For crypto traders · spot & perps

Your mistakes have a price. See it in $.

Crypto never closes, so your mistakes never stop compounding — the revenge long an hour after a liquidation, the perp three sizes too big, the funding that bled a winner into a loss. PnL Book journals your spot and perpetual trades from a Binance, Bybit or Coinbase CSV or a screenshot of any exchange, and prices every broken rule in dollars.

The price of a market that never sleeps

A market that never closes is a mistake that never stops compounding.

Equities give you a bell. Crypto gives you nothing — no close, no cooldown, no weekend to reset. The account doesn’t die from a bad thesis; it dies from the trades you took because the screen was still open: the revenge long an hour after a liquidation, the perp doubled after two green candles, the winner you rode into a funding bill because you didn’t want to close it at 3am.

PnL Book is a trading journal built around that fact. Tag the trades that broke your rules and it totals what each habit cost in dollars — funding included. Revenge trading: −$1,840 this month is not a feeling; it’s the exact slice of your book one habit ate, priced in the same USD your positions settle in, whether it’s spot or a perp.

How it works

CSV or screenshot in. Mistakes priced. Coach every week.

  1. A CSV or screenshot in

    Export your trade history from Binance, Bybit or Coinbase and upload the CSV, or drop a screenshot of any exchange’s order-history screen. The AI reads every fill, flags low-confidence fields for your review, and skips duplicates — nothing saves until you commit.

  2. Every mistake priced in $

    Tag the trades that broke your rules — revenge longs, oversized perps, funding you sat through — and each habit gets a running total in dollars. Perp funding is folded into the trade’s fees, so the number you see is the true, all-in cost.

  3. A weekly coach letter

    Every week: what worked, what leaked, and the process fix for the days ahead — every claim cited from your own ledger. Never tips, never signals, never a view on where a coin goes next.

Exchanges

Import from the big exchanges — or a screenshot of any of them

BinanceBybitCoinbaseOKXScreenshot any exchange

Binance, Bybit and Coinbase have a direct CSV import; OKX and anything else works from a screenshot. Exchange exports are stamped in UTC and PnL Book keeps them that way, so your ledger reads the same wherever you trade from — one clock, no timezone to set. If your exchange isn’t on the list, a screenshot of the order-history screen still works: the AI reads the trades out of the pixels.

Spot & perpetuals

Spot and perps in one book, funding priced in

Symbols are canonical and unambiguous: spot reads BTCUSDT, a perpetual reads BTCUSDT.PERP. Common exchange spellings — BTC/USDT, BTC-USDT, XBTUSDT, BTCUSD.P — all normalise to the same thing, so a coin is one line in your book no matter which exchange it came from.

Perpetuals carry funding, and funding is a real cost. PnL Book folds each position’s funding payments into that trade’s fees, so a perp you held through three funding windows shows its true net — not a rosy P&L with the bleed hidden in your wallet history.

  1. Spot settles BASE+QUOTE, e.g. BTCUSDT — USDT, USDC and USD are one-to-one.
  2. Perps append .PERP, e.g. ETHUSDT.PERP, and never carry an expiry.
  3. Funding folds into fees, so the net you see is the all-in cost of the position.

What we won’t promise

PnL Book won’t predict a coin’s price, won’t signal entries, and won’t make you profitable — anyone promising that in crypto is selling something else. It’s a journal: it shows you, with your own numbers, which habits are bleeding your book, so the discipline a 24/7 market demands is something you can see and price rather than guess at. PnL Book is not affiliated with any exchange, and gives no investment advice.

FAQ

Questions crypto traders actually ask

Which exchanges does PnL Book support?

Import a trade-history CSV straight from Binance, Bybit or Coinbase and your fills, fees and timestamps come in automatically. For OKX or any other exchange — desktop or mobile app — upload a screenshot of your order history and the AI reads the numbers off the screen, so there is no exchange API key to hand over and nothing to break when an exchange changes its export.

Does it handle perpetual futures and funding?

Yes. Perps are journaled alongside spot, and each perpetual's funding payments are folded into that trade's fees, so the net cost you see is the true cost — entry, exit, trading fees and funding together. Funding bleed on a position you held too long shows up in dollars instead of hiding in your wallet history.

How does PnL Book price my mistakes in dollars?

USDT, USDC and USD are treated one-to-one, so every position settles in US dollars with no conversion guesswork. Tag the trades where you broke your own rules — a revenge long after a liquidation, an oversized perp, holding through funding — and PnL Book totals what each habit cost across your history, priced in the same dollars your account settles in.

Do you send trade signals or price predictions?

No. PnL Book is a journal and analytics tool for trades you have already taken. It never tells you what to buy or sell, never predicts a coin's price, and never sends signals — it reads your own past decisions back to you and prices the ones that leaked money.

Is my exchange data safe?

PnL Book never connects to your exchange and never asks for an API key or password. You import from a CSV export or a screenshot — that is the entire surface area. Every account settles in USD, and you can export your full history as CSV whenever you like.

The market never closes. Your leaks shouldn’t hide.

Get your spot and perp trades into PnL Book in under a minute — then see, in dollars, what your own mistakes cost, funding and all.
