Edwards & Magee

Technical Analysis & Breakout Trading

Robert Edwards and John Magee wrote the book — literally. Their 1948 work defined how generations of traders think about support, resistance, chart patterns, and volume-confirmed breakouts. Every time you draw a trendline or look for a resistance break, you're using their framework.

The methodology at a glance

At its core, the Edwards and Magee approach is about identifying key price levels (support and resistance) and watching what happens when price reaches those levels. The trading signal comes from how price behaves at resistance — and crucially, whether volume confirms the move.

Kasauti's Magee Breakout Filter

  1. Price within 5% of the 52-week high — testing the most significant resistance level
  2. Volume ratio ≥ 1.5× average — above-average volume confirms institutional participation
  3. Positive day change — price is moving up, not just churning near resistance
  4. Price above the 50-day moving average — short-term trend supports the breakout

Who are Edwards and Magee

Robert D. Edwards and John Magee co-authored what is widely considered the foundational text of technical analysis. First published in 1948, it was the first rigorous attempt to catalogue and systematise chart patterns — head and shoulders, double tops and bottoms, triangles, flags, channels — and to explain how volume confirms or denies the validity of price movements.

Magee was the practitioner; Edwards was the theorist. Together they created a framework that has been continuously updated and remains in print nearly eight decades later. The underlying principle — that price action at key levels, confirmed by volume, reveals the balance of supply and demand — is timeless and universal.

Key principle: A breakout without volume is a lie. Edwards and Magee hammered this point: when price breaks above resistance, volume must expand. If it doesn't, the breakout is likely to fail. Volume is the fuel; without it, the move has no legs.

How Kasauti implements it

The Magee button applies a client-side filter that surfaces stocks showing the exact pattern Edwards and Magee described: price pushing against 52-week resistance with volume confirmation and a positive trend backdrop. These are real-time breakout candidates — the stocks where supply is being overwhelmed by demand right now.

Kasauti Insight · Nuances for Indian markets

Indian stock volume patterns have a specific quirk that makes Edwards & Magee's volume-confirmation rule especially important: foreign institutional investor (FII) flows create non-stationary volume baselines. In periods of heavy FII buying, average daily volume on NSE stocks can run 30–50% higher than during FII selling phases. This means a 'normal' volume day in one period might register as a 'high volume' breakout in another.

The practical fix: when applying Magee's methodology on NSE, use the volume ratio (today's volume divided by the trailing 50-day average) rather than absolute volume numbers. Kasauti computes this automatically — any stock showing a 1.5× ratio or higher has genuine institutional interest regardless of whether the broader market is in a high-volume or low-volume regime. This adjustment is critical for Indian markets in ways it might not be for more uniform foreign markets.

RESISTANCE (52W High) 1.5× Vol BREAKOUT The Magee Resistance Breakout Multiple tests of resistance · Volume spike confirms breakout · Trend intact For representation only
A Magee-style resistance breakout — price tests the 52-week high multiple times, then breaks through on 1.5× average volume.
Continuation Pattern

Ascending Triangle

For representation only

Price tests a flat resistance line repeatedly while making higher lows. Breakouts above the flat top are typically continuation moves in an existing uptrend.

Continuation Pattern

Symmetrical Triangle

For representation only

Lower highs meet higher lows, compressing into an apex. The breakout direction is unknown until it happens, but volume contraction during formation is the key tell.

Reversal Pattern

Broadening Top Formation

For representation only

Increasingly wild swings in both directions on rising volume. A bearish reversal signal at market tops — the megaphone shape reflects emotional extremes and distribution.

Reversal Pattern

Inverse Head & Shoulders

Neckline L Shldr Head R Shldr For representation only

Three troughs with the middle one deepest, all under a flat neckline. A bullish reversal pattern after a downtrend — the breakout above the neckline on volume confirms the trend change.

Frequently Asked Questions

Why is volume so important in Edwards & Magee's breakout methodology?

Volume reveals whether a breakout is supported by real buying interest or is just drift. When price breaks above a resistance level with 1.5× or higher average volume, it indicates that institutional participants are accepting the new price level — meaning the breakout has conviction behind it. A breakout on normal or below-average volume is far more likely to fail, because there isn't enough demand to sustain the move.

What's the difference between support, resistance, and a trendline?

Support is a horizontal price level where buying has historically overwhelmed selling. Resistance is the opposite — a level where selling has historically overwhelmed buying. A trendline is a sloped line connecting a series of rising lows (uptrend line) or falling highs (downtrend line) that acts as dynamic support or resistance. All three concepts are defined by Edwards and Magee and remain the foundation of technical analysis today.

How close to the 52-week high should a stock be for a Magee-style breakout?

Kasauti's filter requires the stock to be within 5% of its 52-week high, because meaningful breakouts typically occur at or very near major resistance levels. A stock that's 15% below its high isn't 'breaking out' — it's rallying within an existing range. The proximity to the 52-week high is what makes the breakout significant and institutionally meaningful.

Can I use Edwards & Magee patterns on Indian smallcap stocks?

Yes, but with caution on liquidity. Chart patterns work across all market segments, but smallcap stocks can have erratic price action due to low volume, making the pattern less reliable. Kasauti's filter includes a minimum volume threshold to avoid this. When applying Magee-style analysis to NSE smallcaps, the volume confirmation becomes even more important than usual.

Why doesn't Kasauti have a 'head and shoulders' or 'triangle' filter?

Edwards and Magee catalogued dozens of patterns, but most require subjective pattern-recognition judgement that doesn't translate well to a quantitative screener. Kasauti's Magee filter focuses on the one pattern that can be reliably quantified: resistance breakouts with volume confirmation. More complex pattern recognition (VCP, Cup & Handle, triangles) is planned for future releases as Pro Plus features.
