NBarsDown not working properly.

[vkn2220]

Hi,

I am trying to plot an indicator with NBarsDown.
If previous 2 consecutive bars are down and current bar is up then it should print a dot on the current bar.
I am using the following syntax:

pullBack = NBarsDown (2,true,false,false)[1];
if (Close [0] > Open [0])
{
if (pullBack == 1)
{
DrawDot ("BuySign" + CurrentBar,false, 0, Low[0],Color.Green);
}
}

This code works at one place but not at other which is strange. Can someone explain if I am missing something here?

Thanks
Vinay

Hello Vinay,

Thank you for reporting the behavior.

I created a script and added prints to demonstrate the behavior.

(This can be very helpful when trying to understand the cause of a behavior. Below is a link to a forum post that demonstrates.

I've reported this and I will be looking further into it.

Hello Vinay,

Thank you for your patience.

I've got more information for you now.

The NBarsDown is looking for consecutive lower closes.

This means that if we are looking a span of 2 bars, both bars need to have the close less than the bar before it.

So with an offset of 1 bar ago, this would require the previous bar's close to be less than the close of 2 bars ago, and the close of 2 bars ago must be less than the close of 3 bars ago.

The print condition would look like this:

if (Close[1] < Close[2] && Close[2] < Close[3] && Close[2] < Open[2] && Close[1] < Open[1])
	Print(string.Format("{0} | condition set 1", Time[0]));
