The ask size is a crucial metric in trading, especially on platforms like thinkorswim. It represents the total number of shares or contracts that sellers are willing to sell at a specific price.
In thinkorswim, the ask size is displayed as a number, and it can range from a few shares to thousands. This number can fluctuate rapidly as market conditions change.
Understanding the ask size is essential for traders, as it helps them gauge market liquidity and make informed decisions. By analyzing the ask size, traders can determine if a stock is trading thinly or if there's significant buying or selling interest.
A higher ask size indicates more sellers are participating in the market, while a lower ask size suggests fewer sellers are present. This information can be used to adjust trading strategies accordingly.
Understanding Ask Size
The ask size is the number of shares a seller is willing to offer at the ask price.

This figure can be expressed in lots, which are usually 100 shares each or 10 shares each for large stock prices.
A larger ask size indicates stronger selling interest, which can drive the stock price downward.
Conversely, a small ask size means fewer sellers are willing to offer shares at that price, potentially pushing the stock price higher.
The ask size is typically shown next to the ask price and is a critical element of a stock quote.
Here's a breakdown of what the ask size can tell you:
- A larger ask size indicates more sellers are willing to sell at the current price.
- A smaller ask size means fewer sellers are willing to sell at the current price.
In the stock market, bid and ask sizes are often expressed in terms of 100 shares of stock, so a bid size of "1" really means 100 shares.
The ask size can be a valuable tool for traders, helping them anticipate potential price movements and make informed decisions.
By monitoring the ask size, traders can gauge the level of selling interest and adjust their strategies accordingly.
Ask Size in Trading

Ask size is a crucial metric in trading that can help you make informed decisions. It's the number of shares investors are willing to sell at a given price. Traders can use ask size to time their exits or short-selling strategies. If they notice large sell orders in the ask column, they may take this as a cue to sell before the price drops further.
Ask size is often expressed in "lots", which are usually 100 shares each or 10 shares each for large stock prices. This means that a bid size of "1" really means 100 shares. In the stock market, bid size and ask size represent 100 shares of stock.
Traders can use ask size to determine how many of their shares could be sold at a particular price. For example, if the number of asks is substantially greater than the number of bids, this suggests more investors are attempting to sell shares, which may potentially drive the security's price down.

The ask size can also be used to gauge the liquidity of a stock. If the ask size is large, it may indicate that there are many investors willing to sell shares at a given price, which can lead to a decrease in price. On the other hand, a small ask size may indicate a lack of liquidity, making it harder to sell shares quickly.
Here's a summary of what ask size can tell you:
- Large ask size: Many investors are willing to sell shares, potentially driving the price down.
- Small ask size: Lack of liquidity, making it harder to sell shares quickly.
- Large ask size compared to bid size: More investors are attempting to sell shares than buy shares, potentially driving the price down.
By paying attention to ask size, you can make more informed decisions about when to buy or sell a stock, and potentially avoid losing money due to poor timing.
Options Trading and Ask Size
Options trading involves understanding the ask size, which is the number of shares investors are trying to sell at a given price. This is crucial in determining future movements in stock prices.
A larger ask size compared to the bid size suggests more investors are attempting to sell shares, which may drive the security's price down. For instance, if the number of asks is substantially greater than the number of bids, it may indicate a potential price drop.
Market makers hedge options by buying and selling stock, and high stock volume means they can hedge easier, giving you better fill prices. Ideally, you want to trade options with high volume and open interest, as well as tight option spreads.
Here are some key points to remember about ask size in options trading:
- The ask size is the number of shares investors are trying to sell at a given price.
- A larger ask size compared to the bid size suggests more investors are attempting to sell shares.
- Tight option spreads result in less slippage for you.
- High stock volume makes it easier for market makers to hedge options.
Options Trading Liquidity Measures
Options trading liquidity measures are crucial for traders to understand, as they can greatly impact the success of a trade. Ideally, you want to trade options with high volume and open interest.
High volume and open interest indicate a liquid market, making it easier for market makers to hedge their options with stock. This, in turn, gives you better fill prices.
Option volume is the number of contracts traded on a given day, while open interest is the number of contracts currently in existence for a particular option. Both are important measures of option liquidity.

