Location of execution of trades.

[tk17]

For any stock I would like to find out where it mainly trades. Ex for stock ABC I would like to know that 50% of trades are executed on BATS, 30% on NASDAQ etc.
Is this information available? I have searched but not found anything.

For now I'm interested in USO but the question applies to any stock.
