Patiently waiting for the long opportunity

Hi here! As we can see, EURUSD have been on an uptrend since 29 june 2017. The higher heights and higher lows are clearly visible and represented with my green lines. On the daily timeframe, the general trend is upward (the red line). As per the basics, we should be only looking for long opportunities. For the moment, I can't find any suitable long opportunity, so I will wait for the price to reach the red trandline level. There, I'll be looking for my long opportunity
