Cross above/below methods confusion...

[Art09]

Hi,
I'm confused with above/bolow methods... If I want to write simple logic - if %K crossing 20% from below up, e.g. when %K is above 20% line (or %K = 21%) then put marker and/or alert... what method should I use CrossAbove() or CrossBelow() in this case? How to stop alerts and markers when %K is more 21, e.g. %K>=22 ? Same when the %K crossing 80% from above down, e.g. when below 80% or %K= 79 then put marker/alert... Stop when %K <= 78...
Here's what I'm actually writing and getting no signals/alerts...

If (K[0] > 80)
{
If CrossBelow(K, 80, 1) //If above 80 and crossing down, e.g. below 80% line...
{
// Then marker/alert short
}
}
Else If (K[0] < 20)
{
If CrossAbove(K, 20, 1) //If below 20 and crossing up, e.g. above 20% line...
{
// Then marker/alert long
}
}
....
Is there any other way to write this simple logic?
Thank you very much.

Hello Art09,

I would take a look at this help guide article on defining crossover conditions in the condition builder. You can setup crossing conditions in a point and click interface and then view the code for it.

Thank you. But I'm still not clear how to create strategy for Stoch. when %K crosses %D. This is what I get and I do not think this is correct:

if (CrossAbove(Stochastics(D, K, Smooth).DUpper, Stochastics(D, K, Smooth).DUpper, 1))
{
DrawArrowUp("My up arrow" + CurrentBar, false, 0, 0, Color.Lime);
}

With MAs it is clear and easy. But not when Stoch crosses the Stoch as above. What's the DUpper argument? Should I replace one of those with KUpper? Still confusing and not answers my question.
Thank you.

You would need to select the correct plot of the Stochastics to use, as they 'expose' 2 to use (%K and %D) - http://www.ninjatrader-support.com/H...ndicators.html

In your example you used the %D in both cases which is not the condition you seek.
