CountIf Question

[trader3000a]

Hi,
I'm trying to use CrossAbove() within the CountIf function.
This is the example from the help files for CountIf:

// If in the last 10 bars we have had 8 up bars then go long
if (CountIf(() => Close[0] > Open[0], 10) > 8)
EnterLong();

I'm trying to do this:

if (CountIf(() => CrossAbove(Close, SMA(20), 1), 10) > 2)
{
Value[0] = 1;
Draw.Text(this, "ClusterYes" + CurrentBar, @"inflectionPoint", 0, (Low[0] + (-50 * TickSize)) );
}

it compiles, but I don't get any results
Any reason you can point to?
thanks,
David

Hello David,

Thanks for your post.

Just to make sure we are looking at this the same way, the Countif would be true if it finds greater than two crossaboves in the last 10 bars. The cross above is the close price crossing above the 20 period SMA.

Is that what you intended?

Hi Paul,
Yes, basically I'm looking for a yes/no answer to an excess of a threshold number of sma crosses within the last x bars.

here's an example of the event I'm looking to verify. you can see the cluster of blue and pink triangles where there was a relatively high frequency of sma crosses over a small number of bars. I'm trying to make a simple 1 or 0 heads-up indicator so that i can track this type of event over a number of instruments in the data analyzer

Hello David,

Thanks for your reply.

Please check your "Log" tab of the Ninjatrader control center and look for any error messages related.

I copied your code into an indicator and tested it by drawing a vertical line when the Countif condition was true. As you can see in the screenshot it seems to work as intended.

Hi Paul,

Thanks. We got it going. It looks like I omited the:

if (CurrentBar < 20) return;

I guess I don't really understand that piece yet.
Much apreciated!

David
