$NIGHT This is the data my buddy found for me yesterday. It was too late last night, so we didn't discuss how to brush it. In fact, contract brushing trading competitions are much easier than spot trading.

You only need two accounts to hedge, one going long and the other going short. Together, the brushing essentially only incurs commission losses; both accounts can increase their trading volume.

If you want to discuss this with me, you can click on my avatar and join my chat room at the bottom of my homepage to discuss together.
