BarsType Trim & Merge

[aslane]

I would like to better understand BarsType functions TrimStart, TrimEnd, and Merge. When are they called? What are the purpose of those functions?

Hello aslane,

These are undocumented so I cannot provide any details about these.

From my understanding not NinjaScript tools intended for NinjaScript programmers to use.

This thread will remain open for any community members that are using unsupported manipulations of these properties that would like to share.

Well, if I have defined a BarType, will NinjaTrader call these functions? If so, under what circumstances?

I need to understand what the intention is, so I do not interfere with normal Ninja behavior.

Hello aslane,

To prevent interfering with NinjaTrader create your own variables with unique names, that do not use any names that are already used in the BarsType namespace or in the script class.

NinjaTrader does use these functions behind the scenes for string manipulation.
