ACCOUNT CONNECTION · MT4 & MT5

Connect any MetaTrader account — with one call.

Hand us a login, password and server; get back an account id and a trading key. Then watch its state, reconnect automatically if the broker drops it, and disconnect when you're done — the whole connection lifecycle over the API.

// what it is

The front door to every other endpoint.

The Connection API turns a MetaTrader login into an addressable account you can trade and stream. You POST the login, password and broker server to /ConnectEx; a dedicated terminal boots, logs in, and syncs — and you get back an account id plus a scoped trading key. From then on, every other endpoint targets that account with ?id=. If the broker ever drops the session, /Reconnect rebuilds it, and /ConnectState tells you exactly where a connection stands at any moment.

// the lifecycle

Connect, watch, reconnect, disconnect.

1

Connect

/ConnectEx with login, password and server. Add wait=1 to block until it's live, or use /ConnectStream to watch it come up.

2

Watch

/ConnectState reports one account or all of them; /OnConnectState streams every status change over WebSocket.

3

Recover

/Reconnect rebuilds a dropped session; /Disconnect tears it down cleanly when you're finished.

Frequently asked

How do I connect an MT4 or MT5 account via API?+
Send the login, password and broker server to /ConnectEx. A terminal boots and logs in, and you receive an account id and trading key. Add wait=1 to block until the account is ACTIVE.
What do I do with the account id?+
Every other endpoint — quotes, trading, streaming, EAs — targets the account by passing ?id=. The id is how the API knows which connected terminal to talk to.
What happens if the broker drops the connection?+
Call /Reconnect to rebuild the session, or watch /ConnectState / stream /OnConnectState to detect drops as they happen and react automatically.
Do I pass a server name or a host and port?+
Either. Pass the broker's server name, or a host and port directly. /GetBrokerServersByBrokerName looks up a broker's servers and access points by name.
Does disconnecting stop my billing period?+
/Disconnect removes the live connection but the paid period keeps running; reconnect any time within it without re-provisioning from scratch.
