I'm trying to broaden my index future exposure, so I've been looking at European index futures. For DAX, ESTX50 and SMI, Interactive Brokers shows large volumes as I'd expect. But for other futures, the volumes are very small: in the hundreds per hour, at best: CAC40@MONEP ATXDE@DTB Hard to believe there's such low volume on these contracts. Am I doing something wrong? Also, for FTSE100 (Z), I can't subscribe to realtime market data. The Market Data Assistant only showed one "Pro" subscription. Do I need to claim I'm a professional trader to trade the FTSE100? Basically, I'm trying to map these futures into IB/TWS: https://uk.investing.com/indices/indices-futures The symbols from the "Specifications" tab on that page don't match IB's symbology.
