To run our tools and use NinjaTrader, you need a data feed.

If you have a funded broker account, your broker can provide the data you need. Contact them about the data feeds they offer. There will likely be some cost, but many brokerages waive the fees after you have made a sufficient number of trades.

If you are not ready to fund a broker account, you can get market data from various sources for a monthly fee that varies based on which markets you require data from.

One of the services we have used and is recommended by NinjaTrader is Kinetic.com. They provide live and historical data for NinjaTrader.
