Question about Tentative news

Hi every one
Today we have a Tentative news on gbp . What does it mean ? It’s a very important news on Gbp , can we trade on this gbp crosses or not ?
I’ve stopped out , I’ve a buy position on the last day’s low , about 1.5585 and another but on the gbp/jpy about 121.02 and both of them stopped out .

What is the problem of this position ?

Thanks
