Stopping indicator calculating before latest bar

[arbuthnot]

Hi guys

When you insert this code:

if(CurrentBar < 10)
            {return;}

the indicator isn't calculated for the first 10 bars of the chart.

However, I'm working on something which is not a conventional indicator but I need the calculations to stop 10 bars from now, i.e. from the right of the chart.

I'd be very grateful for any advice about what the equivalent of the above code is in order to achieve this.

Thanks in advance.

something like this for a single session ?

 
if(CurrentBar > Bars.BarsSinceSession - 10 )
return;

Hello arbuthnot,

It may be easier to just reference the bar values of 10 bars ago instead of trying to Stop OnBarUpdate from being calculated. For example:

Print("The value of the Close 10 bars ago is "+Close[10]);

That way all of your calculations will be based on the values 10 bars back. You may see the following thread for more references.

Much obliged, JC, for your idea. I followed your methodology and I certainly got some results! But, of necessity, the results are each delayed by 10 bars. So how to get round this?

What I did was create another indicator whose purpose is to shift the results back, as it were, by roughly doing as follows:

result = IndicatorName(10).Plot0[-10];

The negative in the [...] does the trick.

And thanks, Marco, for your suggestion. I'd actually tried using Bars.BarsSinceSession but it just doesn't seem to work - although it should! I must have left out something essential...

Not quite. A negative index on a Plot is appropos of nothing. It is pegged to 0. What you are plotting is the same as plotting the current value. If you want to Plot a past value, you need to use a positive index.

How do you mean you want to get around the delay? If you ask to Plot the value 10 bars ago, then it IS the same as asking for a 10-bar delay. Did I misunderstand the question?
