## Understanding the Fundamentals of Buy Stop Orders

A buy stop order often protects against unlimited [losses in a short position](https://www.investopedia.com/ask/answers/05/shortsalestoploss.asp). If an investor bets on a security's price drop, they can profit by buying cheaper shares and covering the [short](https://www.investopedia.com/terms/s/short.asp) sale. The investor can protect against a rise in share price buy placing a buy stop order to cover the short position at a price that limits losses. When used to resolve a short position, the buy stop is often referred to as a [stop loss order](https://www.investopedia.com/terms/s/stop-lossorder.asp).

A short seller can set a buy stop price lower or higher than their original short entry. If the price falls significantly, placing a buy stop below the initial price protects profits from price increases. An investor looking only to [protect against catastrophic short position loss](https://www.investopedia.com/ask/answers/05/buystoplimit.asp) from significant upward movement will open a buy stop order above the original short sale price.

## Leveraging Buy Stop Orders in Bullish Markets 

While buy stop strategies often protect against rising prices, they can also profit from expected price increases. [Technical analysts](https://www.investopedia.com/terms/t/technical-analyst.asp) look at [resistance and support](https://www.investopedia.com/trading/support-and-resistance-basics/) levels, where resistance is the price ceiling, and support is the price floor. Some investors, however, anticipate that a stock that does eventually climb above the line of resistance, in what is known as a [breakout](https://www.investopedia.com/terms/b/breakout.asp), will continue to climb. A buy stop order can be very useful to profit from this phenomenon. The investor will open a buy stop order just above the line of resistance to capture the profits available once a breakout has occurred. A stop loss order can protect against subsequent decline in share price.

## Real-World Scenarios: How Buy Stop Orders Work 

Consider the price movement of a stock ABC that is poised to break out of its trading range of between $9 and $10. Let’s a say a trader bets on a price increase beyond that range for ABC and places a buy stop order at $10.20. Once the stock hits that price, the order becomes a market order and the trading system purchases stock at the next available price.

The same type order can be used to cover short positions. In the above scenario, assume that the trader has a large short position on ABC, meaning that she is betting on a future decline in its price. To hedge against the risk of the stock’s movement in the opposite direction i.e., an increase of its price, the trader places a buy stop order that triggers a buy position if ABC’s price increase. Thus, even if the stock moves in the opposite direction, the trader stands to offset her losses.

## The Bottom Line

A buy stop order is a strategic tool used to purchase securities when they reach a specified price, offering investors opportunities to capitalize on upward price movements or protect against losses in short positions. Investors should consider employing buy stop orders to either safeguard against significant losses in an uncovered short position or to harness potential profits from a breakout above resistance levels. As always, understanding how these orders function within the broader market context is crucial for making informed decisions. Engage with this strategy to effectively manage risk and seize potential opportunities in changing market conditions.
