IsFirstTickOfBar with LineBreak barstype. Error

[cls71]

Hello,

It seems that the "IsFirstTickOfBar" instruction will not work correctly when it is used with the "LineBreak" bar type, and Calculate is not equal to Calculate.OnBarClose. It is running continually.

You can run the attached indicator in a chart with the next DataSeries configuration to check the bug. (set Calculate = Calculate.OnEachTick or Calculate.OnPriceChange).

Thanks

Hello cls71,

Are you testing over historical data or real-time data?

Are you getting no prints in either historical or real-time?

Or are you not getting a print on the first update of a bar when Calculate is On price change in real-time data only?

Or are you getting a print on every update of OnBarUpdate when you are only expecting 1 per bar?

Hello cls71,

Real-time data

Are you getting no prints in either historical or real-time?

In Historical I get 1 print for each bar (it is correct). In real-time I get a lot of prints.

Or are you not getting a print on the first update of a bar when Calculate is On price change in real-time data only?

Or are you getting a print on every update of OnBarUpdate when you are only expecting 1 per bar?

In real time when Calculate = Calculate.OnPriceChange, I am getting a print on every update of OnBarUpdate when I am only expecting 1 per bar.

Hello cls71,

I was able to research and find an answer on this.

The LineBreak bar calls RemoveLastBar() internally. IsFirstTickOfBar is true anytime RemoveLastBar is called.

From the help guide:
"If a bar type is set up to remove the last bar on a chart, IsFirstTickOfBar will automatically be set to True."

Below is a public link to the help guide.

https://ninjatrader.com/support/helpGuides/nt8/isfirsttickofbar.htm

This will also affect any other bar type (such as Renko bars) if and when it calls RemoveLastBar().

Thanks ChelseaB,

But then there is no solution in NT8?

Because in NT7 this error does not occur and it works fine.

Hello cls71,

I am not aware of a work around for this. RemoveLastBar() is a new concept for NinjaTrader 8.

I am happy to submit a feature request on your behalf for IsFirstTickOfBar to not be true when RemoveLastBar() is called if you would like.

Please note, it is up to the NinjaTrader Development to decide if a request will be implemented.

Hello cls71,

I've received tracking ID #SFT-3298 for your request that IsFirstTickOfBar is not set to true when RemoveLastBar() is called.

Please note it is up to the NinjaTrader Development to decide if or when any request will be implemented.

Thank you for your suggestion. Please let me know of any other requests you have for NinjaTrader.

Just for info, came across this when I just realised IsFirstTickOfBar is set to true permanently when using these bar types. Seems silly to me, but I guess some workaround with CurrentBar can be made.
