EUR 147,000 228,000 265,000 222,400

The market is very volatile due to the upcoming Brexit news.
Trendline does show a retracement to the 61.8% soon, hopefully after i reach my TP1, possibly TP2 as well.
Using minimal risk, very small lots.
*IF/Once TP hits, I am placing a long to reach that 61.8% level @ 0.87900 which I'm almost positive is where it's heading.
