Is anybody aware of Java/C++/Python API's available to retail ASX traders for market depth? I'm currently using IB which is ok but has a number of limitations / issues - the one I care most about is the limit of 3 simultaneous market depth subscriptions. Really I need at least 10 and preferably 20 or more - with IB I can get up to 10 by paying but it adds up and I'd prefer something a bit more reliable if I'm paying that much.

I found Spark Iguana 2 but when I sent them an email requesting pricing they never replied.. not exactly the best first impression but if they're good I'd be interested. https://iguana2.com/spark-sdk

Would appreciate any insight into anything else that might be available (either ASX specific or global but with proper ASX support).

Cheers
