Bar == Unreliable unit

[FREEN]

As I understand, a bar closes only when a trade has occurred. Ie: a 1 min bar can be extended until a tick event. No matter how far or short that minute is extended, this makes a bar a unreliable unit.

Now, this wouldn´t be a acceptable in any cartesian system. It would rule out any vector, matrix and trigonometric calculations. Hence, in my opinion NT lack scientific quality.

I realize it might be an economists argument that a bar can´t be closed without an actual trade beeing made. However, after 5 years of NT use I´m stil conviced that it would be a superior behaviour to let a bar (empty from tick data), close (get it´s Y value) from the last tick, no matter when it occoured.

An x-axis unit MUST be reliable and predictable at all times!!!

[FREEN]

Ok, my whining here boils down to if the solution is reachable outside NT source code:

- Bars as scientificaly correct as any metric unit. (No need to dodge irratic behaviours at the x-axis).

- Bars closed at last tick price, no matter when it occoured. (The issue IF a trade really occoured in that bar is a much easier problem).

The above would open for use of vectors, trigonometry, matrices and any systematic link between Euclidean geometry and algebra.

Hello Freen,



I will forward your inquiry to the development team for consideration in a future release of NinjaTrader.


In NinjaTrader 7 and 8, you could create you own custom bar type that could suit your needs.



In NT 8, you could use the NinjaScript Editor to develop your custom Bar Type.
Below I have provided links to the NinjaTrader 8 Help Guide that details information about the methods and properties used in custom Bar Type development.

• • AddBar()
  • ApplyDefaultBasePeriodValue
  • ApplyDefaultValue
  • GetInitialLookBackDays()
  • GetPercentComplete()
  • Icon
  • IsRemoveLastBarSupported
  • OnDataPoint()
  • RemoveLastBar()
  • UpdateBar()

Here are links to our NinjaScript Editor, Educational Resources, Language Reference and User Help Guide to assist you further.
