Gap trading

Runaway Gap Continuation

Add to a strong trend when it gaps again mid-move — a runaway or measuring gap that signals the trend's strength and often marks the halfway point of the whole run.

Rules at a glance

The mechanical checklist — decide these before you trade.

Entry
  • Confirm an established trend — price riding above a rising EMA (mirror for shorts).
  • Trade the fresh gap that appears mid-trend on strong volume: a runaway gap.
  • Buy the gap-up strength or the first shallow pullback toward the EMA that holds.
Exit
  • Project the measured move — the run into the gap, added on from the gap — as a target.
  • Trail beneath the rising EMA; a close through it ends the continuation.
Stop
  • Below the gap or the EMA; a fill of a runaway gap warns the trend is stalling.
  • Set the stop from ATR so normal trend volatility does not shake you out.
Filters
  • Require the gap to be with the trend, not against it — no counter-trend gaps.
  • Skip if the trend is already extended and climactic — that is exhaustion-gap risk.

The idea

A runaway gap — also called a measuring or continuation gap — appears in the middle of an already-established trend, when a strong move accelerates and jumps again in its own direction. It is a sign of conviction, not exhaustion: the trend is so one-sided that price cannot even trade at the intermediate levels. Traders call it a measuring gap because it often prints near the midpoint of the entire move, so the distance already travelled roughly projects the distance still to come. This is a pure continuation play — you add to strength in the direction of the trend rather than fading it — and it belongs squarely to the gap-and-go family. Anchored to a rising EMA that defines the trend and sized with ATR for the expanded volatility, the runaway gap is one of the highest-quality places to join a trend already in motion.

The setup

First establish that a real trend exists: price riding above a rising exponential moving average, making higher-highs and higher-lows, is the prerequisite, and the mirror holds for shorts under a falling EMA. Within that trend you are waiting for a fresh gap in the trend's direction, ideally on a burst of volume, that jumps price to a new level without filling. Mark the point where the strong leg into the gap began, because the measured-move projection is built from it. Use ATR to read the trend's normal volatility so you can tell a healthy runaway gap from an over-extended, climactic one. The ideal runaway gap is orderly and mid-trend, not the third gap of a vertical, parabolic run.

Entry

Buy the runaway gap's strength as it opens in the trend's direction, or, for a better price and a tighter stop, wait for the first shallow pullback toward the rising EMA and buy as it holds and turns back up. The trend structure means the pullback should be brief and contained; a deep pullback that slices the EMA is a warning the trend is weakening. Add only in the direction of the established trend — a gap against the trend is not a runaway gap and must not be treated as one. Confirmation that price stays above the EMA and the gap does not fill tells you the continuation is intact. Shorts mirror everything beneath a falling EMA.

Common price-action setups

How the signal typically plays out on the chart.

Ride the runaway gap

In an uptrend above a rising EMA, a fresh gap up on volume continues the move; add to the trend as it runs.

Add to trend
Trend extends
Pullback to the EMA

After the gap, price dips to the rising EMA, holds and turns up — a lower-risk continuation entry.

Buy the dip
Continuation higher
Runaway gap down

In a downtrend under a falling EMA, a fresh gap down on volume extends the decline; add short into the trend.

Exit and targets

The signature target is the measured move: take the size of the run from the start of the leg into the gap, and project that same distance from the gap, since a measuring gap tends to sit near the midpoint. Bank partial profit at that projection and trail the remainder beneath the rising EMA, letting a powerful trend extend past the measured target when it wants to. The key exit warning is a runaway gap that fills — because these gaps are not supposed to fill during a healthy trend, a fill signals the trend is stalling and the continuation is over. A close back through the EMA is the mechanical trail exit. This is a multi-day swing hold, managed on the daily chart.

Risk management

Place the stop below the gap or the EMA, since a fill of a runaway gap or a decisive EMA break both say the trend thesis has failed. Because trends carry expanded volatility, set that stop from ATR rather than a fixed tick amount, so ordinary trend noise does not eject you prematurely while still capping the loss. Size the position so the ATR-based stop equals a small fixed fraction of the account. The subtle risk is mistaking an exhaustion gap for a runaway gap late in an extended move; if the trend is already climactic and stretched far from the EMA, stand aside rather than add. Never add against the trend, and never widen the stop when a runaway gap starts to fill.

Best timeframes and markets

Runaway gaps are a swing setup on the hourly-to-daily chart, best on strongly trending stocks and ETFs where clean, persistent trends develop. Momentum leaders, sector ETFs in a strong move, and names in a post-breakaway trend are the natural hunting ground. The strategy is useless in rangebound, choppy markets, because there is no trend for a gap to continue. Trend-friendly market regimes produce the most reliable measured moves. Because it is a continuation-of-strength play, it pairs naturally after a breakaway gap: the breakaway starts the trend, and the runaway extends it.

Common variations

The most useful variation is stacking: a trend can print more than one runaway gap, and each mid-trend gap that holds is another continuation entry, though the risk of the next one being an exhaustion gap rises as the move matures. Some traders use the measured-move midpoint strictly as a profit target and exit fully there; others treat it only as a signpost and trail the whole position with the EMA. A more conservative version requires the pullback-to-EMA entry and never chases the gap open. On lower timeframes the same pattern appears intraday as a mid-trend gap on strong days. All variations keep the two anchors: an EMA-defined trend, and a with-trend gap that does not fill.

A worked example

A stock has trended from 40 to 52 over several weeks, riding above a rising 20-day EMA. Mid-trend it gaps up from 52 to 55 on strong volume and keeps going — a textbook runaway gap. The leg into the gap ran from roughly 40 to 52, so the measured-move projection from the gap points to about 55 + 12 = 67. You buy the first shallow pullback to 54 that holds above the EMA, with an ATR-based stop at 51.50 below the gap, risking 2.50 per share. The trend carries price into the 66-67 zone over the following weeks; you bank half near the measured target and trail the rest under the EMA, exiting around 64 when price finally closes below it. The runaway gap never filled while the trend was healthy.

Common mistakes

  • Treating a counter-trend gap as a runaway continuation gap.
  • Adding to a late, climactic run that is really an exhaustion gap.
  • Using a fixed stop instead of an ATR-based one and getting shaken out by trend noise.
  • Holding after a runaway gap fills, ignoring the sign the trend has stalled.
  • Chasing the gap open with a stop far too wide beneath the EMA.
