Once the channel breaks together with the daily 50 EMA, we can expect the price to go north and test the weekly 50 EMA which lies at 84.300 level. the blue line support is derived from the monthly charts and its a concrete support which has been rejected and the price shows it might climb up. For this to happen the channel must break.
This just represents my analysis of the pair, shall there be any updates in the future regarding trade entry i will post them in a new thread. cheers
