# The Best Crypto Exchange for Day Trading in 2026, Ordered by Measured Depth

Updated: 24 September 2026 — Tested: 22 September 2026 — Session Log staff

Ordered by depth, the best crypto exchange for day trading here is edgeX: a median $29.3 million rested within ten basis points of mid on its BTC perpetual through the session ending 22 September 2026, against $866,108 on the thinnest book here. Leverage turns one bad fill into a day of gains, so size the order to the book.

## Weights and scoring range

cost 30 · liquidity 30 · custody 15 · security 15 · coverage 5 · access 5. Scored out of 25 on one formula for the whole site, fixed 22 September 2026: https://coinlen.com/how-we-rate

## Standings at the close

The sequence comes from one column only: median dollars resting within ten basis points of the mid price on each venue's BTC perpetual. Who is in the column comes from the register, which admits a venue when its entry tier takes five basis points or less to cross. Aevo is outside it on price, and Lighter and Paradex are outside it although they charge nothing, because each pays for that zero with 300 ms of added delay on the order that carries it. The score beside the depth is the site total.

| # | Venue | Depth within 10 bps | Score of 25 | Maker / taker | Perp markets | Model |
|---|---|---|---|---|---|---|
| 1 | edgeX | $29.3 million | 18.4 | 0.040% / 0.045% | 172 | Hybrid |
| 2 | EVEDEX | $18.5 million | 16.3 | 0.015% / 0.045% | 52 | Hybrid |

| 6 | dYdX | $866,108 | 14.3 | 0.010% / 0.050% | 78 | App-chain, validator-held book |

Facts as of 18 September 2026; fees are the entry tier on the BTC perpetual. Access differs by country.

## Notes taken during the session

1. A $1 million market order cost 0.23 bps against the deepest book on this page and 10.90 bps against the thinnest — about $23 against $1,090.
2. Cheap schedule, dear fill: dYdX charges 0.050% taker and its book cost 6.93 bps on $100,000, about $69.
3. Depth and the total disagree: Extended leads the score and reads fourth on the book; EVEDEX reads second at $18.5 million.

## The log, entry by entry

### 1. [edgeX](https://pro.edgex.exchange) — the book that took a million dollars quietly

18.4 of 25.


The deepest book on this page barely moved: 0.02 bps on a $10,000 market order
and 0.23 bps on a $1 million one, about $23 on the larger trade.
127 readings stand behind this row; the shortest run on the page carries
53.

- Works: Smallest impact here at all three order sizes; Six audits, and an on-chain route out past the operator.
- Falls short: Auto-deleveraging can close part of a winning position; Liability capped at $100 or three months of fees.
- Not for: traders posting resting orders, at 0.040% maker.

### 2. EVEDEX — a deep book on a short list of markets

16.3 of 25.


Second on the book here, and the impact holds to size: 2.06 bps on $10,000 and
2.75 bps on $1 million. Matching happens off the chain on a central order
book, and the settled record of it lands on Arbitrum (EVEDEX trading terms and documentation, 18 September 2026).
CoinMarketCap published open interest of
$704.9 million on 22 September 2026.

- Works: Impact that barely moves with size, 2.06 bps at $10,000 and 2.75 bps at $1 million; A wallet signature opens an account; cross margin in USDT.
- Falls short: Positions reach Arbitrum in accumulated batches, not trade by trade; 52 perpetual markets against hundreds elsewhere, and no spot market; No bug bounty programme listed on CertiK Skynet.
- Not for: traders wanting an exit past the operator, and UK retail clients.

### 3. [Aster](https://www.asterdex.com) — the tightest quote, and a book that thins behind it

18.6 of 25.


The tightest median spread here, 0.01 bps, on a book that
steepens behind the touch: 0.09 bps on $10,000 against 0.37 bps on
$100,000, about 4 times the rate for ten times the size, where four books here charged the
same at both.

- Works: A 0% maker fee on the tightest quote of the six; 578 perpetual markets, the longest list here.
- Falls short: Audits cover the vault and earn contracts, not the matching engine; Terms reserve the right to require identity verification.
- Not for: traders working large clips who stop reading at the spread.

### 4. [Extended](https://extended.exchange/) — the cheapest schedule on a thinner book

19.3 of 25.


0% maker / 0.025% taker flat is $5.00 on a $10,000 round trip against
$9.00 at the head of this page. The book behind it is a quarter as deep as edgeX's,
at 0.77 bps on $1 million.

- Works: Cheapest paid taker schedule here, with no volume tier to climb; A bug bounty paying up to $500,000.
- Falls short: 278 of its 325 markets carry no public order book; Large stablecoin withdrawals cross a third-party bridge, up to four hours.
- Not for: traders pushing six figures through one market order.

### 5. [Hyperliquid](https://hyperliquid.xyz) — the largest venue here, fifth on our own reading

16.6 of 25.


$8.7 billion of open interest against $1.4 billion on the next largest, as
CoinMarketCap published them on 22 September 2026, and still fifth on the book. Size is where it
answers, at 0.71 bps on $1 million.

- Works: Second lowest impact here on a $1 million order; A bug bounty paying up to $1 million.
- Falls short: The audits it lists cover the 2023 bridge contract, not the chain software; Auto-deleveraging can close a profitable position when an account goes negative.
- Not for: traders who want its trading code covered by an audit.

### 6. [dYdX](https://www.dydx.xyz) — where thin starts to cost real money

14.3 of 25.


The order book lives in each validator's memory and the matches go to its own chain. The cost shows
at the touch: a median spread of 1.69 bps, then 6.93 bps on
$100,000 and 10.90 bps on $1 million, about $1,090 on one leg.

