Composite Print (Consolidated Tape)
The Formal Definition
The unified electronic financial data infrastructure (governed by the Consolidated Tape Association and UTP Plan) that aggregates, timestamps, and reports all executed trades and national quotes (NBBO) across every registered US stock exchange.
Consolidated Tape NBBO = [max_{All Exchanges}(Bid_t), min_{All Exchanges}(Ask_t)] | Timestamped to Sub-Microsecond
Cole Barrett's Reality Check
The Unvarnished Bottom Line"If you are trading stocks using free charting software, you are probably looking at an incomplete picture of the market. Discount brokers often give you quotes from just one regional exchange (like Cboe BZX) and call it a day. Meanwhile, the real institutional market is trading on the Consolidated Tape, seeing liquidity and price moves that your free charts don't even display."

Examining the real numbers for: An active trader submitting a limit order to purchase 500 shares of a stock during an earnings release
| Execution Metric | Direct Consolidated Tape (SIP) Subscriber | Free Single-Exchange Feed User |
|---|---|---|
| Fee / Rate | $1.50/month consolidated data fee | $0 data fee |
| Spread / Buffer | Monitored the true National Best Bid and Offer (NBBO) across NYSE, Nasdaq, ARCA, and regional books | Used a free charting feed that only showed quotes from a single alternative exchange (e.g., Cboe BZX) |
| Execution / Status | Identified an institutional block order resting on a regional exchange at $105.10; routed order directly | The single-exchange feed showed the best ask at $105.25; completely blind to the $105.10 quote on Nasdaq |
| Total Cost / Result | Saved money on execution by using complete, professional market data | Paid more on execution than the cost of a full data subscription |
How Brokers Weaponize This Term
Check your broker's market data subscription terms. If you don't see subscriptions for 'Network A, B, and C' or 'Consolidated Tape (SIP)', your platform is showing you fractional, single-exchange data feeds that don't reflect the full market.

Why do some brokers provide free Level 1 data while others charge for it?
Brokers have to pay monthly access fees to the Consolidated Tape Association for every active user. 'Free' brokers either absorb this cost, monetize it through PFOF, or display partial data from a single free exchange feed like Cboe One.
What is the difference between Tape A, Tape B, and Tape C?
Tape A reports securities listed on the New York Stock Exchange (NYSE); Tape B reports securities listed on regional and alternative exchanges like NYSE Arca and Cboe; Tape C reports all Nasdaq-listed securities.
