What a market gap actually is
A market gap is an area where little or no trading takes place between two prices. Imagine a stock closes at 100 dollars on Friday. During the weekend, the company announces bad news. When trading starts again on Monday, buyers may no longer be willing to pay 100 dollars. The first trades could happen at 94 dollars instead. The six-dollar difference between Friday's close and Monday's opening price is the gap. The same thing can happen in the opposite direction after positive news. Gaps are especially visible in stocks because exchanges have clear opening and closing hours, but they can also appear in forex, indices, commodities, and other markets. Weekend gaps are common examples in forex because normal trading stops for the weekend and resumes when the new trading week begins. During the time when the market is closed, information can still change what traders are willing to pay. When trading starts again, the price adjusts immediately to that new information.
Why a ranging market needs a different approach
The biggest danger is that a gap can make your planned exit price impossible to execute. Imagine you buy a stock at 100 dollars and place a stop loss at 95 dollars because you are willing to lose about 5 dollars per share. If unexpected news arrives while the market is closed and the stock opens the next day at 90 dollars, there may be no opportunity to sell at 95 dollars. A normal stop order can be triggered when the market opens and then execute near the next available price, which could be around 90 dollars. Instead of losing 5 dollars per share, you may lose around 10 dollars. This difference is known as slippage. The same risk exists when holding leveraged positions, where a larger-than-expected price move can have a much bigger effect on the account. This is why holding trades overnight or over the weekend can carry additional risk. Your stop-loss is an instruction to exit, but it does not guarantee the market will always execute at the exact price you selected.
Why traders should not assume every gap will close
One of the most common ideas about gaps is that the market will eventually return to the previous closing price and fill the gap. This does happen, but it is not a rule. A gap can represent a real change in how the market values an asset. If a company reports much stronger earnings than expected, the stock may open significantly higher because traders now believe the business is worth more. There is no reason the price must immediately return to where it traded before the announcement. The same applies after serious negative news. Some gaps are filled within hours or days, while others can remain open for weeks, months, or even longer. This is why entering a trade only because a gap exists can be dangerous. The gap itself does not tell you where the price will move next. Traders still need to consider the reason behind the gap, the size of the move, current market conditions, and how much they are prepared to lose if the price continues moving in the same direction.
Conclusion
Market gaps show why trading risk does not disappear when the market closes. Prices can change because new information continues to arrive even when normal trading is not available. When the market opens again, that information can create a sudden jump to a completely different price. For beginners, the most important lesson is that stop losses and planned exit levels cannot always protect you at the exact price you expect. Gaps can create slippage and losses larger than your original calculation, especially when leverage is involved. It is also important to remember that a gap does not have to be filled. Understanding these risks before holding a position overnight or over the weekend can help you avoid one of the more surprising parts of trading.
