Guides
Each guide opens with the answer to the question in its title. Longer pieces include a jump-link contents rail so you can skip to the part you need.
Guides that involve clicking through a real platform interface are only published once we have captured the screenshots ourselves from the official English interface. We do not illustrate steps with recreated or AI-generated mock-ups.
A deposit does not land in the account that trades, and a withdrawal does not leave from it. The three pockets of an OKX login, and the rules that decide when a balance is spendable.
BTC-USDT-SWAP trades in contracts worth 0.01 BTC, BTC-USD-SWAP in contracts worth 100 USD. How to turn a position into coins, notional and margin before sizing it.
Level caps, cache intervals, aggregation and excluded order types mean four venues answer the same question differently. A method for comparing book depth that survives it.
A Bybit stop can close the whole position or a fixed slice of it, trigger on three different prices, and be blocked by reduce-only. What each switch actually does.
Binance and OKX each run two practice environments on separate networks, with different prices and reset rules. Picking the wrong one is a configuration bug, not a preference.
Replacing an order forfeits its place in the queue and costs a rate-limit unit; amending quantity keeps both. The two Binance endpoints and when each is correct.
A Binance depth stream sends changes, not a book. Here is the snapshot-plus-buffer procedure, the gap test that forces a resync, and the limits that break it.
The new form reports proceeds for every sale and basis only sometimes. What covered and noncovered mean, how lots are chosen, and which numbers you still have to supply yourself.
A quote is a price for bearing two risks: inventory and being picked off. How the size on the book follows the maker's position, and why published depth is a sample rather than the queue.
