In this case, price took a breather and rested at the 61.8% Fibonacci retracement level before resuming the uptrend. After a while, it pulled back again and settled at the 50% retracement level before heading higher.
Another way to see if price is staging a reversal is to use pivot points.
In an uptrend, traders will look at the lower support points (S1, S2, S3) and wait for it to break. In a downtrend, forex traders will look at the higher resistance points (R1, R2, R3) and wait for it to break.
If broken, a reversal could be in the making! For more information or another refresher, check out the Pivot Points Lesson!
