Indicators don't update intrabar - Realtime & Calculate OnPriceChange or Tick

[JGRtrader]

I have been struggling to find out why my code, Based on Hull or other Indicators, running Realtime, do not change value Intrabar with PriceChange or Tick Calculate. They only change value on IsFirstTickOfBar. Note: They do change between to different values sets on every other Update, but on NewBar (First Tick) the change is significant.

I have attached some Output data from one of my tests to show what I am talking about. I have included below the key code lines that create the data.
The Output data does include my Calculate and State (shows Realtime).

A factor seems to be the HUL calls WMA three times and WMA performs some of its calculations on on the First Tick of Bar. Close[0] Open[0] etc. do update with price.
Here is the code extracted from my Strategy that creates the variable recorded in Output.

// At Class Level
private HMA HullSlow; // Hull indicaor - Slowest period
private HMA HullFast; // Hull indicaor - Fastest period

// In DataLoaded
HullSlow = HMA(Close, SlowHullPeriod);
HullFast = HMA(Close, FastHullPeriod);

// In OnBarUpdate
ROCHullSlow[0] = HullSlow[0] - HullSlow[1];
FSHullDelta[0] = HullFast[0] - HullSlow[0];

(I have tried various permutations of the HMA (Hull) such as looking at one bar back on First Tick (which is recommended) but they have little effect other than pushing the results back in time)

Attached Ouput from my test print statements (Captured in PlayBack after change from Historical to Realtime). from my test print statements. Records 1 8-29-21.txt

It confuses me that the guides including SampleEnterOnceExitEveryTick (Using LinReg which also gates on First Tick) lead me to think that these indicator values do update Intrabar.

Hi JGRtrader, thanks for posting.

Please call Update() on your indicators on each OnBarUpdate call to ensure their OnBarUpdate method is called in sync e.g.

HullSlow.Update();
HullFast.Update();

//after this, the indicators will be up to date.

Kind regards,

VS did not like the construct you suggested. But I discovered after collecting and studying a lot of date with each OnBarUpdate that the indicator i am using HUL while it varies as a bar builds, it makes a bigger step change on the first tick of new bar. So the NT cross detect method generally does not fire until the 1st tick.

The HUL code shows three calls WMA in which some of the code only executes on first bar.

So I can't really use HUL for much during the build of bars but only at the beginning of a new bar. With 1000 bar chart say, this is a problem so I am figuring out another way to do what I want.
