCI(5)[6] > 0) || (CCI(5)[7] > 0) || (CCI(5)[8] > 0)))


{
DrawDot("tag" + CurrentBar, true, 0, Low[0] - TickSize, Color.Blue);
}

========================
Better code:
========================
#region Variables
private bool myFlag = false;

protected override void OnBarUpdate()

if (pastCrosses[0] > pastCrosses[1] && Stochastics(3, 8, 3).D[0] < 30.0
&& CrossAbove(Stochastics(3, 8, 3).K, Stochastics(3, 8, 3).D, 1))

myFlag = false;
for (int i = 0; i < 8; i++)
{
if (CCI(5)[i] > 0){
myFlag = true;
break;
}
}

if (myFlag)

{
DrawDot("tag" + CurrentBar, true, 0, Low[0] - TickSize, Color.Blue);
}

John, looks as if you need to change your flag reset location, i.e. -

if (CrossAbove(Stochastics(3, 8, 3).K, Stochastics(3, 8, 3).D, 1)) 
		{
				
			for (int i = 0; i < 8; i++)
			{
				if (CCI(5)[i] > 0)
				{
					myFlag = true;
					break;
				}
			}
		}
			
		if (myFlag)
			DrawDot("tag" + CurrentBar, true, 0, Low[0] - TickSize, Color.Blue);
			
			myFlag = false;

Bertrand, you are the master. It works like a champ now. Thank you.
