AAPL Gapped Down: The New Map I’m UsingApple Inc.NASDAQ:AAPLtmac1914Posted after the open (10:00 AM ET). Educational, not a call. AAPL gapped down hard overnight on reports that Apple cut iPhone 18 Pro production orders because of memory chip costs. The rest of the market is green. When a stock moves this far this fast, yesterday's levels stop being useful, so I switch maps. WHY YESTERDAY'S PD-15 BOX IS OFF THE TABLE TODAY PD-15 (Previous Day 15-minute) is the high and low of yesterday's last 15 minutes. It works when today opens near it. Today AAPL is trading roughly $7 to $9 below it. Using it now is like using yesterday's weather report to decide what to wear today. The news already changed the weather. WHAT I USE INSTEAD - Premarket high (PMH): the highest price before the market opened. Today that's $340.61. - Premarket low (PML): the lowest price before the market opened. Today that's $330.74. Those two lines show where AAPL actually traded after the news hit. That's today's real range. WHY I ADD THE FIB LINES After a big drop, a bounce usually gives back part of the drop before the stock decides what's next. Fib (short for Fibonacci) lines measure how much of the drop has been given back: 50% (about $336.75), 61.8% (about $337.67), and 78.6% (about $338.97). A lot of traders watch these same lines, so price often pauses there. They're not magic. They're crowded spots, and crowds move price. HOW I'M READING IT (education, not signals) - Falls back through the PML and can't climb back above it: sellers still have control. I'd want a 2-minute candle (one small bar that covers 2 minutes of trading) to close below the line with strong volume (a busy crowd behind the move), then a pullback that fails at the line. - Bounces but stalls at the 50% or 61.8% line: the bounce is weak. Buyers couldn't get through. - Closes above the 78.6% line and holds: buyers are gaining ground. Fully reclaiming the PMH is what would change the story. - Chops in the middle on weak volume: I skip it. Sitting out is a decision too. The bigger lesson: when the news changes the map, change the map. And a bounce isn't a plan until it holds. Study the levels. Wait for agreement. Trade with discipline. Educational purposes only. Not financial advice. Options trading involves substantial risk.
