We maintain our own data feed directly and do not rely on third party connections or providers. This allows us to provide our traders data sourced directly from the exchange(s), unfiltered. ### Required Agreements Upon your first time logging into the platform, you will be required to complete various market data entitlement and platform usage agreements. These include our CME ILA agreement, Non-Pro / Pro self certification, and our market data terms of use. ### Data Centers The TopstepX primary market data servers are located in Northern Virginia. All traders, regardless of their geographic location, will connect to this region for market data.\ \ TopstepX uses advanced cloud computing technology, including the Amazon AWS global accelerator private backhaul, for connections to these data centers from cloud computing edge locations across the globe. Regardless of this technology, any disruption between the trader's PC and our market data servers are out of our control. Traders are encourage to have the most reliable, hard wired connection possible when using our services. ### Performance In order to provide the best experience for active professional level day traders, TopstepX is a compute and render intensive web application requiring a moderate to high end machine and fast, reliable data connection. Our data updates at a refresh interval of 50ms on the 'fast', compared to some web based charting / trading platforms who update at 750ms or greater. This can cause issues on slow or under performant machines or for traders located at far distances geographically from our data plants located in Northern Virginia, USA. If you are experiencing slowness, or chat lag, please take these basic troubleshooting steps:\ \ \- Ensure you are hardwired to a reliable internet connection. Use a website to check your connection quality (not speed test) to USA based servers.\ \- Lower your market data refresh rate to 'Slow'.\ \- Switch to a single chart, with no indicators; only adding indicators and charts if no issues. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://help.topstepx.com/getting-started/data-feed.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
