He didn't mention how many contracts he traded. So maybe it was a number bigger than 1. In order to make that much with one share of a stock, it would have to move $1500 in a day. Only BRK.A does that. Is that what you trade?
eMini had a 88 point range today or $4400 .............. on just 1 contract. Size of account and risk parameters is the only limit as to how many to trade.
I don't mean to be nosy or get into your private affairs, but well,.......What did he make in the market today? In regards to % trade return, and/or money return for his account? You can't start a post like this, and be private and conservative about the details of it all,
