bitFlyer

Spot trading on the Japanese exchange bitFlyer (api.bitflyer.jp). Only spot pairs are served (products whose market_type is Spot), not bitFlyer's FX and futures products; the exchange has no K-line or batch ticker endpoint. Conditional orders use bitFlyer parent orders. Access uses an API Key and Secret Key.

Names and Configuration

exchange.GetName(): BitFlyer (Spot).

Field	Required
Access Key	Yes
Secret Key	Yes

Trading Pairs and Contract Codes

Pair examples: BTC_JPY, ETH_JPY

Trading pairs are written BASE_QUOTE, the same form as the bitFlyer native product_code.

Function Support

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

Served through a fallback:

• exchange.GetRecords: The exchange has no K-line endpoint; bars are synthesized by the docker from trades. The first call covers only the few bars spanned by recent trades, and more accumulate with later calls.

Notes

• The amount of a spot market buy order is in the base currency, not a quote-currency amount (orders are placed by bitFlyer size).
• Maker-only (postOnly) orders are not supported; the exchange has no client order ID field, so a custom order ID (clientId) is not supported for regular or conditional orders and fails without sending the order.
• The open-order and open-conditional-order endpoints require a trading pair: without the symbol argument, exchange.GetOrders() and exchange.GetConditionOrders() query the current trading pair only. Without limit both page through and return all open orders.
• exchange.GetHistoryOrders() and exchange.GetHistoryConditionOrders() do not support the since argument (the exchange only pages by order id) and fail when it is given; without it they return the most recent orders, at most 100 by default.
• Conditional orders use bitFlyer parent orders (SIMPLE) and support take-profit and stop-loss (without an order price they execute at market once triggered), not OCO.
• exchange.GetMarkets() gives no price/amount precision or order-size limits (the exchange API does not provide them); those fields are 0.
• The exchange's ticker endpoint has no 24-hour high, low or open price: High and Low in exchange.GetTicker() are filled with the best ask and best bid, and Open is 0.
• The order ID returned on placement is the acceptance ID (starting with JRF), while exchange.GetOrders() and exchange.GetHistoryOrders() give the exchange's internal order ID; both IDs can be used to query and cancel, and the same applies to conditional (parent) orders.
