However, there are some pairs that already show a potential turning point in the making. GBPUSD and USDCAD looks quite interesting. However, break above 1.3450/64 is still needed on cable to confirm bullish price move, while USDCAD needs a broken channel line near 1.2350 to confirm a bearish continuation.
