Gap and Go
Definition
A momentum strategy where a trader enters a stock that gapped up (or down) at the open and continues moving in the direction of the gap — rather than filling it. The trader bets that the catalyst driving the gap is strong enough to sustain buying (or selling) through the open and beyond.
Example
“"Earnings were a blowout, the stock gapped up 15%, and pre-market volume was already 5x normal — classic gap and go setup, I was in the first 5-minute candle and out before lunch."”
Detailed Explanation
Gap and go is one of the most popular intraday strategies among active day traders. The setup begins before the market opens: you identify stocks that have gapped significantly from the prior day's close due to a catalyst — an earnings beat, FDA approval, major news, or a short squeeze in progress. The question is not whether the stock moved, but whether the catalyst is strong enough to attract continued buyers after the open, rather than profit-takers who will sell into the gap.
The critical filter is pre-market volume. A stock that gapped on a meaningful catalyst with heavy pre-market volume (3-5x or more above its normal average) is more likely to continue than one that gapped on light, thin pre-market activity. Heavy volume signals institutional and retail participation that tends to persist into the session. Low pre-market volume on a gap often means the move was driven by a small number of orders and will fade quickly at the open.
Entry timing is key. The most common approach is to wait for the first 1-minute or 5-minute candle after the open to close, then enter on a break above that candle's high. This avoids the chaotic opening seconds where spreads are wide and price discovery is erratic. A stop loss below the opening candle's low or the pre-market support keeps risk defined. The first target is often the next round number or pre-market resistance; many traders take partial profits there and trail a stop on the remainder.
Gap and go fails when the gap is already overextended relative to the catalyst, when the broader market opens weak, or when sellers show up immediately to fade the open. A stock that cannot break the opening candle's high within the first few minutes is often a gap fade candidate, not a gap and go. Knowing the difference — reading volume and price action in real time — is what separates profitable gap traders from those who chase every morning gap into a reversal.
