$BOB Don't open a bob contract. If you are optimistic about bob, take spot. Through professional technical observation, I have found that this project will accurately blow up long orders. If you don't go long, the dealer can't go short. If you unite and only buy spot, he can't smash the market. Recently, millions of dollars were blown up, which should have flowed into spot, but you played the contract, and the dealer controlled the spot blow-up contract. Remember, only buy spot.
