Questions about supporting contract pairs and simultaneous reading

Hello everyone, thank you very much FMZ platform. If fmz can read two contract data at the same time, I don't think the documentation works.

1. I want to maintain a queue, inside of which is the last 24 minutes, full minute tick prices, plus the latest tick data.
2. I need two contracts to be read in at the same time, and fmz doesn't provide a combination of the two contracts to be read in at the same time.
3. Is fmz supporting full or partial pairs of contract transactions? If partial, where can you see the list of supported pairs?

Thank you very much!
