TradeStation Footprint heatmap

[psycandrew]

I was thinking of using the tradestation datafeed but the numbers in TSLA today for both footprint & heatmap do not match bookmap at all. Bookmap will say 5k shares went off and Motivewave will say 30k. It's a huge discrepancy.

Do you need tick data for Footprint & heatmap to work?
Does anyone know if TradeStation is providing tick data through their API now?

Thanks for your help.
