First indicator for a bullish trend was that the 8 and 13 EMAs are above the 50 EMA. It also stayed above the 38.2% fibonacci line. That was the second indication that suggests to me that it's still moving up.
Please note that I'm still learning how to use the fibonacci properly but their levels have been matching my support/resistance lines. Only know a bit about how to use the retracement and still learning how to draw extensions.
