Connect Meta Trader 4 with NestJS Socket Gateway trough ZeroMQ

Before to start

Before to start the project, the Meta Trader 4 terminal must be started with MetaTrader4Bridge2.mq4 activated. More about that MQL 4 Folder for ZeroMQ for Meta Trader 4

Example usage

ZeroMQ ports and password can be changed - meta-trader.service.ts

import { MetaTrader4 } from './MetaTrader4';

@Injectable()
export class MetaTraderService {
    MetaTrader = new MetaTrader4({
        apiKey: 'CHANGEME',
        reqUrl: 'tcp://127.0.0.1:5555',
        pullUrl: 'tcp://127.0.0.1:5556',
    });
}

WS Socket is started on port 8888 - socket.gateway.ts

@WebSocketGateway(8888)
export class SocketGateway implements OnGatewayInit {
    @WebSocketServer()
    server: Server;
    subscription: Subscription;
    currentRates: any;

    constructor(private mtService: MetaTraderService) {
        this.mtService.connect();
    }
}

To connect meta-trader.service.ts with Meta Trader 4 trough ZeroMQ is used the Peter Szombati project
