Ninjatrader

A tiny js wrapper for the NinjaTrader 8 file api.

Read NinjaTrader's documentation for more information about how the file api works.

Getting Started

npm install ninjatrader

or

yarn add ninjatrader

In NinjaTrader, enable automated trading by making sure AT Interface is checked under Tools > Options > Automated Trading Interface.

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 }
});