- Works: The book is held by the chain's validators, not by one operator; A bug bounty paying up to $1,000,000, run since 8 May 2026.
- Falls short: Withdrawals are rate-limited and gated after an outage; Deleveraging falls on randomly chosen profitable counterparties.
- Not for: market orders at six figures.

## What the books looked like while we watched

BTC perpetual books polled six times an hour until the log closed on 22 September 2026; medians of every successful snapshot.

| Venue | $10,000 round trip | Spread | Depth, 10 bps | Impact, $100,000 | Snapshots |
|---|---|---|---|---|---|
| edgeX | $9.00 | 0.04 bps | $29.3 million | 0.02 bps | 127 |
| EVEDEX | $9.00 | 4.12 bps | $18.5 million | 2.06 bps | 126 |
| Aster | $8.00 | 0.01 bps | $14.9 million | 0.37 bps | 128 |
| Extended | $5.00 | 0.12 bps | $7.8 million | 0.06 bps | 53 |
| Hyperliquid | $9.00 | 0.12 bps | $7.0 million | 0.06 bps | 128 |
| dYdX | $10.00 | 1.69 bps | $866,108 | 6.93 bps | 128 |

## Two ways of paying for the same trade

Taker schedules on the register span two and a half basis points a side; the books span far more.
Both bills below sit on the same $100,000 position, opened and closed with market orders, for four
venues taken from the two ends of the list.

| Venue | Fee, both legs | Fill, both legs | Together |
|---|---|---|---|
| Extended | $50.00 | $1.20 | $51.20 |
| edgeX | $90.00 | $0.40 | $90.40 |
| EVEDEX | $90.00 | $41.20 | $131.20 |
| dYdX | $100.00 | $138.60 | $238.60 |


The fill column is our own median impact at that size. dYdX publishes a taker rate within half a
basis point of edgeX's and still cost about 2.6 times as much all in, because the book behind
it held $866,108 inside the band against $29.3 million.

## How the session was run

Every public book on the list was read every 10 minutes through the session printed with the book
readings, from one machine, and the median of the successful readings is the depth column that sets the
sequence. Impact is what such an order would have paid against the book as it stood, averaged over the
buy and sell sides. Fees, market counts and audit records come from each venue's own
documentation, read on 18 September 2026. The weights are on [how we rate](/how-we-rate). No accounts
were opened and no orders placed. Placement here is paid for.

Read this as one instrument in one window. The figures are BTC books, not the smaller markets on each
venue. The window is one session ending on 22 September 2026, polled
from one machine on one network path. 127 readings stand behind a typical row and
53 behind the shortest run.
Depth moves with the hour, so another session would print different figures and possibly a different
sequence in the thin half. ApeX Omni is on the register and off this page; its book is
read on the [venue list](/crypto-day-trading-platform-list).

## FAQ

### What is the best crypto exchange for day trading?

On the measurement this page is ordered by, edgeX: a median $29.3 million resting within ten basis points of mid on its BTC perpetual through the session ending 22 September 2026. On the six-criterion total this desk uses, Extended leads instead. Fills or fees: whichever limits the session is the one that decides.

### How much liquidity do you need to day trade Bitcoin?

More than the order size, and by a wide margin. A $100,000 market order met books here holding between $866,108 and $29.3 million within ten basis points, and paid between 0.02 bps and 6.93 bps for it. Read the depth before you read the fee schedule.

### What is price impact in crypto trading?

The distance between the average price a market order fills at and the mid price it saw when it was sent. It is what the book charges you, on top of the fee. Here a $1 million order ranged from 0.23 bps to 10.90 bps, and one of the six filled less than nine tenths of it.

### Does a tight spread mean a deep order book?

No. Aster held the tightest median spread here at 0.01 bps on $14.9 million of resting depth, while edgeX quoted a wider 0.04 bps on $29.3 million, twice the size inside the band. The spread is the price of the first contract; the depth is the price of the rest of the order.

### Why did my market order fill at a worse price than I saw?

Because it takes the resting orders from the top of the book downwards until it is full, and only the first of them sits at the price you saw on screen. The thinner the book, the further down it eats: 6.93 bps on a $100,000 order against the thinnest book on this page.

### Which venue had the lowest slippage on a large order?

edgeX, on our readings: 0.23 bps on a $1 million market order, against 0.71 bps on Hyperliquid and 10.90 bps on dYdX. That is roughly $23 against $1,090 on the same trade. All three are medians of ten-minute readings from the session ending 22 September 2026.

### Why are the zero-fee venues not on this page?

Because the register reads what a crossing costs, and neither zero is one. Lighter's free Standard account carries its own published taker latency of 300 ms, and Paradex prices retail orders at nothing only behind a 300 ms speed bump. A free trade that arrives late is not free to a trader working the same day.

### How do you measure order book depth?

Take the mid price between the top bid and the top ask, then add up the dollar value of every resting order within ten basis points of it on both sides. We read every book that way every 10 minutes through one session of readings and published the median.

### Does order book depth change during the day?

Yes, and this page does not measure that. Every figure here comes from one session of readings ending on 22 September 2026, a single block of the trading day. A session run at another hour would print different numbers, and possibly a different order in the thin half.

### Can you day trade on a decentralized exchange?

Every venue here settles on a chain and opens with a wallet signature, and five of the six filled a $1 million market order out of the book we read. EVEDEX matches orders off-chain and settles them on Arbitrum; Hyperliquid keeps its book on the chain itself.
