On the chart you see my perspective of the current daily situation. I believe we are building an ascending triangle which is a bullish pattern. Its likely 820 will be tested again and maybe even the area of 850 will be hit. We will then either break through and complete the daily head & shoulders pattern or we will go down and probably start forming an ascending triangle.
The 61.8% fib retracements proves reliable time and time again on any timeframe so this is a likely area for price to find its PRZ.(price reversal zone)
