currency: 'USDT', // optional startAt: 1723550000, // optional endAt: 1723557472, // optional currentPage: 1, // optional pageSize: 100, // optional }); ``` --- ### Trade #### General info Futures are contracts, not currencies. In the futures symbols list you will see a "multiplier" field for each of the symbols. Each contract is equal to Multiplier x Size. For example click on this endpoint and get a symbol info for XRPUSDTM: https://api-futures.kucoin.com/api/v1/contracts/XRPUSDTM In the object, find the "multiplier" value. ```js // In your code, you can fetch it like this const symbolInfo = await client.getSymbol({ symbol: 'XRPUSDTM' }); const multiplier = symbolInfo.data.multiplier; ``` E.g. if multiplier is 10(what you can see from the endpoint), that means each SIZE is 10 XRP. So if XRP is currently at $0.5, then each 1 contract (size 10) is going to cost $5.00 size = (Funds x leverage) / (price x multiplier) ```js const XRPPriceExample = 0.5; const leverage = 5; const fundsToTradeUSDT = 100; const costOfContract = XRPPriceExample * multiplier; const size = (fundsToTradeUSDT * leverage) / costOfContract; console.log(`Size: ${size}`); ``` The trade amount indicates the amount of contract to buy or sell, and contract uses the base currency(USD contracts e.g. XBTUSDM) or lot( USDT contracts e.g. XBTUSDTM) as the trading unit. The trade amount must be no less than 1 lot for the contract and no larger than the maxOrderQty. It should be a multiple number of the lot, or the system will report an error when you place the order. E.g. 1 lot of XBTUSDTM is 0.001 Bitcoin, while 1 lot of XBTUSDM is 1 USD. You can get info about any contract on the link: https://api-futures.kucoin.com/api/v1/contracts/****\_\_**** - just replace the empty space with the symbol of the contract. Here are function examples using the Futures Create Order endpoint: #### Market Short ```js // A MARKET SHORT of 2 contracts of XBT using leverage of 5: const marketShort = futureTransfers.submitOrder({ clientOid: '123456789', leverage: '5', side: 'sell', size: 2, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'market', }); ``` #### Market Long ```js // A MARKET LONG of 2 contracts of XBT using leverage of 5: const marketLong = futureTransfers.submitOrder({ clientOid: '123456789', leverage: '5', side: 'buy', size: 2, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'market', }); ``` #### Limit Short ```js // A LIMIT SHORT of 2 contracts of XBT using leverage of 5: const limitShort = futureTransfers.submitOrder({ clientOid: '123456789', leverage: '5', price: '70300.31', side: 'sell', size: 2, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'limit', }); ``` #### Limit Long ```js // A LIMIT LONG of 2 contracts of XBT using leverage of 5: const limitLong = futureTransfers.submitOrder({ clientOid: '123456789', leverage: '5', price: '40300.31', side: 'buy', size: 2, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'limit', }); ``` On any "close position" action, if you specify a SIZE=0 or leave off the SIZE parameter, then it will close the whole position, regardless of the size. If you specify a SIZE, it will close only the number of contracts you specify. If closeOrder is set to TRUE, the system will close the position and the position size will become 0. Side, Size and Leverage fields can be left empty and the system will determine the side and size automatically. #### Market close ```js // A MARKET CLOSE POSITION example: const marketClose = futureTransfers.submitOrder({ clientOid: '123456789', closeOrder: true, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'market', side: 'sell', size: 0, }); ``` #### Limit close ```js // A LIMIT CLOSE of a LONG example: const limitCloseLong = futureTransfers.submitOrder({ clientOid: '123456789', leverage: '5', price: '70300.31', closeOrder: true, side: 'sell', size: 2, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'limit', }); // A LIMIT CLOSE of a SHORT example: const limitCloseShort = futureTransfers.submitOrder({ clientOid: '123456789', leverage: '5', price: '40300.31', closeOrder: true, side: 'buy', size: 2, symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'limit', }); ``` #### Stop loss ```js // A STOP LOSS example for a LONG position: const stopLossLong = futureTransfers.submitOrder({ clientOid: '123456789', closeOrder: true, stop: 'down', stopPrice: '40200.31', stopPriceType: 'TP', symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'market', }); // A STOP LOSS example for a SHORT position: const stopLossShort = futureTransfers.submitOrder({ clientOid: '123456789', closeOrder: true, stop: 'up', stopPrice: '40200.31', stopPriceType: 'TP', symbol: 'XBTUSDTM', timeInForce: 'GTC', type: 'market', }); ``` ##### Place Multiple Orders ```js //request const orders = [ { clientOid: '5c52e11203aa677f33e491', side: 'buy', symbol: 'ETHUSDTM', type: 'limit', price: '2150', leverage: '1', size: 2, }, { clientOid: 'je12019ka012ja013099', side: 'buy', symbol: 'XBTUSDTM', type: 'limit', price: '32150', leverage: '1', size: 2, }, ]; futuresClient.submitMultipleOrders(orders); ``` #### Cancel Order ```js futuresClient.cancelOrderById({ orderId: 'orderId' }); futuresClient.cancelOrderByClientOid({ clientOid: 'clientOid' }); ``` #### Cancel all orders for specific symbol ```js futuresClient.cancelAllOrders({ symbol: 'XBTUSDTM' }); futuresClient.cancelAllStopOrders({ symbol: 'XBTUSDTM' }); ``` ### Trade/Order/Positions Management #### Fetching orders ```js // Get open orders futuresClient.getOrders({ status: 'active' }); // Get closed orders futuresClient.getOrders({ status: 'done' }); // Get Untriggered Stop Orders futuresClient.getStopOrders({ type: 'limit' }); // Get List of Orders Completed in 24h futuresClient.getRecentOrders(); // Get Details of a Single Order by ClientOrderId futuresClient.getOrderByClientOrderId({ clientOid: 'clientOid' }); // Or By OrderId futuresClient.getOrderByOrderId({ orderId: 'orderId' }); ``` #### Fills ```js // Get Specific Fills futuresClient.getFills({ type: 'market' }); // or search for all futuresClient.getFills({}); // Recent Fills from last 24 hours futuresClient.futuresRecentFills({ symbol: 'ETHUSDTM' }); // Or Search All futuresClient.futuresRecentFills({}); // Active Order Value Calculation futuresClient.getOpenOrderStatistics({ symbol: 'ETHUSDTM' }); ``` #### Positions ```js // Get Position Details futuresClient.getPosition({ symbol: 'ETHUSDTM' }); // Get Position List futuresClient.getPositions({ currency: 'USDT' }); // Or Search All futuresClient.getPositions(); // Get History Positions futuresClient.getHistoryPositions({ symbol: 'ETHUSDTM' }); ``` ## Websocket For Websocket examples, please refer to these links: - [Spot Public Websocket](https://github.com/tiagosiebler/kucoin-api/blob/master/examples/ws-spot-public.ts) - [Spot Private Websocket](https://github.com/tiagosiebler/kucoin-api/blob/master/examples/ws-spot-private.ts) - [Futures Public Websocket](https://github.com/tiagosiebler/kucoin-api/blob/master/examples/ws-futures-public.ts) - [Futures Private Websocket](https://github.com/tiagosiebler/kucoin-api/blob/master/examples/ws-futures-private.ts) ## Community group If you need help, something is wrong/missing or you have suggestions, please join our [Node.js Traders](https://t.me/nodetraders) community group on Telegram and let us know! ================ File: examples/kucoin-SPOT-examples-nodejs.md ================ # **KuCoin SPOT API Examples** - Node.js, JavaScript & Typescript SDK for Kucoin REST APIs & WebSockets <p align="center"> <a href="https://www.npmjs.com/package/kucoin-api"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://github.com/tiagosiebler/kucoin-api/blob/master/docs/images/logoDarkMode2.svg?raw=true#gh-dark-mode-only"> <img alt="SDK Logo" src="https://github.com/tiagosiebler/kucoin-api/blob/master/docs/images/logoBrightMode2.svg?raw=true#gh-light-mode-only"> </picture> </a> </p> This document provides comprehensive examples for using the KuCoin SPOT API with Node.js and JavaScript.
