New contract event
This thing is no different from playing dice
And the disadvantage is that there is a limit. This is the biggest disadvantage. Theoretically, as long as you judge the short-term trend
you can make a greater profit and your profit and loss ratio should be 7/3
But as I said, the disadvantage is that it limits your transaction amount. If you start with a $2 bet
you can bet 2-5-10-20-50-100-250
in this way, but if you exceed 4 lots, your cost will be very high. If you can't make a profit, then your loss will be added to the above value 437u
So it's best to judge the short-term trend before opening #合约
