How to read Level 2 and Time & Sales: bid and ask depth, prints at the bid or ask, absorption, large prints, stacking and pulling, and what the book hides.

Level 2 shows the limit orders waiting at each price: the bids below the market and the offers above it, with the size and the venue or market maker posting each one. Time & Sales, often called the tape, lists every trade that actually printed: time, price, size and, on most platforms, whether it hit the bid or lifted the ask. Scalpers read the two together at a level they planned in advance, looking for absorption, large prints and liquidity that appears or vanishes.

The catch: in US stocks, the book on your screen is only part of the market, because hidden orders, other exchanges and off-exchange trading never show in it. Below: what each screen shows, what to look for, the limits, a practical setup and a worked example on XYZ, a made-up stock. All numbers are hypothetical, and trading carries real risk.

## Level 1, Level 2 and Time & Sales: what each one shows

Level 1 is the top line: the best bid, the best ask, their sizes and the last trade, as explained in the [bid-ask spread](https://uptickflow.com/en/learn/bid-ask-spread) lesson. Level 2 adds depth, the orders resting at the next prices away. Time & Sales adds history: what traded, at what price and in what size. The names you will meet:

- Nasdaq Level 2: each market participant’s best bid and offer on Nasdaq, labeled with a four-letter code called an MPID.
- Nasdaq TotalView: Nasdaq’s full depth-of-book feed, every displayed quote and order at every price on its own book; still one exchange.
- Aggregated books: many brokers merge several exchanges’ displayed quotes into one ladder, labeling each row NSDQ, ARCA, EDGX and so on.
- Time & Sales: the stream of trade reports, including off-exchange trades, which never appear in an exchange book.

## How to read a Level 2 screen

Bids sit on the left, highest first; asks on the right, lowest first. The top rows form the inside market, and the gap between them is the spread. Each row shows a price, a size (in shares or lots of 100, depending on the platform) and who is posting it.

Read the shape, not single numbers. A thin ask above price means little stands in the way; one large offer at a key level or a round number is a wall that buyers must trade through. Judge size against what the stock normally trades: 12,000 shares is a wall in a stock that prints 300 at a time and noise in one that prints 50,000; [relative volume](https://uptickflow.com/en/learn/relative-volume) helps you calibrate.

## How to read Time & Sales

Each line of the tape is a trade, colored by where it printed against the quote: at or above the ask usually means an aggressive buyer lifted the offer; at or below the bid, an aggressive seller hit the bid; in between, a midpoint trade, often off-exchange. The color is inferred from the quote at that instant, so in fast markets it can be wrong.

Watch speed and size rather than single prints. A tape that suddenly accelerates at the ask while the offer shrinks shows buying pressure; a burst of large prints at the bid that fails to push price lower suggests absorption. Off-exchange trades must be reported within 10 seconds, so some prints arrive slightly late. For delta and footprint charts built from the same data, see [order flow trading](https://uptickflow.com/en/learn/order-flow-trading).

## What scalpers look for

None of these is a signal on its own. They matter at a level you marked before the open, as in [key levels for day trading](https://uptickflow.com/en/learn/day-trading-key-levels).

- Absorption: heavy trading at one price that fails to move it, such as sellers hitting a bid that keeps refilling.
- A level that refreshes: displayed size that comes back after it trades, a sign of a reserve or iceberg order; when it stops refreshing and gets taken, price often moves fast.
- Large prints: trades far bigger than normal at a key level, which show interest, not direction.
- Stacking and pulling: size added as price approaches, or removed just before price arrives, as in the drawing below.
- Tape speed: a break on accelerating prints is more convincing than one that drifts through on a few trades.

## The limits: what the book does not show

Hidden and reserve orders. Exchanges such as Nasdaq accept non-displayed orders, and reserve orders that show only part of their size and refill as it trades. The 500 shares you see may sit on top of thousands you do not.

Fragmentation. US stocks trade on more than a dozen exchanges and off-exchange, at wholesalers that fill retail orders and in alternative trading systems often called dark pools. Cboe’s review of 2025 puts off-exchange trading at 50.6% of consolidated volume, the first year above half; those trades print on the tape but never sat in a book you could see.

Spoofing. Placing orders you intend to cancel, to fake supply or demand, is illegal: the Dodd-Frank Act of 2010 banned it explicitly on US futures exchanges, and the SEC has charged layering in stocks as manipulation under the Securities Exchange Act. It still happens, so treat displayed size as information, not commitment.

