N Bar Up/Down

[justinbourque81]

Hello,

I'm new to strategy building. I've got a strategy built with an issue that i'm stuck on...

Using N Bar Up/Down, I want to enter a position in the opposite direction once a certain number of consecutive bars are reached. (Example: buy after the 4th consecutive bar). The indicator triggers no problem with a 1 value that I can include in the strategy, but the problem is that it buys the 4th, 5th ,6th, 7th, etc consecutive bars also. So if im wrong and it goes past 4 to 8 consecutive bars, im wrong 4 times. How do I get the strategy to only buy the first bar after the N Bar (4) is triggered?? Screen shot attached.

Any help is appreciated!

Hello justinbourque81,
Thanks for your post.

You could implement a counter or a switch to essentially turn on/off your conditions for entry. Something similar to the following snippet would count 4 'signal bars', place an entry on the following bar, and then reset the counter to zero.

private int counter = 0;
protected override void OnBarUpdate()
{
	if (counter == 4)
	{
		//order entry here
		counter = 0;
	}
	
	if (counter < 4 && [COLOR="Green"]//your signal condition here//[/COLOR])
	{
		counter++;		
	}

}

Please let me know if you have any questions.

Thanks for getting back to me. I am really new to this as I mentioned. Im sure this is painful for you to explain such easy stuff to a rookie haha. So what you provided for me is intended to be an addition to the N up/down bar one I have already built or the counter will replace the N up/down bar indicator i am using?? Thanks, JB

Hello justinbourque81,

I see now that my sample was not as clear as it could have been. For most indicators my previous sample would be the correct way to accomplish this. I edited the original snippet to be more clear where your signal would go. After testing a little bit more; for the n Bars up/down indicators specifically it would be best to use the "switch" method though.
This is because the nBars up/down indicator is already doing the counting for us.

private bool mySwitch = true;
protected override void OnBarUpdate()
{
	double value = NBarsUp(4,true,true,true)[0];
	if (value==0 && mySwitch == false) 
	{
		mySwitch = true;
	}
	
	if (value==1 && mySwitch == true)
	{
		mySwitch = false;
		Value[0] = value;
	}
}

This snippet would only allow the first occurrence of NBarsUp after four consecutive up bars.

Please let me know if you have any questions.
