AAPL is being pinched in between the 200 day and 20 day moving averages. We have a supply overhead at the 169.25 / 168.50 and demand at the 165.40/164.10.
You can use those areas as levels on small intraday timeframes for potential day trades. The 163.24 is an area below marked in yellow where I expect AAPL to remain above by end-of-day Thursday, since markets are closed on Friday.
Watch the QQQ and NASDAQ-100 Futures for additional levels of confirmation and weakness.
