short on USDJPY

So usdjpy has been moving in a nice channel , it is now very close to a major trendline on the bigger timeframes.
As it was moving towards this trendline in an uptrend ,it broke its uptrending trendline ( on the shorter timeframes ) and is now moving downwards , there are a lot of buyers and sellers in this market right now trading against each other , but i believe this pair is overall moving downwards. As it is close to its trendline this might be a good sell oppurtunity
