From a 1-hour basis, a peak formation was being formed at the start of the week and this was threatening to send the price into the 0.6850s for the day ahead on a break of 0.6880 structure.
The doji followed by the bearish engulfing was a compelling formation that exposed the 61.8% Fibo of the prior bullish impulse that meets the prior resistance structure.
The price has since corrected to test the prior highs again but has failed to do so with conviction considering the tepid pace followed by a shape move to the downside.
From a 15-minute perspective, the bears need to get below 0.6875 should 0.6890 hold as resistance.