Option bid-ask spread is the difference between the bid price and the asking price. A tight spread means less slippage for you, but a wide spread can result in significant losses.
Here are some key liquidity measures to consider:
High stock volume generally means the stock is liquid, making it easier for market makers to hedge their options. This, in turn, gives you better fill prices.
Limit Orders
Limit orders are a type of order that specifies the maximum price you're willing to pay when buying, or the minimum price you're willing to accept when selling.
Unlike market orders, limit orders are not guaranteed to be filled immediately, and the bid-ask size plays a crucial role in determining whether and when your order will be filled.
If you place a limit order to buy shares at a specific price, but the ask size at that price is too small, only part of your order will be carried out.

The remaining shares will stay unfilled unless more sellers are willing to meet your price, illustrating the importance of bid-ask size in limit order execution.
For example, if you place a limit order to buy 2,000 shares at $50 but the ask size at that price is only 1,000 shares, only part of your order will be carried out.
Market Orders and Ask Size
Market orders are a type of order that can be partially filled if the ask size is smaller than the number of shares you want to buy.
If you place a market order to buy 1,500 shares and the ask size is only 1,000 shares, 1,000 shares will be bought at the current ask price, with the remaining 500 shares filled at the next available ask price.
The ask size is crucial in determining the price you'll receive when a stop order is triggered. If a stop-loss order is triggered, but the bid size is small, the order could be filled at a much lower price than expected.

Large institutional buyers or sellers can place orders that significantly impact bid and ask sizes, influencing the stock's short-term price direction. Traders may use the ask size to time their exits or short-selling strategies.
If the ask size is smaller than your sell order, your shares will be sold across multiple bid prices, possibly at lower prices than expected.
Slippage and Ask Size
Slippage and Ask Size is a crucial concept to understand, especially when trading with thinkorswim. Ask size is the amount of shares someone is willing to sell at the best possible ask price.
The ask size is the opposite of bid size, and it plays a significant role in slippage. Slippage refers to the difference between the expected price of a trade and the price at which it is actually executed.
Large orders during periods of low liquidity may be executed at less favorable prices because of the limited availability of shares at the best bid or ask price. This is where ask size comes in – it shows how many shares are available at each price.

Ask size is typically expressed in “lots,” which are usually 100 shares each or 10 shares each for large stock prices. This means that if you're looking to buy a stock, you can use ask size to see what the price and number of shares available are.
Here are some key things to know about ask size:
- Ask size shows how many shares are available at each price.
- Large orders during periods of low liquidity may be executed at less favorable prices due to limited availability of shares.
- Ask size is typically expressed in “lots” of 100 shares each or 10 shares each for large stock prices.
Ask Size in Practice
Ask size is a crucial metric for traders to gauge market sentiment and make informed decisions. Traders closely monitor ask size to time their exits or short-selling strategies, as large sell orders in the ask column can be a cue to sell before the price drops further.
Traders may join the queue when they see a large order on the ask side, anticipating that the demand could push the stock price down. This is a common practice among day traders and market makers.
Large institutional buyers or sellers can significantly impact ask size, influencing the stock's short-term price direction.
Stop Orders

Stop orders can be triggered and turn into market orders at any time, which is why it's essential to understand the bid-ask size at the time of execution.
A small bid size can lead to a lower-than-expected fill price for a stop-loss order.
The bid-ask size at the time of execution becomes crucial in determining the price you'll receive for a stop order.
If there's not enough demand at the stop price level, a stop-loss order could be filled at a much lower price than expected.
Why It Matters
Understanding ask size is crucial because it can give you a glimpse into the overall market sentiment and potential future movements in stock prices.
If the number of asks is substantially greater than the number of bids, it suggests more investors are attempting to sell shares, which may potentially drive the security's price down. This can be a red flag for investors considering buying the stock.

The difference between bid size and ask size can be significant, and it's essential to monitor these numbers to make informed trading decisions.
In options trading, the ask size and bid size can be particularly important, as they can impact the price at which you buy or sell contracts.
Using limit orders in options trading can ensure the best fill price, even if it takes some time to get filled. This is especially true in high volatility environments and illiquid products.
Frequently Asked Questions
What is the difference between bid size and ask size in thinkorswim?
In thinkorswim, the Bid Size column and Ask Size column are used to place different types of orders, with Bid Size related to buying and Ask Size related to selling. Understanding the difference between these two columns is crucial for executing trades effectively in the platform.
Why is the ask higher than the bid?
The ask price is higher than the bid price because market makers set a slightly lower buying price to encourage selling and a slightly higher selling price to make a profit. This price difference is a key aspect of market making, allowing market makers to buy low and sell high.
