How to read the tape: Time & Sales explained

Let me start with a sentence I want you to remember: price tells the story, and the tape reveals the truth.

Here’s what I mean. A lot of traders believe the market is made by moving averages, Fibonacci, MACD — all these indicators. It’s not. The market is made by buyers and sellers, that’s it. Tape reading just means you’re watching the buyers and sellers directly, in real time. Order flow, the tape, Level 2, Level 1 — these are all fancy words for the same thing: looking at what the buyers and sellers are actually doing. So when you read the tape, you’re looking at the most fundamental thing in the market.

I trade live every session on DAS Data Pro, Lightspeed and Bookmap, and the Time & Sales window is open on every screen. Let me show you how I actually read it — and I’ll be honest with you about how long it takes.

The chart is history. The tape is intent.

Your chart shows you what already happened — the past price action. The tape shows you the intent: what the buyers and sellers are doing right now. And the intent is what moves the market next.

Now, very important — I’m not telling you to throw away your charts. Technicals are the primary thing. You mark your levels, your structure, your support and resistance first. Then you add tape reading on top of that. That’s what gives you the real market sentiment. Indicators? They have a place, but honestly they’re the last piece of the puzzle — the least important piece. A moving average reacts after price has already moved; it’s a lagging indicator. The tape is a trend-leading indicator — it shows you the move forming before the candle even prints.

Here’s the way I think about it. Say you trade a break-and-retest, or a bull flag. About 50% of those work and 50% are a fake-out — basically a coin flip. With tape reading, instead of being right half the time, you push the odds into your favour — 75%, 80%. It’s never going to be 100%. Anyone telling you 100% is lying. But moving from 50% to 75% over hundreds of trades — that’s everything.

The three pillars — the complete ecosystem

Most people think the tape is just the Time & Sales window. It’s not. I treat it as a complete ecosystem of three things:

• Level 1 — the surface. The best bid and the best ask. The top of the book.
• Time & Sales — the prints. The live feed of trades that actually executed. And here’s the key: you can’t fake these. The stock market has centralised volume, so a print is a real, done deal.
• Level 2 — the depth. The pending orders sitting in the book above and below price. These can move the market — but you can fake these. Someone places a big order at 100 and pulls it before price ever gets there. So Level 2 is intent, and intent can lie. The prints can’t.

Hold onto that difference. The prints are the truth.

The biggest myth: green means buying, red means selling

This is the one that traps everybody, so let me be clear: the tape shows you aggression, not direction.

There’s a buyer for every seller and a seller for every buyer — every single trade. So a green print does not mean “people are buying,” and red does not mean “people are selling.” The colour tells you who was aggressive:

• Green print = the trade hit the ask. A buyer reached up and took the offer. Think of buying an iPhone — you found the one you want and you’re impatient: “I need it now, I’ll pay the asking price.” That’s green.
• Red print = the trade hit the bid. A seller got urgent: “get me out now, I’ll take whatever the buyer’s offering.” That’s red.

So when you watch the tape, don’t read “green good, red bad.” Read who is the aggressor right now — and then, more importantly, watch what price actually does about it.

What I’m actually watching

You can’t read every print. On a fast name it’s a blur, and a lot of that speed is just algos and noise designed to make you feel a direction that isn’t there. So I filter for a few things.

Size — and remember, big is relative. A big print is one that’s way larger than the normal print size for that specific stock. 50,000 shares is big on NVDA. On Meta or Netflix, 2,000–3,000 might be big. You have to know the name. The whales — the institutions, the funds — are what move the market, because they have the capital. Us placing 100, 200 shares doesn’t move anything.

Printing rhythm — the speed. Every stock has its own normal pace. Tesla and Apple print fast; a slower name like Shopify prints slow. When the tape suddenly speeds up at a level you care about, that’s information. When it goes quiet, that’s hesitation.

Absorption — the read I trust most. Sellers keep hitting the bid at one price, print after print, and price won’t go down. That means somebody is sitting underneath quietly absorbing all of it — a buyer holding the floor. The selling is real, but it’s getting eaten. That’s often exactly where the move flips.

Read the tape AT your levels — that’s the whole thing

The tape on its own is noise. The method I teach — Market DNA — is reading the live tape around the technical levels that already matter on your chart. The chart gives you the spot. The tape and Level 2 tell you, in real time, whether that spot is actually being defended.

So: mark your level. Watch the depth into it on Level 2. Then watch the prints as price arrives — are sellers hitting the bid and getting absorbed, or is the bid vanishing and price slicing through? The tape is one input into the bigger picture of order flow trading, not the whole thing.

A couple of edges most people skip

The open. A lot of pure price-action traders sit out the first five minutes because there’s no candle yet. With the tape you don’t need the candle — you can read buying or selling strength right off the open. I call it my open exception.

Algos. When the market is just chopping in a range, a lot of it is algos. The tape is how you feel that — you see big buyers and big sellers cancelling each other out, and you know to sit on your hands instead of forcing a trade.

How long this really takes

I’ll be straight with you, because most people won’t be. You don’t learn the tape in a weekend. You learn it by watching the same one or two names, every session, for months, until you know their rhythm cold. Every stock is like your sibling — if you pinch your sibling, you know exactly how they’ll react; pinch a stranger and you have no idea. Your job is to turn a few stocks into your family.

The fastest way I know to get there is to record your screen and review it. I record mine every session — I’ve done it for years. I started playing squash recently and I was losing to my friend, so I recorded my games and studied them, and I got better. Same thing here. Watch your recording back at half speed, study how a level got absorbed, then train yourself to spot it at 5x — because when you’re live and emotional, the market feels like it’s moving at 5x even when it’s really at 1x.

And the honest part: reading the tape and being consistently profitable are two different milestones, and the second is much further out — for most people it’s a one-to-two-year project, if it happens at all. Most retail traders lose money. This is education, not financial advice, and the tape is not a crystal ball. It’s the live lens on whether the level in front of you is real.

If you’re wondering whether any of this still works in a market full of algorithms, I answered that honestly here: is tape reading still relevant? Short version — they changed the noise, not the principle. Watch one name, watch it a lot, and the tape stops being noise and starts being information.
