OKX API quant from scratch: from requesting a key to your first order script
Requesting an API key, how to set permissions, what the Passphrase is — and the full run from checking your balance to placing an order in Python (ccxt).
OKX · Quant / strategy trading
Grid bots, copy trading, API scripts — from signing up for OKX and opening API keys to getting your first order through, we break down every step. Every strategy comes with parameters you can follow, code that runs, and the risks you must see clearly.
* The discount follows OKX's currently published rebate / fee rules. Crypto is high-risk; nothing here is investment advice.
# Step one: confirm the API works first, then talk strategy
import ccxt
okx = ccxt.okx({
'apiKey': 'your API Key',
'secret': 'your Secret',
'password': 'your Passphrase', # OKX-specific, don't skip it
})
bal = okx.fetch_balance()
print(bal['USDT']['free']) # → confirm the funds are thereA lot of people get stuck on "which step comes first." We lay it out in the real order, and each step has a hands-on article to match.
Sign up for OKX with referral code OK30001, finish identity verification, and get an account you can trade with.
Create an API key, tick "Trade" only, and never tick "Withdraw" — that's the security floor.
Grid, copy trading, DCA, or your own script? Choose based on how much time you can spend watching the market.
Position sizing, stop-losses, demo account first — survive first, talk returns later.
