CopyFactory trade copying API for javascript (a member of metaapi.cloud project)

CopyFactory is a powerful copy trading API which makes developing forex trade copying applications as easy as writing few lines of code.

CopyFactory API is a member of MetaApi project (https://metaapi.cloud), a powerful cloud forex trading API which supports both MetaTrader 4 and MetaTrader 5 platforms.

MetaApi is a paid service, however we offer a free tier for testing and personal use.

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.

Why do we offer CopyFactory trade copying API

We found that developing reliable and flexible trade copier is a task which requires lots of effort, because developers have to solve a series of complex technical tasks to create a product.

We decided to share our product as it allows developers to start with a powerful solution in almost no time, saving on development and infrastructure maintenance costs.

Retrieving API token

Please visit https://app.metaapi.cloud/token web UI to obtain your API token.

Configuring trade copying

In order to configure trade copying you need to:

• add MetaApi MetaTrader accounts with CopyFactory as application field value (see above)
• create CopyFactory master and slave accounts and connect them to MetaApi accounts via connectionId field
• create a strategy being copied
• subscribe slave CopyFactory accounts to the strategy

import MetaApi, {CopyFactory} from 'metaapi.cloud-sdk';

const token = '...';
const metaapi = new MetaApi(token);
const copyfactory = new CopyFactory(token);

// retrieve MetaApi MetaTrader accounts with CopyFactory as application field value
// master account must have PROVIDER value in copyFactoryRoles
const masterMetaapiAccount = await api.metatraderAccountApi.getAccount('masterMetaapiAccountId');
if(!masterMetaapiAccount.copyFactoryRoles || !masterMetaapiAccount.copyFactoryRoles.includes('PROVIDER')) {
  throw new Error('Please specify PROVIDER copyFactoryRoles value in your MetaApi account in ' +
    'order to use it in CopyFactory API');
}
// slave account must have SUBSCRIBER value in copyFactoryRoles
const slaveMetaapiAccount = await api.metatraderAccountApi.getAccount('slaveMetaapiAccountId');
if(!slaveMetaapiAccount.copyFactoryRoles || !slaveMetaapiAccount.copyFactoryRoles.includes('SUBSCRIBER')) {
  throw new Error('Please specify SUBSCRIBER copyFactoryRoles value in your MetaApi account in ' +
    'order to use it in CopyFactory API');
}

let configurationApi = copyfactory.configurationApi;

// create a strategy being copied
let strategyId = await configurationApi.generateStrategyId();
await configurationApi.updateStrategy(strategyId.id, {
  name: 'Test strategy',
  description: 'Some useful description about your strategy',
  accountId: masterMetaapiAccount.id,
  maxTradeRisk: 0.1,
  timeSettings: {
    lifetimeInHours: 192,
    openingIntervalInMinutes: 5
  }
});

// subscribe slave CopyFactory accounts to the strategy
await configurationApi.updateSubscriber(slaveMetaapiAccount.id, {
  name: 'Demo account',
  subscriptions: [
    {
      strategyId: strategyId.id,
      multiplier: 1
    }
  ]
});

See esdoc in-code documentation for full definition of possible configuration options.

Retrieving paginated lists

There are two groups of methods to retrieve paginated lists:

• with pagination in infinite scroll style
• with pagination in a classic style which allows you to calculate page count

They are applied to following entities:

• strategies: getStrategiesWithInfiniteScrollPagination and getStrategiesWithClassicPagination
• provider portfolios: getPortfolioStrategiesWithInfiniteScrollPagination and getPortfolioStrategiesWithClassicPagination
• subscribers: getSubscribersWithInfiniteScrollPagination and getSubscribersWithClassicPagination

Example of retrieving strategies with pagination in infinite scroll style:

// paginate strategies, see esdoc for full list of filter options available
const strategies = await api.metatraderAccountApi.getStrategiesWithInfiniteScrollPagination({limit: 10, offset: 0});

// get strategies without filter (returns 1000 strategies max)
const strategies = await api.metatraderAccountApi.getStrategiesWithInfiniteScrollPagination();
const strategy = strategies.find(strategy => strategy._id === 'strategyId');

Example of retrieving strategies with paginiation in classic style:

// paginate strategies, see esdoc for full list of filter options available
const strategies = await api.metatraderAccountApi.getStrategiesWithClassicPagination({limit: 10, offset: 0});
const strategy = strategies.items.find(strategy => strategy._id === 'strategyId');
// number of all strategies matching filter without pagination options
console.log(strategies.count);

// get strategies without filter (returns 1000 strategies max)
const strategies = await api.metatraderAccountApi.getStrategiesWithClassicPagination();

Retrieving trade copying history

CopyFactory allows you to monitor transactions conducted on trading accounts in real time.

