She’ll needs to complete retracement before buying

Shell has been in an uptrend for almost 2 years now, but in my opinion is due a correction.
On the monthly chart we printed a bearish engulfing candle (not shown here), so a temporary top is probably in.
So looking for bullish signs once we reach the 0.382 or 0.618fib levels, at EUR 21.30 and 16.80 respectively.
