国内有朋友托我认识新加坡的交易员，只是单方面认识一下，想了解一些类似如下的信息：
I buy 20mio GBP call JPY put strike 130 rko 148 (unwinding)
I buy 20mio GBP put JPY call strike 160 ako 148 (unwinding)
I buy 30mio GBP call JPY put strike 130 rko 148.5
I buy 10mio GBP put JPY call strike 160 ako 149.50
I sell 10mio GBP put JPY call strike 160 ako 148
All the options expire on 12 Jul 2018
I sell 1mth 25mio GBP put JPY call strike 160 rko 135
I sell 1mth 25mio GBP call JPY put strike 130 rko 155
这是什么信息啊，难道不是公开的吗？怎样能了解到呢？
