It’s time for the (YCS)?

Last year I've made a trade in the YCS betting that the 80 in the USD/JPY will hold. I lose some money in it. Not too much indeed.

Since then we have seen a lot of month a channel between 76 and 78,5. When would be the time for the yen to lose part of his strength? The BOJ used to do some periodic intervention in the forex market in order to make the yen cheaper and help the Japanese exporters.

I can talk a lot about the reasons for a movement of for another but it's not my intention here.

Graphically if it cans go throw the 78,3 level it can arrive to the 80 in very few sessions. I can make some money on it with the ETF (YCS) which is a double-short. I plan to buy it at 42,5 more or less with an objective of 44,5 at less. The stop as usual has to be very tight.
