The VWAP and Volume Profile are already built into the Indicator library for NinjaTrader.  They are listed as Order Flow VWAP and Order Flow Volume Profile.  You MUST subscribe to the Order Flow Price Feed to access and use both of these indicators but it is money well spent, as I expect you will see as we ove on woith this training.

The VWAP indicator can be found at inside the free indicators offered by TradingView, and is called the Volume Weighted Average Price.

The Volume Profile indicator is one of the "Paid" options which you can access with the lowest priced subscription option ($14.95/month) and is found under the Indicators/Profiles tab of your TV platform.  Choose the Session Volume Profile HD from the various options offered. This version allows you to focus in specifically on individual price points when using the VP to locates lines of support and resistance.
