Wondering how to read thinkorswim level 2 quotes? Here’s everything you need to know.

When you begin trading, the headline price on the screen is all you need to know – at least you would think so. But as you dive deeper into trading, you will learn about level 2 quotes.

Level II quotes provide you with essential background market information to help make wise investment decisions.

thinkorswim, a trading platform with a reputation for quality tools and resources, provides you with Level II quote data plus support for using that information to your financial advantage.

Introduction To Level II Quotes

thinkorswim is an investment platform offered by the online brokerage TD Ameritrade.

Like other leading platforms, thinkorswim makes real-time level 2 (or level II) quotes available to help savvy investors make smarter choices based on price action – which in turn may signal where stocks are headed next.

What Are Level I and II Quotes?

When working with thinkorswim, you’ll be dealing a lot with Level I and Level II quotes.

Level I quotes provide the basic information you need to know when you are first considering a trading opportunity, including updated bid/ask numbers and the most recent price stats for a tradable stock.

Level I quotes include:

  • Bid price, or the maximum a trader will pay for the stock
  • Bid size, or how many shares are for sale at that price
  • Ask price, or the minimum price at which a trader will sell a stock
  • Ask size, or how many stocks are for sale at that price
  • Last price, or what the stock went for in its most recent trade
  • Last size, or how much stock was involved in the most recent trade

Level II quotes, also known as the order book for NASDAQ, list the top bid and ask prices for virtually every stock on the exchange.

By observing Level II quotes carefully, you can potentially spot attractive trading opportunities.

Level II information consists of:

  • Market maker’s four-character ID
  • Price the trader paid
  • Number of shares traded

These quotes track the trades of market makers, who are actively trading so that you may base your decisions on deeper insights.

How To Use Level II Quotes

You can expect your Level I and Level II quotes from thinkorswim to be accurate.

Because there is no intermediary between the market and your live data feeds, you will not experience delays due to third-party intervention.

With trustworthy data, you can make more informed trading decisions because level 2 quotes are essentially a measure of market liquidity.

As a trader, when you see lots of orders filled on the buy side, the stock may be on the verge of moving lower because sellers are attempting to offload their positions, which is likely to drive share prices lower.

And vice versa, the stock may be heading higher if lots of orders are filled on the sell side because buyers are looking to gobble up stock.

Penny stock traders pay especially close attention to Level II quotes because a single buyer or seller can quickly move the share price of a cheap stock.

By spotting where demand to buy or sell shares is strong, “lines in the sand” can be drawn to give traders more confidence where technical support or resistance on stock charts may sit.

How To Read Level 2 Quotes Example

Trades only take place when buyers and sellers come to an agreement on price.

Let’s pretend we have 5 buyers and 2 sellers of say Amazon stock, or any other stock.

We’ll pretend the share price is $1,950 to begin.

# Shares To BuyBuyersPrice# Shares to SellSellersPrice

As you can see in the table above, Jimmy wants $2,000 before he’s willing to sell but none of the buyers are willing to pay $2,000 so no transaction occurs.

Either Jimmy needs to lower the price he’s willing to offload his shares or one of the buyers needs to boost the price that they are willing to pay.

If a new seller comes into the market and decides to sell shares at the price Ann is willing to pay, then the price will decline to $1,900 from $1,950.

On the other hand, if one of the buyers realizes there are no sellers willing to come down in price they may decide to increase the price they are willing to pay, which causes the share price to rise.

How Charts Help Traders

The charts interface on the thinkorswim platform is versatile, flexible and customizable to help you visualize the specific data you are working with, such as Level I or II market data.

When you create a chart, the app produces a standard bar graph that maps a stock’s progress over the previous 366 days.

You can adjust the time frame, change the appearance and style of the graph or enter new information to produce entirely new perspectives on the stock you are evaluating.

Setting the Time Frame on Charts

Charts are available to show any time frame you select up to a year and a day.

Clicking the Time Frame button above the chart takes you to a choice of “Time,” “Tick” or “Range.”

You can select “Day,” “Intraday” or “Custom” to choose how often the chart will aggregate and display emergent data on the stock.

If you opt for “Tick,” the chart will add a new bar each time the stock reaches a preset number of trades. You can specify any number from 1 → 10,000.

The custom option can show you all past data on the stock up to the present day. Thereafter, the chart will update as each day of trading ends.

Exchanges Supported

thinkorswim offers you access to a full range of exchanges, including:

  • NYSE Amex
  • EDGX
