Buy to Open vs. Sell to Open

There are only two possible orders when trading options (calls or puts): open or close.


While most new options traders are acquainted with the concept of "buying to open" options calls and puts, they may be confused with the idea of "selling to open" options.

What Are Options

Essentially, each option is a contract between a buyer and a seller.


An options contract provides traders with the right, but not the responsibility, to buy or sell shares at a fixed price within a particular time.


Additionally, you may think of options as a wager between a buyer and a seller since both are betting on the future direction of the price.


For instance, you may believe that self-driving cars will be less expensive than conventional automobiles five years from now, but the vendor of such vehicles thinks not. You may engage in an options agreement that gives each of you the opportunity (and the right) to purchase or sell an autonomous car at a specified price on a particular date, regardless of the actual price.

How do Options work

One option entitles the holder to a defined percentage of the underlying securities. For instance, who may use one option to control 100 shares of stock? There are two kinds of options to trade: calls and puts. A call option allows you to buy the underlying securities, while a put option entitles you to sell. Unlike stocks, however, options are a waste of money. The value of an option declines as the expiry date approaches. Your risk is partially determined by whether you are buying or selling the option. When you purchase a call or put option, your risk is limited to the option's purchase price and broker fees.

How Is Options Trading Defined?

The term "options trading" refers to buying or selling options on the market.


Traders may either enter into a contract to generate a new option or exchange their current holdings for an existing option.


Thus, several buyers and sellers may exchange options over a predetermined time. The exchange will keep track of all transactions so that the contract's ultimate owners have a complete picture of when it expires.


It's critical to understand that this contract comes with a charge. It is a predetermined fee that acts as a deposit of sorts. The purchaser may use it as a down payment to secure their right to buy at a specific price on or before the specified date.

As an example, you might write an option contract stating that the price of Google stock would rise over $3,001 in the next two years and that you would want the option of purchasing it at $2,500 per share at any time during those two years. If you agree with another party (a seller who says that the share price will be lower) on a premium price of $10,000 for this contract, you must pay the premium for the agreement to be genuine.


Options are not identical to equities. While options are generated from the underlying stock, they do not reflect ownership.

Two Types of Options

Options are classified into two types: call options and put options.

Call

A call option is a form of option contract in which the buyer wagers that the underlying stock's price will increase while the seller wagers that the price will not exceed the strike price. If the stock price rises above the strike price, the buyer profits from the ability to buy the shares at the strike price, which is less than the current market price. However, if the stock price does not rise over the strike price, the buyer of the call option forfeits the option, and the seller retains the premium.


Now, let us consider the put option.

Put

A buyer of a put option is an investor speculating that the underlying stock's price will decline. Consequently, the buyer of the option expects to benefit by persuading the seller of the option contract to purchase the underlying stocks at a premium to the stock's market price. On the other hand, the seller of a put option is betting that the underlying stock's price will increase. If the underlying stock price increases, the buyer of the put option has no option to exercise, and the seller of the put option profits by retaining the premium received.


Consider a structure that is presently under construction to better understand this. Once finished, say in two years, the ultimate price of an apartment in this building will be determined by the real estate market in that location two years later.


Before we discuss the call and put options, it's necessary to define another term: striking price. A striking price is a predefined price for an underlying asset agreed upon by both the buyer and seller.


For instance, suppose the striking price for an apartment in a newly constructed building is $1,000 per square foot. Now, let's examine what occurs when call and put options are used in this scenario:


The buyer wagers that the market price of an apartment will reach $1,000 per square foot within two years, while the seller wagers that it will not. If the buyer proves to be correct, they may buy the flat at the strike price during those two years and afterward sell it for a profit at the valid market price.


The buyer of put options wagers that the market price of an apartment will go below $1,000 per square foot during the following two years, while the seller wagers that it will not. It's possible that the buyer, if they're right, will purchase the apartment for less and then sell it to the option seller for more. The seller is then obligated to acquire it at the strike price.


This takes us to four fundamental techniques to trade the options market:


  • Buying a call option 

  • Selling a call option 

  • Buying a put option 

  • Selling a put option 


In general, both the buyer and seller of options want to profit, but somewhat differently.


Important note: Options are less risky than stocks since they allow for unlimited withdrawals. They do, however, carry some risk due to their speculative character.

What is Sell to Open?

The term "sell to open" refers to establishing a short option position by the writing or selling of an options contract. When a trader sells to open, he or she is showing a temporary options position. Consider a sell to open as "opening an options contract via writing or selling."


Options writing is the process of "selling to open" a call or put. You get a premium when you sell to open since you are selling another market participant the option's rights. Effectively, you've shorted the call or put. You benefit if the underlying stock does not go over your strike price. Generally, you would sell volatility if you believed it was expensive.


To finally "buy to close '' such "sell to open" positions, you must eventually "sell to close" the call or put. Akin to shorting a stock, selling to open a put is similar to shorting a stock. To close a short stock position, you would buy the stock, and you would buy to close the sell-to-open option position. In contrast to shorting stocks, when you sell to open, you do not borrow pits. Simply put, you are constructing new derivatives on the original stock.


