Output from Bars.TickCount includes strange bar details

[toughcookie]

I'm planning to use TickCount in a new indicator and I built a very simple test to check the output from TickCount.

The code in OnBarUpdate simply contains this:

protected override void OnBarUpdate()
{

Print(string.Format("Bar {0} The tick count of the current bar is {1} ", CurrentBar, Bars.TickCount.ToString()));
}

But when I run this on a 250 tick chart with Tick Replay enabled, I see the following output:

Bar 18979 The tick count of the current bar is 247
Bar 4744381 The tick count of the current bar is 1
Bar 18979 The tick count of the current bar is 248
Bar 4744382 The tick count of the current bar is 1
Bar 18979 The tick count of the current bar is 249
Bar 4744383 The tick count of the current bar is 1
Bar 18979 The tick count of the current bar is 250
Bar 4744384 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 1
Bar 4744385 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 2
Bar 4744386 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 3
Bar 4744387 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 4
Bar 4744388 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 5
Bar 4744389 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 6
Bar 4744390 The tick count of the current bar is 1
Bar 18980 The tick count of the current bar is 7
Bar 4744391 The tick count of the current bar is 1

Why do I see these strange bar numbers, all with a tick count of 1 on every alternate line?

Hello toughcookie,

Thank you for your inquiry.

In my testing with Tick Replay on a 1 minute ES 12-20 chart and , I don't see the same. Who is your data provider, and what instrument are you testing on?

Thanks in advance; I look forward to assisting you further.

Hello Kate,

My data provider is CQG. The chart I was testing on was ES 09-20, 250 tick. I ran Tick Counter on the same chart and it worked OK, so I'm sure it's something wrong in my indicator.

Hello Kate,
Sorry, my bad. I just noticed I had left an Add Data Series instruction in the State == State.Configure section for a 1 tick data series.
I removed that and it now works OK.
Sorry for wasting your time.
