Hi @imjustkaze,
Here’s a help page on the Order Flow Volume Profile indicator:
NinjaTrader Developer Community | NinjaScript Resources & Documentation
Do be aware thought that some other community members have reported issues with the Order Flow Volume Profile indicator that appeared in recent versions, which unfortunately for those that want to access the Order Flow Volume Profile indicator from code seem to be just about the same versions that currently support accessing the Order Flow Volume Profile indicator from code:
Once the community confirms that a new version of NinjaTrader no longer has the issues reported above, being able to access the Order Flow Volume Profile indicator from code sounds very promising!
