EURUSD Trendline Break, Go Long

Price has broken structure and has given us a bullish engulfing candle on the 1 HR TF. Had an extremely steep retrace but price has found support at a trend-line which is also that 78.6 retracement area. Multiple TF analysis here with an entry from the 15m TF gives a tight SL but a huge gain. R:R is 17.5.
