GU has been very bullish on the Hourly timeframe. We look like we could need a retracement. Price has approached an area of resistance as seen by the behaviour of the candlesticks. We recently saw a bullish candle attempt to close above this resistance and fail. Price is currently forming a bearish candle. This along with the previous candle could be seen as a spring.
When we have confirmed this spring, we could scale down to lower timeframes for sells till price gets to a key level.