## A practical tape-reading setup

Keep it narrow: one or two liquid stocks, a few planned prices, and a chart for context. The [scalping strategy](https://uptickflow.com/en/learn/scalping-strategy) lesson covers which names and costs suit this kind of trading.

1. Pick one or two liquid stocks or ETFs with a one-cent spread.
2. Watch Level 2 and the tape only near a level you marked before the open, with a 1- or 5-minute chart beside them; see the [best timeframe for scalping](https://uptickflow.com/en/learn/best-timeframe-for-scalping).
3. Highlight large prints on Time & Sales, sized for that stock.
4. Write down what confirms the trade, such as an offer that stops refreshing and gets lifted, and what cancels it.
5. Take the stop and the target from the chart: the tape decides when, not where.
6. Skip the trade if the spread is more than about a tenth of your stop.

## Worked example: an offer that refreshes, then breaks (hypothetical)

XYZ is a made-up stock trading just under $50.00, a round number and yesterday’s high. At 10:12 a.m. ET the book shows 12,000 shares offered at $50.00, far above the usual 1,000 or so. Over two minutes about 20,000 shares print at $50.00 at the ask, yet the offer still shows 11,000 and nothing trades higher: a seller is absorbing the buyers. No trade yet.

At 10:16 the offer drops to 1,500 and is lifted; prints at $50.01, $50.02 and $50.03 come quickly, and the best bid steps up to $50.00. That is the trigger; the stop and the target come from the chart.

1. Entry: $50.03, with a limit order; see [order types](https://uptickflow.com/en/learn/order-types).
2. Stop: $49.88, under the $50.00 level and the last higher low at $49.92. Risk: $0.15 a share.
3. Target: $50.33, just under the pre-market high at $50.35. Reward: $0.30, or 2R before costs.
4. Size: a $25,000 account risking 0.2% per scalp accepts $50; with about $0.02 of round-trip costs, $50 ÷ ($0.15 + $0.02) = 294 shares, as the [position size calculator](https://uptickflow.com/en/learn/position-size-calculator) shows.
5. Result: about 294 × ($0.30 − $0.02) = $82, roughly +1.6R after costs, at the target; 294 × $0.17 = about $50, or −1R, at the stop.
6. Early exit: if the offer at $50.00 reappears right after the entry, the break has failed; selling near $49.97 costs about $0.08 a share with costs, roughly half of 1R.

## Common tape-reading mistakes

Most problems come from trusting the screen too much:

- Watching the tape all day without levels, so every print becomes a reason to trade.
- Treating displayed size as real support or resistance.
- Chasing a large print, which shows interest, not the winner.
- Trading thin stocks, where a few orders paint the book.
- Paying for depth data before having a written plan: Level 2 sharpens timing, it does not create an edge.

## Key takeaways

- Level 2 shows displayed limit orders by price and venue; Time & Sales shows the trades that actually printed, with their size and side.
- Read them together at a planned level, looking for absorption, a refreshing bid or offer, large prints, stacking and pulling, and tape speed.
- The US stock book is incomplete: hidden and reserve orders, other venues and off-exchange trading, over half of 2025 volume, never show in it, and spoofing is illegal but happens.
- Let the tape decide when to act and the chart decide where the stop and the target go, and size every scalp with its costs included.

## FAQ

**What is the difference between Level 1 and Level 2?**

Level 1 shows the best bid, the best ask, their sizes and the last trade. Level 2 adds depth: the orders waiting at the next prices, with the venue or market maker posting each one.

**What is Nasdaq TotalView?**

Nasdaq’s full depth-of-book data feed, showing every displayed quote and order at every price on Nasdaq’s own book. It is more complete than Nasdaq Level 2 but still covers one exchange, without hidden orders or other venues.

**What do green and red mean on Time & Sales?**

On most platforms green marks a trade at or above the ask, usually an aggressive buyer, and red a trade at or below the bid, usually an aggressive seller. The colors are inferred from the quote at that instant, so treat them as estimates.

**Is Level 2 worth it for beginners?**

Only once you have a plan with levels, stops and size. Level 2 can sharpen timing at a level; it cannot tell you where price will go, and much of the real liquidity never appears on it.
