Market data exchange

I'm from china. So I have chinese market stock & futures market historical trading data include tick, minutes etc. Now I want to COMEX historical tick data. I wish to exchange to you use my chinese market data. And I wish to update data aperiodically. Can you help me?

I don't have COMEX historical tick data but other member may share it with you.

Hey, I got Silver COMEX(SV) tick data and Im interesting in KOSPI 200 Futures (KM).

I don't think that one would be interested in exchanging as all of us have bought after making some planning and analysis. And chinese shares are having more fluctuations.
