While25 is software. It is not a broker, dealer, exchange or investment adviser, and nothing on this site is a recommendation to buy or sell any instrument. Orders you place route to your own brokerage account; While25 never holds funds or securities.

Trading carries risk of loss, including losses greater than your deposit on leveraged products. Backtests and simulations do not predict future returns. Broker and exchange names are trademarks of their owners. We plan to add Coinbase, Binance and Robinhood; you cannot connect them yet.

ABOUT

We're building a platform that works the markets with you.

What it is

While25 is a programmable trading platform with a real Python workspace inside. Your files, a real editor, a real Python process, and the libraries you already use. An indicator you write lands in the chart picker. A dashboard becomes a panel. A strategy trades on your account.

It is a desktop platform for Mac and Windows, and it shows the gist in the browser: market watch, charts, news, fundamentals and AI analysis. While25 Desktop for Mac and Windows is the full product, and it goes out by invite through the waitlist.

The problem we work on is the distance between an idea and a running position. Getting a strategy live normally means building a stack: code, data, broker wiring. Most traders never do that work, so most ideas never trade. While25 removes the stack. The platform is the stack.

Where the assistant fits

The assistant lives inside the workspace. It reads the same charts, panels and files you do. Ask a question and it fetches the data, builds the panel, and writes the report. Bring an idea and it writes the Python into your files: the indicator, the dashboard, the strategy. You read the code and give the yes.

It never decides a trade. Going live takes your confirmation, and once a strategy runs, the orders come from your rules, the same way every time. That keeps it predictable and auditable.

We built the platform from the ground up for people and for agents at the same time. We own every panel, so the assistant can read and operate every surface of the workspace, with money paths as the one deliberate exception.

The engine

Under the workspace sits a C++ engine. We built a real order management system and a chart engine in-house. The engine keeps track of your orders, positions and market data, so every panel and every script works from the same numbers. We route each order to your broker along one predictable path. We connect to Interactive Brokers, Alpaca, Zerodha, Upstox and Symphony XTS today, and if your broker is missing you can request it. We scope the connection with you.

The name

The name is a timestamp from the first build. Build early, put it in traders' hands, and improve in public. We tell you what is stable today and what is still coming.

What's next

Deeper US equity data: fundamentals, company information and live news. Data plugins in the marketplace, so more kinds of data land straight in the workspace. An assistant that can adjust a running strategy, once we can stand behind it. New capabilities ship when they are stable enough to stand behind, and the honest list of what we do not have yet stays on the front page.
