Everything a trader checks, in one place
Reports that name the problem
Where you make and lose money: by holding time, entry hour, weekday, leverage, direction and coin. Insights in plain words — facts from your trades, not signals.
Charts and the best time to enter
Daily P&L with the cumulative curve, coin focus, win stats and the hours and days that work for you — separately for longs and shorts.
A calendar of your trading
Every day in green or red at a glance, with deposits, withdrawals and Earn transfers marked on the same calendar.
Review trades on your phone
Tag the setup, the mistakes and how you felt while you still remember. Reviews add up to reports: which mistake costs you most, which setup works.
Built so we cannot see your money
- Read-only access

Your journal is encrypted on your device with a key derived from your password. Our server stores only encrypted data.

Requests go from your browser directly to the exchange, not through our server.
- Your devices, your rules
Approve every new device with a number, see the list and close access in one tap.

Questions
Is it safe to give my API key?
Create a key with read-only rights. Buy&Sell checks the rights when you connect it and refuses keys that can trade or withdraw. The key is stored encrypted with your journal.
Which exchanges are supported?
OKX today. Hyperliquid, Bybit and Binance are next; several exchanges can share one journal.
Does it work on a phone?
Yes. Open the site on your phone and add it to the home screen — it works like an app. Desktop and phone share one journal.
Can you see my trades?
No. The journal is encrypted on your device; our server keeps only encrypted files and cannot read them.
How do I pay and cancel?
Plans are paid in USDT for a month or a year; nothing renews automatically. When the paid period ends, the account switches to Basic and your data stays.
Is this investment advice?
No. Buy&Sell shows facts from your own trades and the market. Decisions are yours; trading carries risk of loss.
Does it help with taxes?
The tax report shows each closed trade in your country's currency at the official rate on the close date, with yearly totals and CSV. It is not tax advice.
