Measured Move (AB=CD)

The measured move, also called the AB=CD pattern, is a three-swing continuation structure that gives traders a mathematically derived price target before the second impulse leg has even begun. It appears in all trending markets — equities, futures, and forex — across every timeframe from 5-minute intraday charts to weekly swing charts. Unlike patterns defined purely by shape, the measured move is built on price symmetry: the second impulse leg (C→D) is expected to travel the same distance as the first (A→B), giving traders a concrete, pre-calculated exit level.

How to Identify the Measured Move

1. Strong impulse leg A→B — Look for a directional move covering at least 5 bars with expanding volume and minimal overlap between candles. This establishes the “measured” distance the pattern will project.

2. Corrective pullback B→C on declining volume — After the AB move peaks at B, price pulls back. The BC retracement must stay within 38.2%–61.8% of AB. This range, the golden zone documented in Edwards and Magee’s Technical Analysis of Stock Trends, confirms the trend is intact. A BC retracement deeper than 61.8% signals a potential reversal, not a continuation.

3. Structure holds at C — The C pivot must hold above key structural support (bullish) or below key resistance (bearish). Volume during BC should be noticeably lower than during AB, confirming the correction is consolidation rather than distribution.

4. Project the D target — Measure the price distance from A to B in dollars or points. Add that exact amount to the C pivot. This is the D target. It will also align with the 1.0 Fibonacci extension of AB plotted from C, creating a high-confluence zone.

5. Time symmetry check — Count the bars from A to B. If C→D completes in roughly the same number of bars, trend momentum is healthy. A CD leg taking 2–3x as long as AB is a flag for weakening participation.

Entry Rules

1. Wait for the CD breakout — Enter long when price breaks above the B high with volume at least 1.5x the 20-bar average. This confirms the CD leg is underway and prevents entering during an extended BC correction that may continue lower.

2. Verify the BC retracement depth — Before entering, confirm the BC correction stopped in the 38.2%–61.8% zone. Accepting a 70% or 80% retracement as “close enough” significantly lowers the pattern’s reliability.

3. Optional pullback entry — After the initial break above B, price sometimes retests the B level. Entering on that retest tightens the stop by $0.50–$1.00 per share, improving the risk/reward ratio without sacrificing the setup.

Exit Rules and Targets

1. Primary target at D (1.0 extension) — The D point is where CD equals AB in price distance. Most measured moves reach this level; continuation patterns across major equity and futures markets hit the 1.0 extension at rates broadly estimated at 55–65%.

2. Secondary target at 1.272 extension — When price reaches D with strong volume and no reversal candlestick, the 1.272 Fibonacci extension of AB from C serves as the next logical target. The 1.618 extension becomes valid when momentum is exceptional.

3. Partial exit and trail — Take 50% off at the primary D target. Trail the remaining position with a 10-bar ATR stop to capture any extension moves without giving back all the gains if momentum stalls.

4. Time-based exit — If price has not reached D within 2x the number of bars it took to complete AB, reduce or close the position. Prolonged CD legs lose the symmetry that defines the pattern and indicate that momentum has faded.

Target Calculation: Measure the price distance from A to B in dollars. Add that exact distance to the C pivot price to get the D target. Example: if AB spans $12 on SPY (from $420 to $432) and BC pulls back to $426, then D = $426 + $12 = $438. This D level also aligns with the 1.0 Fibonacci extension of AB plotted from C.

Stop Loss Placement

Place the stop 0.10–0.25 below the C swing low on bullish setups (or above the C swing high for bearish). A close beyond C means the corrective structure has broken down — the pattern is invalidated and there is no longer a measured basis for projecting a D target. This stop placement typically produces a 2:1 to 6:1 risk/reward ratio depending on the depth of BC and the size of AB. Never widen the stop to “give the trade more room” once C is broken; the structural premise of the pattern no longer exists.

Practical Example

On the daily chart of AAPL, a measured move sets up during an established uptrend. Leg A→B: price rallies from $170.00 to $185.00 — a $15 move over 9 trading days on steadily expanding volume. Leg B→C: price pulls back to $176.50 over 6 trading days on declining volume. The BC retracement is 56.7% of AB ($8.50 / $15.00), squarely within the 38.2%–61.8% golden zone. Measured move target: $176.50 + $15.00 = $191.50. The 1.0 Fibonacci extension of AB measured from C also plots at $191.50, confirming the level.

A trader with a $30,000 account risking 1% ($300) per trade places a stop at $174.00 — $2.50 below C. At $2.50 risk per share, the position allows 120 shares. Entry triggers when price closes above $185.00 (the B high) on volume above the 20-day average. If AAPL reaches $191.50, the reward is $15.00 per share × 120 shares = $1,800 — a 6:1 risk/reward ratio. Time projection: since AB took 9 days, watch for CD to complete near day 9 from C. If AAPL is still below $191.50 after 18 days from the C pivot, reduce the position.

Best Timeframes for the Measured Move

The measured move is timeframe-agnostic — the same AB=CD logic applies equally on 5-minute ES futures charts, daily stock charts, and weekly forex pairs. On the 5-minute chart, a complete pattern can set up and resolve within a single session, making it useful for intraday traders on index futures and high-liquidity ETFs. On the daily chart, the setup typically spans 2–6 weeks from A to D, which suits swing traders. Weekly charts produce the most reliable signals — the larger the timeframe, the more institutional participation backs the symmetry — but setups are less frequent. Intraday patterns below the 5-minute chart tend to generate too much noise for reliable AB=CD projection.

Common Mistakes

1. Entering during BC — Entering before the B high is broken means accepting a position where the pattern may not complete. Many BC corrections extend further than expected. Wait for the CD breakout confirmation.

2. Accepting deep BC retracements — A BC correction beyond 61.8% of AB is not an “almost measured move.” It signals the trend structure may be breaking down, and the CD leg will often fall short of D or reverse early.

3. Confusing measured move with harmonic ABCD — The harmonic ABCD (Scott Carney, Harmonic Trading) requires BC = exactly 0.618 or 0.786 of AB, and CD = 1.272 or 1.618 of BC. The classical measured move only requires CD ≈ AB in price distance. Applying harmonic Fibonacci rules to a classical setup produces incorrect targets and missed entries.

4. Ignoring time symmetry — A CD leg that takes 3–4x as long as AB signals diminishing momentum. These slow CD legs often stall before reaching D or reverse at the first sign of resistance. Time equality is not a requirement, but a significant divergence is a risk flag worth noting before adding size.

5. Failing to scale out at the primary target — Taking no profit at D and holding for the 1.272 extension without a plan is speculation, not pattern trading. The measured move gives you a defined target — use it.

How to Journal Measured Move Trades
