Coinone

Spot trading on the KRW market of the Korean exchange Coinone (API address https://api.coinone.co.kr). It uses REST only, with no market-data or order push. Private endpoints are signed with a Coinone API key (Access Key and Secret Key).

Names and Configuration

exchange.GetName(): Coinone (Spot).

Field	Required

Secret Key	Yes

Trading Pairs and Contract Codes

Pair examples: BTC_KRW, ETH_KRW

Trading pairs are written BASE_QUOTE, quoted in KRW.

Function Support

Not supported (the call fails with an error and returns null): exchange.ModifyOrder, exchange.ModifyConditionOrder, exchange.GetHistoryConditionOrders.

Served through a fallback:

• exchange.GetRecords: Native periods are 1m, 3m, 5m, 10m, 15m, 30m, 1h, 2h, 4h, 6h, 1d, 1w, 1M; other periods are synthesized by the docker.

Notes

• exchange.GetTickers() returns the tickers of all KRW-market pairs; exchange.GetMarkets() returns only the tradable KRW-market pairs (trade_status is 1).
• The amount of a market buy order is the quote currency (KRW) to spend (placed as Coinone's amount); a market sell order uses the base-currency quantity.
• Maker-only (postOnly, limit orders only) orders are supported; the tif (IOC, FOK) option is not and reports an error.
• Conditional orders use Coinone STOP_LIMIT orders and support take-profit and stop-loss; an order price after triggering is required (executing at market once triggered is not supported), and OCO is not supported; conditional orders are canceled through the same endpoint as normal orders.
• The open orders returned by exchange.GetOrders() include untriggered conditional orders (STOP_LIMIT).
• The exchange's completed orders carry no order type, so historical conditional orders cannot be queried.
• When exchange.GetConditionOrders() is called without the symbol argument, take-profit and stop-loss cannot be told apart from the current price, and the conditional orders are returned with the generic condition type.
• exchange.GetHistoryOrders() reads Coinone's completed orders (completed_orders), which include filled orders only, not canceled ones; without limit, at most 100 orders are returned.
