Package Exports

metaapi.cloud-sdk

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (metaapi.cloud-sdk) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

metaapi.cloud SDK for node.js

MetaApi is a powerful, fast, cost-efficient, easy to use and standards-driven cloud forex trading API for MetaTrader 4 and MetaTrader 5 platform designed for traders, investors and forex application developers to boost forex application development process. MetaApi can be used with any broker and does not require you to be a brokerage.

MetaApi is a paid service, but API access to one MetaTrader account is free of charge.

The MetaApi pricing was developed with the intent to make your charges less or equal to what you would have to pay for hosting your own infrastructure. This is possible because over time we managed to heavily optimize our MetaTrader infrastructure. And with MetaApi you can save significantly on application development and maintenance costs and time thanks to high-quality API, open-source SDKs and convenience of a cloud service.

Official REST and websocket API documentation: https://metaapi.cloud/docs/client/

Please note that this SDK provides an abstraction over REST and websocket API to simplify your application logic.

For more information about SDK APIs please check esdoc documentation in source codes located inside lib folder of this npm package.

Installation

npm install --save metaapi.cloud-sdk

Installing SDK in browser SPA applications

npm install --save metaapi.cloud-sdk

Installing SDK in browser HTML applications

<script src="unpkg.com/metaapi.cloud-sdk/index.js"></script>
<script>
    const token = '...';
    const api = new MetaApi(token);
</script>

Working code examples

You can find code examples at examples folder of our github repo or in the examples folder of the npm package.

We have composed a short guide explaining how to use the example code

Connecting to MetaApi

Please use one of these ways:

https://app.metaapi.cloud/token web UI to obtain your API token.
An account access token which grants access to a single account. See section below on instructions on how to retrieve account access token.

Supply token to the MetaApi class constructor.

import MetaApi from 'metaapi.cloud-sdk';

const token = '...';
const api = new MetaApi(token);

Retrieving account access token

Account access token grants access to a single account. You can retrieve account access token via API:

let accountId = '...';
let account = await api.metatraderAccountApi.getAccount(accountId);
let accountAccessToken = account.accessToken;
console.log(accountAccessToken);

Alternatively, you can retrieve account access token via web UI on https://app.metaapi.cloud/accounts page (see this video).

Managing MetaTrader accounts (API servers for MT accounts)

Before you can use the API you have to add an MT account to MetaApi and start an API server for it.

However, before you can create an account, you have to create a provisioning profile.

Managing provisioning profiles via web UI

You can manage provisioning profiles here: https://app.metaapi.cloud/provisioning-profiles

Creating a provisioning profile via API

// if you do not have created a provisioning profile for your broker,
// you should do it before creating an account
const provisioningProfile = await api.provisioningProfileApi.createProvisioningProfile({
  name: 'My profile',
  version: 5
});
// servers.dat file is required for MT5 profile and can be found inside
// config directory of your MetaTrader terminal data folder. It contains
// information about available broker servers
await provisioningProfile.uploadFile('servers.dat', '/path/to/servers.dat');
// for MT4, you should upload an .srv file instead
await provisioningProfile.uploadFile('broker.srv', '/path/to/broker.srv');

Retrieving existing provisioning profiles via API

const provisioningProfiles = await api.provisioningProfileApi.getProvisioningProfiles();
const provisioningProfile = await api.provisioningProfileApi.getProvisioningProfile('profileId');

Updating a provisioning profile via API

await provisioningProfile.update({name: 'New name'});
// for MT5, you should upload a servers.dat file
await provisioningProfile.uploadFile('servers.dat', '/path/to/servers.dat');
// for MT4, you should upload an .srv file instead
await provisioningProfile.uploadFile('broker.srv', '/path/to/broker.srv');

Removing a provisioning profile

await provisioningProfile.remove();

