Yes you can. You can use any datafeed that is compatible with NinjaTrader. But be thoughtful about using something different.
We recommend using the datafeed recommended by TradePro, our favorite broker. Using this datafeed will help you in several ways,.one being that it’s good clean market data, and the other that it’s been well tested.
We know that sometimes the "lag" of the any feed differing from your actual broker prices can be a bit confusing, but we promise…it IS something that you will grow accustomed to, and eventually even like it.
If you use your own datafeed from your own broker for example, the characteristics and display of the indicators may change significantly, depending on how price is reflected in that feed.
For example, let’s say you have an Interactive Brokers live account and want to use that feed. You can do that easily with NinjaTrader as that is one of their "trading partners". So, the good news is you could have your NinjaTrader Chart showing your actual Broker quotes, and could even trade "live on the chart" with NinjaTrader. But, the challenge is…the datafeed is a little different…meaning the quotes are sent to the chart in a different style…even faster…and it will change the appearance of the charts.
Of course, if you choose to do this…it IS something you can actually prefer…just remember that you will need to spend some time "training your brain" to see and recognize the differences between what a "regular Logical Forex recommended datafeed" chart looks like, and your other datafeed looks like. After you’ve done that "brain training", you’ll be fine.
You can also use other available adapters to bridge, for example, some Currenex Brokers, to the NinjaTrader Platform.
But, for the most part, we recommend that you use the datafeed recommended by TradePro. Not only is it a reliable datafeed, I use it, and have for a long time. Plus, that is the datafeed we use when we post charts on the blog and elsewhere, so "your charts and mine" will always look the same… making it easier for you to "see what I see".
