What Is Buy To Open (BTO) In Options Trading?

"Buy to Open" refers to initiating a new long position in an options contract. When a trader believes that the price of an underlying asset will move in a certain direction, they may choose to "buy to open" a call or put option accordingly. This order signifies the creation of a new position instead of closing an existing one. 

Understanding the various order types in options trading is crucial for effective strategy execution. One fundamental order type is "Buy to Open" (BTO). This article delves into what BTO means in options trading, how it functions, and its strategic applications.

Understanding Buy To Open Orders

In options trading, the terminology extends beyond simple buying and selling. Traders must specify whether they are opening or closing a position. A "buy to open" order establishes a new long position in either a call or put option. This means the trader is purchasing the option contract expecting its value to increase.

Types Of BTO Positions

When traders decide to buy to open an options position, they must consider whether they expect the underlying asset's price to rise or fall. Depending on their market outlook, they can choose between a long call option or a long put option. Each approach serves a distinct purpose and aligns with different trading strategies.

Long Call Option (Bullish Outlook):

  • Scenario: A trader expects the price of an underlying asset to increase. 
  • Action: They execute a buy to open order for a call option, which grants them the ability to purchase the asset at a predetermined strike price before expiration. 
  • Objective: Generate profits from the asset's appreciation by exercising the option or selling it for a higher premium.

Long Put Option (Bearish Outlook):

  • Scenario: A trader anticipates a decline in the price of an underlying asset. 
  • Action: They initiate a buy to open order for a put option, allowing them to sell the asset at a specified strike price before expiration. 
  • Objective: Capitalize on the asset’s price drop by exercising the option or selling it at a higher premium.

Strategic Applications Of Buy To Open Orders

Traders utilize Buy To Open orders to capitalize on anticipated market movements:

  • Speculation: Traders may buy to open call options if they predict a significant upward movement in the underlying asset's price, aiming to profit from the appreciation of the option's value. Conversely, they might buy to open put options if they foresee a substantial asset price decline.
  • Hedging: Investors holding a particular asset might buy to open put options to protect against potential losses from a decline in the asset's value. This strategy serves as an insurance policy, mitigating downside risk.


Buy To Open Vs. Other Order Types

It's essential to distinguish buy to open from other related order types:

  • Sell to Open (STO): This order initiates a new short position in an options contract. Traders sell to open when they believe the option's value will decrease, allowing them to buy it back at a reduced price for a profit.
  • Buy to Close (BTC): This order is employed to close an existing short position. If a trader has previously sold an option (establishing a short position), they will buy to close to exit that position.
  • Sell to Close (STC): This order is used to close an existing long position. Sell to Close applies to closing a long position after the initial "Buy to Open" order.


Practical Example Of A Buy To Open Order

Consider a trader who believes that Company XYZ's stock, currently trading at $38, will rise to $48 in the next month. The trader places a Buy To Open order for a call option with a strike price of $42, expiring in one month, paying a premium of $2.50 per share.

If the stock price rises to $52 before expiration: The call option is now in-the-money. The trader can exercise the option to buy the stock at $42 and sell it at the current market price of $52, realizing a profit of $7.50 per share ($10 gain minus the $2.50 premium paid).

If the stock price remains below $42: The option expires worthless, and the trader loses the premium paid ($2.50 per share).

Risks And Considerations

While buy to open orders offer significant gains, they also come with risks:

  • Premium Loss: If the anticipated price movement does not occur, the trader will lose the entire premium paid for the option.
  • Time Decay: Options have expiration dates, and their value diminishes as this date approaches, especially if the option is out-of-the-money.
  • Market Volatility: Unexpected market movements can adversely affect the option's value, leading to potential losses.
