NBarsUp 3 out of 5 were up?

[tickaway]

Hello,

I'm trying to figure out how to evaluate if any of the 3 of the bars in the last 5 were up with NBarsUp. Is that possible?


In the Ninjascript instructions it says "Period" parameter is for: Number of bars used in the calculation but I don't see an example of this.


Example is:

double value = NBarsUp(3, true, true, true)[0];

I assume [0] is for the current time frame? If it were [1] it would check another timeframe if existed?

Hello tickaway,

Thank you for writing in.

NBarsUp() does not take a period parameter. I will be reporting this so that period is removed from the help guide page for NBarsUp.

The barsAgo value [0] is not referring to a time frame. A [0] would denote the current value of the indicator, [1] the previous value, [2] the second previous value, so on and so forth.

I have created a simple example below to show how you can evaluate if at least 3 of the previous 5 bars were up bars. If this is true, draw a dot.

private int counter = 0;

protected override void OnBarUpdate()
{
	if (CurrentBar < 5)
		return;
	
	for (int i = 5; i > 0; i--)
		if (Close[i] > Open[i])
			counter++;

	// if our counter variable is more than or equal to 3, this denotes we've had at least 3 up bars in that 5 bar period we were looking over
	if (counter >= 3)
		DrawDot("Dot" + CurrentBar, true, 0, Close[0], Color.Green);
	
	counter = 0;
}

Please, let us know if we may be of further assistance.
