Time and sales

1. Time and Sales

Introduction

Time and Sales (often abbreviated as T&S) is a fundamental data feed used by traders, particularly day traders and scalpers, to analyze real-time market activity. It provides a chronological record of every completed trade, displaying the price, quantity, and time of each transaction. Understanding Time and Sales is crucial for gaining insights into market depth, identifying potential price movements, and confirming trading signals generated by other technical analysis tools. This article aims to provide a comprehensive overview of Time and Sales for beginners, covering its components, interpretation, applications, and how it complements other trading strategies.

What is Time and Sales Data?

At its core, Time and Sales is a tick-by-tick record of executed trades. Unlike a standard chart which displays price movements over time, T&S focuses on *when* and *at what price* each trade actually happens. This raw data is incredibly granular and can reveal subtleties in market behavior that are not apparent on traditional charts. Each line in a Time and Sales feed typically represents a single trade and contains the following information:

• **Time:** The exact time the trade was executed (usually down to the millisecond).
• **Price:** The price at which the trade was completed.
• **Size (Volume):** The number of shares, contracts, or lots traded in that transaction.
• **Exchange:** The exchange where the trade occurred (e.g., NYSE, NASDAQ, CBOE). Important for understanding liquidity fragmentation.
• **Condition Codes:** These codes provide additional information about the trade, such as whether it was a regular trade, an opening trade, a closing trade, or a large block trade. Condition codes vary by exchange.
• **Trade ID:** A unique identifier for each trade.

This information is streamed in real-time to trading platforms, providing traders with an immediate view of market activity. The data is typically presented in a tabular format, allowing for easy scanning and analysis.

Interpreting Time and Sales Data

Simply looking at a stream of numbers isn't enough. Effective interpretation of Time and Sales requires understanding how to identify patterns and anomalies. Here are some key concepts:

• **Hit Bids & Pulling Offers:** When a trade occurs at the best ask price (the lowest price a seller is willing to accept), it's called a "hit ask" or "pulling offers." This indicates strong buying pressure. Conversely, when a trade occurs at the best bid price (the highest price a buyer is willing to pay), it’s a “hit bid” and suggests strong selling pressure. These hits can signal short-term reversals or continuations of trends.
• **Speed and Frequency:** The speed at which trades are occurring and the frequency of transactions can be indicative of market momentum. Rapid-fire trades at consistent prices suggest strong conviction, while slower, more sporadic trading can indicate indecision.
• **Size Distribution:** The size of trades provides clues about the participants involved. Large block trades (often identified by condition codes) can signal institutional activity and potentially trigger significant price movements. Small, retail-sized trades are often less impactful individually but can collectively contribute to overall market direction. Analyzing the distribution of trade sizes helps determine if the market is driven by institutional or retail traders.
• **Imbalances:** Imbalances occur when there’s a significant disparity between the number of buyers and sellers at a particular price level. For example, if multiple trades are hitting the ask price but few are hitting the bid price, it suggests a bullish imbalance. Conversely, more hits on the bid indicate bearish pressure. Imbalances are often short-lived but can provide valuable trading opportunities.
• **Sweeps:** A sweep occurs when a large order executes across multiple price levels on either the bid or ask side. This indicates aggressive buying or selling and can often lead to momentum. Sweeps suggest that a large participant is willing to pay a premium (for buying) or accept a discount (for selling) to get their order filled quickly.
• **Prints:** Each trade executed is referred to as a "print." Analyzing the sequence of prints, their size, and their relationship to the bid and ask prices, helps traders assess the underlying market sentiment.
• **Delta:** A crucial metric derived from Time and Sales, Delta represents the difference between the volume of buyers and sellers in a given period. Positive Delta indicates more buying than selling, while negative Delta indicates more selling than buying. Analyzing Delta can help identify short-term momentum shifts. See Delta Trading.
• **Absorption:** When a large order consistently hits the bid or ask without causing a significant price movement, it's considered absorption. This suggests that strong buyers or sellers are preventing the price from moving against them. Absorption often precedes a breakout or reversal.

Time and Sales vs. Level 2 Data

Time and Sales is often confused with Level 2 data. While both provide insights into market activity, they are distinct. Level 2 data displays the *best bid and ask prices* from multiple market makers (ECNs and exchanges). It shows the depth of the order book, revealing the quantity of shares available at each price level. Time and Sales, on the other hand, shows *executed trades*, providing a historical record of what actually happened.

Think of it this way: Level 2 shows *intent* (what buyers and sellers are offering), while Time and Sales shows *action* (what buyers and sellers are actually doing). Both are valuable, and many traders use them in conjunction. Level 2 helps anticipate potential price movements, while Time and Sales confirms those movements and provides additional context. Order Flow analysis often combines both.

Applications of Time and Sales in Trading

Time and Sales data is utilized in a wide range of trading strategies:

• **Scalping:** Scalpers rely heavily on Time and Sales to identify short-term imbalances and profit from small price movements. They look for rapid-fire prints, sweeps, and hits to the bid/ask to execute quick trades. Scalping Strategies.
• **Day Trading:** Day traders use Time and Sales to confirm chart patterns, identify breakout opportunities, and gauge the strength of trends. They often combine it with candlestick patterns and volume analysis.
• **Momentum Trading:** Time and Sales helps identify stocks with strong momentum by revealing consistent buying or selling pressure. Traders look for large sweeps and sustained hits to the ask.
• **Reversal Trading:** Identifying absorption and imbalances can signal potential reversals. Traders look for signs that the current trend is losing steam and prepare to enter a trade in the opposite direction.
• **Auction Market Theory:** Time and Sales supports the principles of Auction Market Theory by revealing the dynamics of supply and demand. Analyzing the prints and imbalances helps understand where the market is currently "auctioning" the price.
• **VWAP (Volume Weighted Average Price) Analysis:** While VWAP is typically calculated on a chart, Time and Sales provides the underlying data used for the calculation, allowing traders to refine their VWAP strategies.

Combining Time and Sales with Other Indicators

Time and Sales is most effective when used in conjunction with other technical indicators and analytical tools:

• **Volume:** Confirming Time and Sales signals with volume is crucial. Strong volume during a sweep or imbalance reinforces the validity of the signal. See Volume Spread Analysis.
• **Moving Averages:** Time and Sales can help confirm breakouts above or below moving averages. A strong surge in volume and positive Delta during a breakout increases the likelihood of a sustained move.
• **Relative Strength Index (RSI):** Time and Sales can identify divergences between price and RSI, signaling potential reversals.
• **MACD (Moving Average Convergence Divergence):** Time and Sales can confirm MACD crossovers and identify momentum shifts.
• **Fibonacci Retracements:** Time and Sales can help identify areas of support and resistance based on Fibonacci levels.
• **Bollinger Bands:** Time and Sales can confirm breakouts from Bollinger Bands and identify volatility contractions.
• **Ichimoku Cloud:** Time and Sales can validate signals generated by the Ichimoku Cloud indicator.
• **Support and Resistance Levels:** Time and Sales can reveal how the market is reacting to key support and resistance levels. Strong buying pressure at support or selling pressure at resistance confirms the validity of those levels.
• **Pivot Points:** Analyzing Time and Sales around daily pivot points can offer insights into potential trading opportunities. Pivot Point Trading.
• **Order Book Heatmaps:** Visualizing order flow data with heatmaps, derived from Time and Sales and Level 2, can provide a clearer picture of market sentiment.
