MultiTimeFrame issues

[zeller4]

Hello,
I'm attempting to make a multi-time frame stochastic indicator. I'm adding a second time series (10 minute in this case). I think it's successful when applied to certain time charts. However, I'm receiving error messages when applied to larger timeframes like 15 or 60 minute. I've used the

if (CurrentBars[0] < BarsRequired || CurrentBars[1] < BarsRequired...

but there's something else missing or incorrect.

=====================
Bars.BarsData.Period: 1 Min
BarsType: NinjaTrader.Data.MinuteBarsType
104: Error: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
at System.Collections.ArrayList.get_Item(Int32 index)
at NinjaTrader.Data.DataSeries.Set(Double value)
at NinjaTrader.Indicator.MTF_Stochastics_ChartControl _v02.OnBarUpdate()

I'm not aware how to modify the code to avoid this situation. If there's a way to make it a multiple of the chart on which it is applied, that is what I'm trying to achieve.
Any help you can give me is much appreciated.

Hello Zeller4,

Thank you for your post.

something in the code is calling an index value that is bigger than the actual size of the collection.

Like accessing 5 when there are only 4 objects in the collection.

You would want to run through some prints in the code to see where it might be breaking the script.

I've read the help section "standard answer" of why it happens. Unfortunately, it has to do with something about bars required, days loaded, or some way of checking higher time frames against added dataseries time frames... Do you have some specific help you could offer?

The problem might be here

if (CurrentBars[0] < BarsRequired || CurrentBars[1] < BarsRequired || CurrentBars[1] < per){
                Direction.Set(0);
                Signal.Set(0);
                DirectionMTF.Set(0);
                SignalMTF.Set(0);
                
                return;
            }

In some cases you try to set values when there are no bars.

Try

if (CurrentBars[0] < BarsRequired || CurrentBars[1] < BarsRequired || CurrentBars[1] < per){
                
                return;
            }

instead.

Thanks Harry,
Do you have a suggestion how or where I need to set these initial zero values then?

I would also change line 96:

_stoch = Stochastics(Closes[0], periodD, periodK, smooth);

If you wish to set values to the DataSeries objects, you need to check whether BarsInProgress == 0, so you could use the code

if (CurrentBars[0] < BarsRequired || CurrentBars[1] < BarsRequired || CurrentBars[1] < per){
                if(BarsInProgress == 0){
                   Direction.Set(0);
                   Signal.Set(0);
                   DirectionMTF.Set(0);
                   SignalMTF.Set(0);
                }
                return;
            }

In that case the value will only be set when there is a current bar of the first Bars object.