Managing MetaTrader accounts (API servers) via web UI

You can manage MetaTrader accounts here: https://app.metaapi.cloud/accounts

Create a MetaTrader account (API server) via API

const account = await api.metatraderAccountApi.createAccount({
  name: 'Trading account #1',
  type: 'cloud',
  login: '1234567',
  // password can be investor password for read-only access
  password: 'qwerty',
  server: 'ICMarketsSC-Demo',
  // synchronizationMode can be 'automatic' for RPC access or 'user' if you
  // want to keep track of terminal state in real-time (e.g. if you are
  // developing a EA or trading strategy)
  synchronizationMode: 'automatic',
  provisioningProfileId: provisioningProfile.id,
  //algorithm used to parse your broker timezone. Supported values are
  // icmarkets for America/New_York DST switch and roboforex for EET
  // DST switch (the values will be changed soon)
  timeConverter: 'roboforex',
  application: 'MetaApi',
  magic: 123456
});

Retrieving existing accounts via API

// filter and paginate accounts, see esdoc for full list of filter options available
const accounts = await api.metatraderAccountApi.getAccounts({
  limit: 10,
  offset: 0,
  query: 'ICMarketsSC-MT5',
  state: ['DEPLOYED']
});
// get accounts without filter (returns 1000 accounts max)
const accounts = await api.metatraderAccountApi.getAccounts();

const account = await api.metatraderAccountApi.getAccount('accountId');

Updating an existing account via API

await account.update({
  name: 'Trading account #1',
  login: '1234567',
  // password can be investor password for read-only access
  password: 'qwerty',
  server: 'ICMarketsSC-Demo',
  // synchronizationMode can be 'automatic' for RPC access or 'user' if you
  // want to keep track of terminal state in real-time (e.g. if you are
  // developing a EA or trading strategy)
  synchronizationMode: 'automatic'
});

Removing an account

await account.remove();

Deploying, undeploying and redeploying an account (API server) via API

await account.deploy();
await account.undeploy();
await account.redeploy();

Access MetaTrader account via RPC API

RPC API let you query the trading terminal state. You should use RPC API if you develop trading monitoring apps like myfxbook or other simple trading apps.

You should create your account with automatic synchronization mode if all you need is RPC API.

Query account information, positions, orders and history via RPC API

const connection = await account.connect();

await connection.waitSynchronized();

// retrieve balance and equity
console.log(await connection.getAccountInformation());
// retrieve open positions
console.log(await connection.getPositions());
// retrieve a position by id
console.log(await connection.getPosition('1234567'));
// retrieve pending orders
console.log(await connection.getOrders());
// retrieve a pending order by id
console.log(await connection.getOrder('1234567'));
// retrieve history orders by ticket
console.log(await connection.getHistoryOrdersByTicket('1234567'));
// retrieve history orders by position id
console.log(await connection.getHistoryOrdersByPosition('1234567'));
// retrieve history orders by time range
console.log(await connection.getHistoryOrdersByTimeRange(startTime, endTime));
// retrieve history deals by ticket
console.log(await connection.getDealsByTicket('1234567'));
// retrieve history deals by position id
console.log(await connection.getDealsByPosition('1234567'));
// retrieve history deals by time range
console.log(await connection.getDealsByTimeRange(startTime, endTime));

Query contract specifications and quotes via RPC API

const connection = await account.connect();

await connection.waitSynchronized();

// first, subscribe to market data
await connection.subscribeToMarketData('GBPUSD');

// read constract specification
console.log(await connection.getSymbolSpecification('GBPUSD'));
// read current price
console.log(await connection.getSymbolPrice('GBPUSD'));

Use real-time streaming API

Real-time streaming API is good for developing trading applications like trade copiers or automated trading strategies. The API synchronizes the terminal state locally so that you can query local copy of the terminal state really fast.

In order to use this API you need to create an account with user synchronization mode.

