Technical Analysis & Chart Reading
Support, resistance, moving averages, and the volume clue most chart-watchers ignore.
Support and Resistance
Support is a price level where buying pressure has historically stepped in and stopped a decline. Resistance is the opposite — a level where selling pressure has historically capped a rally.
These levels matter because traders remember them: many people place buy orders near known support and sell/short orders near known resistance, which becomes a bit of a self-fulfilling pattern.
Moving Averages
A moving average smooths out day-to-day noise by averaging price over a window (e.g., the last 50 or 200 days). When a shorter-term average crosses above a longer-term one, it's called a "golden cross" and is read as bullish; the reverse is a "death cross," read as bearish.
Rare but important
Many retail traders buy the moment a stock closes above a well-known resistance level. But price alone doesn't tell you whether real buying conviction is behind the move — volume does. A genuine breakout, backed by institutions actually deploying capital, typically shows volume well above average (often 150%+ of the recent norm). A breakout on below-average volume is frequently a "fakeout" or "bull trap": the stock pokes above resistance on thin trading, lures in breakout buyers, then reverses back below the level once real supply reappears, trapping the late buyers at the top.
Worked Example
Problem: A stock has traded below $100 resistance for weeks. Today it closes at $101.50 on volume that is 40% below its 20-day average volume. The next day it closes back at $98. What happened, and what would have warned you in advance?
- This is a textbook fakeout: price cleared resistance, but without the volume to back it up, meaning there wasn't enough real buying demand to hold the breakout.
- The warning sign was visible before the reversal: comparing the breakout day's volume (60% of average) against what a "confirmed" breakout usually looks like (150%+ of average) would have flagged this as low-conviction.
- A disciplined trader either waits for a volume-confirmed close above resistance, or treats an unconfirmed breakout as a smaller, tighter-stop trade rather than a full-conviction entry.
