比如要其他国家买飞机，或者美国海军的飞机合同要赢了？（2选一）
6×100=600
600块可以买100合同。
不行就再买点ratio put?
I have not done any 波段 trading on BA (unlike other high flying stocks I hold), because this is the accumulation phase, not distribution phase for BA
When BA reaches 300 some day, I will probably start to trade in and out some positions
