The outside strikes are commonly referred to as the wings of the butterfly, and the inside strike as the body. Closely related to the butterfly is the condor—the difference is that the middle options are not at the same strike price. While the basic calculation of the bid-ask spread involves pretty simple math, more complex calculations may be necessary. During dynamic, volatile markets, there may be more specific things that happen where it’s not so straightforward.
Imagine that you want to buy technology stocks, but you also want to limit losses. By using put options, you could limit your downside risk and cost-effectively enjoy all the upside. For short sellers, call options can be used to limit losses if the underlying price moves against their trade—especially during a short squeeze. Markets with a wide bid-ask spread are typically less liquid than markets with a narrow spread.
The bid is the price a buyer is willing to pay for a security, and the ask is the price a seller is willing to sell a security. A bid-ask spread is the difference between the highest price a buyer will pay for a security and the lowest price a seller will sell.

What Is the Difference Between a Bid Price and an Ask Price?
A long put is similar to a long call except that the trader will buy puts, betting that the underlying stock’s price will decrease. Suppose a trader purchases a one 10-strike put option (representing the right to sell 100 shares at $10) for a stock trading at $20. In a short call, the trader is on the opposite side of the trade (i.e., they sell a call option as opposed to buying one), betting that the price of a stock will decrease in a certain time frame. Because it is a naked call, a short call can have unlimited gains because if the price goes the trader’s way, then they could rake in money from call buyers.

When there is a significant amount of liquidity in a given market for a security, the spread will be tighter. Stocks that are traded heavily, such as Google, Apple, and Microsoft will have a smaller bid-ask spread. You can also convert a bid-ask spread to a percentage spread if you’re less interested in the actual dollar amount but you want more of a comparative metric. For instance, if the bid-ask spread is $1 and a stock is trading at $50, you may care more about a percentage spread of 2% ($1 / $50) as opposed to the nominal amount of $1. To be successful, traders must be willing to take a stand and walk away in the bid-ask process through limit orders.
The spread widens because there aren’t high levels of supply and demand, or buy and sell orders to easily match up. The higher transaction cost, in the form of a higher spread, is compensation to the market maker for the illiquidity. The strike price is the price at which you can buy (with a call) or sell (with a put). Call options with higher strike prices are almost always less expensive than lower striked calls. The reverse is true for put options—lower strike prices also translate into lower option prices. With options, the market price must cross over the strike price to be executable.
Despite the prospect of unlimited losses, a short put can be a useful strategy if the trader is reasonably difference between a database and a data warehouse certain that the price will increase. The trader can buy back the option when its price is close to being in the money and generates income through the premium collected. There are no upper bounds on the stock’s price, and it can go all the way up to $100,000 or even further. A $1 increase in the stock’s price doubles the trader’s profits because each option is worth $2. This spread would close if a potential buyer offered to purchase the stock at a higher price or if a potential seller offered to sell the stock at a lower price. On the other hand, less liquid assets, such as small-cap stocks, may have spreads that are equivalent to 1% to 2% of the asset’s lowest ask price.
The option’s premium fluctuates constantly as the price of the underlying stock changes. These fluctuations are called volatility and impact the likelihood of an option being profitable. If a stock has little volatility, and the strike price is far from the stock’s current price in the market, the option has a low probability of being profitable at expiry. If there’s little chance the option will be profitable, the premium or cost of the option is low. The bid/ask spread can vary greatly depending on the supply and demand for a particular product. Pay attention to the liquidity, because illiquid options with a wide bid/ask spread can cut into your potential profits, among other issues.