Selling to open a call poses an infinite risk. However, selling a call option on a stock you currently own is one approach to boost your portfolio's income. This technique is referred to as covered call writing. When you sell to open a call, you get a premium and limit your risk since you already hold the stock and will be able to deliver it if the call you sold is exercised.

How Does A Sell To Open Trade Operate?

A "sell to open" transaction occurs when an option trader (or investor) initiates an options trade by taking a short position on an option (or selling it).


The investor may collect the premium from the option buyer by selling options.


In a sell to open transaction, the seller of the option takes a short position in the underlying call or put option. In contrast, the option buyer takes a long position in the same underlying option contract.


The trader profits from a sell to open position by forecasting that the underlying asset's price will remain below the option strike price until the option expires.


The merchant retains the premium paid by the customer in this manner.


However, if the underlying stock price rises over the strike price, the long position of the option buyer wins.

What Is Buy to Open?

The word "open" refers to the fact that you are opening a position when you initiate a transaction. Thus, buy to open implies that you are buying an option to open a position.


When purchasing a new long call or long put, you must employ a buy-to-open order. This may imply to other market players that you've seen an opportunity in the market, particularly if you're placing a big order. However, if you place a tiny order, you are probably utilizing the buy-to-open order for spread or hedging purposes.


Let us put this into context. Consider purchasing a call option on an underlying stock selling at a $1.30 premium and has a two-month expiration date. Assume the trade price is $50, and the call has a strike price of $55. To buy this call option through your brokerage, you must place a buy-to-open order.


When the moment comes to sell, you must utilize a sell-to-close order. This may be done at any moment – even the day after the buy-to-open order is used. In the above example, you may choose to sell to close if the underlying stock price climbs to about $57 before the expiration date. When a sell-to-close order is used, the open option is closed.


Bear in mind that not all buy-to-open orders will execute. This may occur when an exchange restricts closing orders to certain market circumstances. A market circumstance that fits this description is when the underlying stock for the option you're attempting to buy to open is slated to be delisted. Another possibility is that the exchange will not trade the stock for an extended time.

Buy To Open vs. Sell To Open

Once you've selected the equities and options you want to trade, you'll be given a choice to "sell to open" or "buy to open."


When you are going long on an option, you want to pick buy to open. When you go long on a call or put option, you do not need any underlying stock or cash to support the position. You are buying the option to open the trade. This is the order input method that many individuals are used to and begin with when investing in or trading options for the first time.


When you sell to open a position, you effectively sell short or write an option. To sell an option and build a position, you must have either the underlying stock or its cash equivalent as collateral.


If you do not have the stock to back up yourself to open' an order, you are selling a 'naked position' or shorting the option. If you own the shares necessary to support the sell to open' transaction, you are selling a 'covered position.' This is the premise for our approach here: to write covered calls; when selling covered calls, we employ the sell to open order.


Ensure that you select your input order appropriately. With a single incorrect mouse click, you may lose a significant amount of money just by not understanding which order type to utilize.

Comparing Other Trades

Buy to Open vs. Buy to Close

If an investor wants to buy a call or a put in order to benefit from the underlying security's price movement, the investor must buy to open. Buying to open opens a long options position, which allows a speculator to earn a very high profit with very minimal risk. On the other hand, the security must move in the desired direction within a certain period, or else the option would expire worthless due to time decay.


Although sellers have a time decay advantage over buyers, they may wish to buy to close their holdings. When an investor sells options, the investor is still bound by their terms until the options expire. However, options on the underlying security's price might enable option sellers to cash in on most of their gains much sooner or push them to curtail losses.


Assume someone sells at-the-money puts with a one-year expiration date, and the underlying stock increases 10% after three months. The options seller may buy to close and get the majority of the earnings immediately. If the price falls 10% after three months, the options seller will have to pay a premium to close the position and buy possible losses.

Sell to Open vs. Sell to Close

A Sell to Open order is one in which you sell an upcoming options contract short. This may be accomplished by selling to open a call-bearish trade or by selling to open a put-bullish trade. Due to the fact that market players buy and sell options contracts in a marketplace, participants may either buy/sell an existing contract or make their own. They sell on a close order, though, and are used to sell an existing options contract that you already hold. They may be used for both calls and put options.


A Sell to Open order allows you to construct a new options contract (referred to as "writing" a contract) that other options traders will buy from you.


If the option holder decides to exercise their right, you are compelled to sell them the security at the strike price, regardless of the security's actual price. However, with sell to close, if the underlying stock price climbs, you may keep the call option until it expires and exercise your right to buy the agreed-upon number of underlying stocks at the agreed-upon strike price.

There are many ways to handle a sell to open order, depending on whether it is a call or a put. However, for the seller to close, the contract's value rises as the underlying stock's price climbs, and vice versa for put options.


When you write an option, you provide the buyer the right, but not the responsibility, to purchase the underlying security from you at an agreed-upon price (called the strike price).

Conclusion

A sell to open order is utilized by an options trader who intends to profit from a contract's value drop. Additionally, the sell-to-open order generates a new options contract that another trader purchases. You are constructing a short option position or contract when you sell to open.