Retrieving trading history on provider side

let historyApi = copyfactory.historyApi;

// retrieve trading history, please note that this method support pagination and limits number of records
console.log(await historyApi.getProvidedTransactions(new Date('2020-08-01'), new Date('2020-09-01')));

Retrieving trading history on subscriber side

let historyApi = copyfactory.historyApi;

// retrieve trading history, please note that this method support pagination and limits number of records
console.log(await historyApi.getSubscriptionTransactions(new Date('2020-08-01'), new Date('2020-09-01')));

Resynchronizing slave accounts to masters

There is a configurable time limit during which the trades can be opened. Sometimes trades can not open in time due to broker errors or trading session time discrepancy. You can resynchronize a slave account to place such late trades. Please note that positions which were closed manually on a slave account will also be reopened during resynchronization.

let accountId = '...'; // CopyFactory account id

// resynchronize all strategies
await copyfactory.tradingApi.resynchronize(accountId);

// resynchronize specific strategy
await copyfactory.tradingApi.resynchronize(accountId, ['ABCD']);

Sending external trading signals to a strategy

You can submit external trading signals to your trading strategy.

const accountId = '...';
const tradingApi = copyfactory.tradingApi;
const signalId = '...';

// get signal client
const strategySignalClient = await tradingApi.getStrategySignalClient(strategyId);

// add trading signal
await strategySignalClient.updateExternalSignal(signalId, {
  symbol: 'EURUSD',
  type: 'POSITION_TYPE_BUY',
  time: new Date(),
  volume: 0.01
});

// get external signals
console.log(await signalClient.getStrategyExternalSignals(strategyId));

// remove signal
await strategySignalClient.removeExternalSignal(signalId, {
  time: new Date()
});

Retrieving trading signals

const accountId = '...';
const subscriberSignalClient = await tradingApi.getSubscriberSignalClient(accountId);

// retrieve trading signals
console.log(await subscriberSignalClient.getTradingSignals());

Managing stopouts

A subscription to a strategy can be stopped if the strategy have exceeded allowed risk limit.

let tradingApi = copyfactory.tradingApi;
let accountId = '...'; // CopyFactory account id
let strategyId = '...'; // CopyFactory strategy id

// retrieve list of strategy stopouts
console.log(await tradingApi.getStopouts(accountId));

// reset a stopout so that subscription can continue
await tradingApi.resetSubscriptionStopouts(accountId, strategyId, 'daily-equity');

Managing stopout listeners

You can subscribe to a stream of stopout events using the stopout listener.

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

let tradingApi = copyfactory.tradingApi;

// create a custom class based on the StopoutListener
class Listener extends StopoutListener {

  // specify the function called on event arrival
  async onStopout(strategyStopoutEvent) {
    console.log('Strategy stopout event', strategyStopoutEvent);
  }

  // specify the function called on error event
  async onError(error) {
    console.log('Error event', error);
  }

}

// add listener
const listener = new Listener();
const listenerId = tradingApi.addStopoutListener(listener);

// remove listener
tradingApi.removeStopoutListener(listenerId);

Retrieving slave trading logs

let tradingApi = copyfactory.tradingApi;
let accountId = '...'; // CopyFactory account id

// retrieve slave trading log
console.log(await tradingApi.getUserLog(accountId));

// retrieve paginated slave trading log by time range
console.log(await tradingApi.getUserLog(accountId, new Date(Date.now() - 24 * 60 * 60 * 1000), undefined, 20, 10));

Log streaming

You can subscribe to a stream of strategy or subscriber log events using the user log listener.

Strategy logs

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

let tradingApi = copyfactory.tradingApi;

// create a custom class based on the UserLogListener
class Listener extends UserLogListener {

  // specify the function called on event arrival
  async onUserLog(logEvent) {
    console.log('Strategy user log event', logEvent);
  }

  // specify the function called on error event
  async onError(error) {
    console.log('Error event', error);
  }

}

// add listener
const listener = new Listener();
const listenerId = tradingApi.addStrategyLogListener(listener, 'ABCD');

// remove listener
tradingApi.removeStrategyLogListener(listenerId);

Subscriber logs

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

let tradingApi = copyfactory.tradingApi;

// create a custom class based on the UserLogListener
class Listener extends UserLogListener {

  // specify the function called on event arrival
  async onUserLog(logEvent) {
    console.log('Subscriber user log event', logEvent);
  }

  // specify the function called on error event
  async onError(error) {
    console.log('Error event', error);
  }

}

// add listener
const listener = new Listener();
const listenerId = tradingApi.addSubscriberLogListener(listener, 'accountId');

// remove listener
tradingApi.removeSubscriberLogListener(listenerId);

Transaction streaming

You can subscribe to a stream of strategy or subscriber transaction events using the transaction listener.

Strategy transactions

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

let historyApi = copyfactory.historyApi;

// create a custom class based on the TransactionListener
class Listener extends TransactionListener {

  // specify the function called on event arrival
  async onTransaction(transactionEvent) {
    console.log('Strategy transaction event', transactionEvent);
  }

  // specify the function called on error event
  async onError(error) {
    console.log('Error event', error);
  }

}

// add listener
const listener = new Listener();
const listenerId = historyApi.addStrategyTransactionListener(listener, 'ABCD');

// remove listener
historyApi.removeStrategyTransactionListener(listenerId);

Subscriber transactions

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

let historyApi = copyfactory.historyApi;

// create a custom class based on the TransactionListener
class Listener extends TransactionListener {

  // specify the function called on event arrival
  async onTransaction(transactionEvent) {
    console.log('Subscriber transaction event', transactionEvent);
  }

  // specify the function called on error event
  async onError(error) {
    console.log('Error event', error);
  }

}
