Post From: Replay accuracy of of large volume trade indicator

Hi,

I am trying to set up large order bubbles for NQ contracts highlighting buy or sell market orders by tick above 50 contracts. If I set the volume threshold to 50, I see only very few bubbles (which seems unrealistic to me + if I see a friends "deepcharts" chart, it shows significantly more bubbles)
For context: I'm using Sierra Charts delayed data feed (Service Package 5) for back-testing. What are the relevant settings to get the correct large order bubbles to spot absorptions etc.? I have the feeling the indicator does not correctly use the replayed time-and-sales data?
I have tried all available replay modes (e.g., calculate as real time, etc.)

Thank you in advance for the support!
