Gapping into Trading Success

Gaps are a normal part of trading. Traders can view these gaps as a great inconvenience or an excellent opportunity. The key is to see what the price action is telling you after it gaps. Stocks gap due to a massive imbalance between buying and selling pressure. In an effort to balance out these orders, the price will gap to an area where the market’s supply and demand equation is right for filling the orders of the traders and investors. The gap left behind is a vacuum where there is an absence of buyers (a gap down), or an absence of sellers (a gap up).

Gaps are a magnet for price. They are usually formed when prices are impulsing in the trend direction. During corrections, price will often try to fill the gap. A gap fill means that prices have returned to the closing price of the candle before the gap itself. Once a gap has been filled, it has no more impact on price.

An interesting thing to see is whether prices were able to gap beyond the prior day’s price action. When I speak of the prior day’s price action, I am referring to the movement of price between the prior day’s high and the prior day’s low. If prices gap, but do not open above the prior high or below the prior low, then the gap is called an inside gap and is likely to fill during that day.


As an intraday trader, I like to identify stocks that are exhibiting this pattern and plan trades to take advantage of the gap filling as long as the broad market is also confirming the movement. The best trading opportunity occurs when prices gap inside of the prior day’s price action but opens into a supply or demand zone.

An inside gap could also have implications for swing traders as a gap that occurs opposite to their position may be able to be ignored, thus preventing panic and an early exit.

Should price gap above the prior day’s high or below the prior day’s low, then the gap is considered to be an outside gap. Outside gaps also offer interesting trading opportunities. They tend not to fill in the day, but instead will change direction at the prior high or prior low. If a stock does gap above the prior day’s high, it is an outside gap and will likely only fill until it reaches the prior high, which will act as support. If the markets are bullish, then expect a bounce here for a long.

If the stock gaps down and tries to fill the gap, often the prior low will act as resistance and cause the stock to drop from that point, thus identifying a shorting opportunity.

There are always exceptions to these guidelines on gaps, and traders should exercise caution and discretion when identifying trading opportunities surrounding gaps. Look at the broad market and also larger trends for guidance and, above all, place protective stops to manage your trades. Trade safe and trade well!