Synchronizing and reading teminal state

const account = await api.metatraderAccountApi.getAccount('accountId');

// account.synchronizationMode must be equal to 'user' at this point

// access local copy of terminal state
const terminalState = connection.terminalState;

// wait until synchronization completed
await connection.waitSynchronized();

console.log(terminalState.connected);
console.log(terminalState.connectedToBroker);
console.log(terminalState.accountInformation);
console.log(terminalState.positions);
console.log(terminalState.orders);
// symbol specifications
console.log(terminalState.specifications);
console.log(terminalState.specification('EURUSD'));
console.log(terminalState.price('EURUSD'));

// access history storage
historyStorage = connection.historyStorage;

// both orderSynchronizationFinished and dealSynchronizationFinished
// should be true once history synchronization have finished
console.log(historyStorage.orderSynchronizationFinished);
console.log(historyStorage.dealSynchronizationFinished);

Overriding local history storage

By default history is stored in memory only. You can override history storage to save trade history to a persistent storage like MongoDB database.

import {HistoryStorage} from 'metaapi.cloud-sdk';

class MongodbHistoryStorage extends HistoryStorage {
  // implement the abstract methods, see MemoryHistoryStorage for sample
  // implementation
}

let historyStorage = new MongodbHistoryStorage();

// Note: if you will not specify history storage, then in-memory storage
// will be used (instance of MemoryHistoryStorage)
const connection = await account.connect(historyStorage);

// access history storage
historyStorage = connection.historyStorage;

// invoke other methods provided by your history storage implementation
console.log(await historyStorage.yourMethod());

Receiving synchronization events

You can override SynchronizationListener in order to receive synchronization event notifications, such as account/position/order/history updates or symbol quote updates.

import {SynchronizationListener} from 'metaapi.cloud-sdk';

// receive synchronization event notifications
// first, implement your listener
class MySynchronizationListener extends SynchronizationListener {
  // override abstract methods you want to receive notifications for
}

// now add the listener
const listener = new MySynchronizationListener();
connection.addSynchronizationListener(listener);

// remove the listener when no longer needed
connection.removeSynchronizationListener(listener);

Retrieve contract specifications and quotes via streaming API

const connection = await account.connect();

await connection.waitSynchronized();

// first, subscribe to market data
await connection.subscribeToMarketData('GBPUSD');

// read constract specification
console.log(terminalState.specification('EURUSD'));
// read current price
console.log(terminalState.price('EURUSD'));

Execute trades (both RPC and streaming APIs)

const connection = await account.connect();

await connection.waitSynchronized();

// trade
console.log(await connection.createMarketBuyOrder('GBPUSD', 0.07, 0.9, 2.0, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAl'}));
console.log(await connection.createMarketSellOrder('GBPUSD', 0.07, 2.0, 0.9, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAl'}));
console.log(await connection.createLimitBuyOrder('GBPUSD', 0.07, 1.0, 0.9, 2.0, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAl'}));
console.log(await connection.createLimitSellOrder('GBPUSD', 0.07, 1.5, 2.0, 0.9, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAl'}));
console.log(await connection.createStopBuyOrder('GBPUSD', 0.07, 1.5, 0.9, 2.0, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAl'}));
console.log(await connection.createStopSellOrder('GBPUSD', 0.07, 1.0, 2.0, 0.9, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAl'}));
console.log(await connection.modifyPosition('46870472', 2.0, 0.9));
console.log(await connection.closePositionPartially('46870472', 0.9));
console.log(await connection.closePosition('46870472'));
console.log(await connection.closePositionsBySymbol('EURUSD'));
console.log(await connection.modifyOrder('46870472', 1.0, 2.0, 0.9));
console.log(await connection.cancelOrder('46870472'));

// if you need to, check the extra result information in stringCode and numericCode properties of the response
const result = await connection.createMarketBuyOrder('GBPUSD', 0.07, 0.9, 2.0, {comment: 'comment', clientId: 'TE_GBPUSD_7hyINWqAlE'});
console.log('Trade successful, result code is ' + result.stringCode);
