1. I could add asset filter.
2. Total number of tokens.
3. U can't, u r supposed to emulate matching algo and reconstructs trades according to order placement. I can add extra API calls if necessary.
Strange as for me. Maybe I do not understand how it should work and what does it. I figured it was something like an auction.
Ok, I'll look for a more detailed description.
Detailed description won't help. The only way to get recent trades is to emulate order matching from the very beginning. I'm going to add API for that.
