We run all of our technology in-house.
Everything from our website to the client hub (with exclusive features like Fusion+, trading calculators) are proprietary to us. We spend a lot of time and resources (tech and development is our biggest expense) thinking about how we can make our client's trading experience better than anything else they've had before. While we use a "bridge" to go from MT4 to the underlying FX market, generally we prefer to offer as much as we can in-house, and always will be.
We couldn't achieve that mission if we relied on a third party or a white label for our technology. That would make us like everyone else in the market, which isn't what our mission is about.
