Creating a running total

[Jeddy197]

Hi,

I feel like I've spent the past few hours on what is probably an easy fix. I'm trying to create a running total (cumulative) of (Close[0] - Close[1]).

So if...

(Close[0] - Close[1]) = 0.1

...new bar...

(Close[0] - Close[1]) (+ 0.1) = 0.6

...new bar...

(Close[0] - Close[1]) (+ 0.6) = 0.9


Thanks for any help,
James

Hello,

Thank you for the question.

If you are simply trying to accumulate the value, you would need to use a variable. Here is a simple example:

double accumulatedTotal = 0;
		
protected override void OnBarUpdate()
{
	if(CurrentBar > 0)
	{
            accumulatedTotal += (Close[0] - Close[1]);
	}
}

This would add the Close[0] - Close[1] to the existing value of accumulatedTotal .

I look forward to being of further assistance.

That's a great suggestion, Jesse. I didn't know about the

+=

way of achieving this.

James, I'm not sure if you want the sum of the actual (pos or neg) values or the 'absolute' value.

There may be a simpler way of proceeding. If you want the 'actual' going back to bar[3], say, then:

Close[0] [COLOR="Red"]- Close[1] + Close[1][/COLOR][COLOR="Blue"] - Close[2] + Close[2][/COLOR] - Close[3] = [B]Close[0] - Close[3][/B]

so you only need

[B][B]Close[0] - Close[3][/B][/B]

and you don't need a variable as the other values cancel out.

If you want to sum the absolute values, then change to:

{
            accumulatedTotal += [B]Math.Abs[/B]( (Close[0] - Close[1]) );
}
