Here as you can see I have found a potential SELL on EUR/USD seen on screen above.
Reasons for this are that that on the Fibonacci retracement tool, the price has fell below the 61.8 and is no retesting the 78.6, due to this I believe a sell is very possible.
However, if the price successfully retests, we could see a reversal to the 61.8 which would be a BUY signal.
