Example

Initialize

import NinjaTrader from 'ninjatrader';

const nt = new NinjaTrader({
    account: "Sim101"
});

Place a market order

import { NinjaTraderAction, NinjaTraderTif, OrderStatus } from 'ninjatrader';

const order = await nt.market({
    action: NinjaTraderAction.Buy,
    quantity: 69,
    tif: NinjaTraderTif.Day,
    instrument: "AMC",
    onUpdate: (status: OrderStatus, state: OrderState) => {
        switch(status) {
            case OrderStatus.Rejected:
                // order rejected
                break;
            case OrderStatus.Filled:
                // order filled
                console.log(state); // { quantity: 69, price: 49.40 }
                break;
        }
    },
    onRejected: (state: OrderState) => {
        // order rejected
        console.log(state); // { quantity: 0, price: 0 }
    }
}); // order accepted after await

Place a limit order with a stop loss

import { NinjaTraderAction, NinjaTraderTif } from 'ninjatrader';

const order = await nt.limit({
    action: NinjaTraderAction.Buy,
    quantity: 69,
    tif: NinjaTraderTif.Day,
    instrument: "GME",
    limitPrice: 1000,
    stopPrice: 980
});

console.log(order); // { quantity: 69, price: 998.12 }

Cancel an order

import { NinjaTraderAction, NinjaTraderTif } from 'ninjatrader';

const orderId = "1"; // random unique id

nt.market({
    action: NinjaTraderAction.Buy,
    quantity: 69,
    tif: NinjaTraderTif.Day,
    instrument: "BTCUSD",
    orderId
});

nt.cancel({
    orderId
});

Update an order

import { NinjaTraderAction, NinjaTraderTif } from 'ninjatrader';

const orderId = "1"; // random unique id

nt.limit({
    action: NinjaTraderAction.Buy,
    quantity: 69,
    tif: NinjaTraderTif.Day,
    limitPrice: 17.21,
    stopPrice: 17.15,
    instrument: "BB",
    orderId
});

nt.change({
    quantity: 69,
    stopPrice: 17.19,
    orderId
});

Listen for connection status

nt.onConnected("Simulated Data Feed", () => {
    // simulated data feed connected
});

nt.onDisconnected("Simulated Data Feed", () => {
    // simulated data feed disconnected
});

nt.onConnection("Simulated Data Feed", (connected: boolean) => {
    console.log(connected); // true / false
})

Listen for position changes

nt.onPosition("ETHUSD", (position: PositionUpdateState) => {
    console.log(position); // { position: 'LONG', quantity: 4, price: 2336.46 }
});
