Hey, 

if I change the settings to real volumes the indicator just disappears. Any ideas whats wrong?

Indicator is working based on real volumes correctly. But you must know real volumes are not accessible on all brokers. First make sure your broker provides this data.

Thank you very much for the education on this! Review has been edited. 

Hello, can you please install "draw in background" so that it is behind the chart? Thanks!

Hi, The ordering of objects on the chart are determined automatically to provide the best views. Some of them are in the background and some not.

If you want to send all to the back, please enable the option "Chart on foreground" on the chart properties window. If you do not have the desired results, send me details to check your problem.
