For anyone interested here is a lightweight tool for plotting real-time and historical intraday RV values.

Short video on major features: bit.ly/rt-rv-v
This tool is provided for free for your convenience.
It is excel based and uses Interactive Brokers API for real-time data (follow instructions on download page).
Feel free to download and use it. It works completely independent of any chartaffair subscription.
However, if you happen to have a valid chartaffair premium subscription it will additionally produce up-to-date earnings data through the chartaffair API. The test key included will work for a few days from now.
The VBA code inside is 100% open and accessible and anyone wanting to is invited to modify and repost it (f.e. to add more brokers).
I can use the Tradehawk android app. However, it seems totally useless. It appears to be impossible to change the price of an existing order. Unlike with their browser interface Dash, you cannot select existing positions to close them. Next month I'm dropping Tradehawk and going back to using pure Tradier.
