Apple Inc. (AAPL) has had a good run in 2017 and was still rallying in August. After almost tagging 165, AAPL started retreating and might fall a bit further in the coming weeks. However, because the prevailing trend is bullish and we should maintain a bullish bias and give some respect to previous support levels.AAPL Daily Chart (click to enlarge) Support/Resistance Pivot:- As AAPL falls below 160, I think the next level to monitor is around 155.- The 154-156 area involves some common support and common resistance pivots.- Price might not find support here, but might instead become "sticky" around here. In other words, we might see price become choppy around 155.- If price bounces off 155, it would be evidence that bulls are still in control.- A break below 154 suggests a longer period of consolidation, which downside towards 150. - I think 150 would be an ideal buy-on-the-dip price target for a strong reward to risk trade. But if AAPL is still bullish, we might not see price retreat to 150, and instead find support around 155.- The upside is at least back to the high on the year around 165 with a good chance of further upside if price does get back up to 165.The RSI:- Another thing to look out for is when the RSI approaches 40. If the market is still bullish, the RSI should hold and turn back up.- So, if price indeed pauses around 155 and the RSI coincidentally holds right around 40, expect a bullish attempt to follow.
