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.

COMPARISON

While25 vs QuantConnect: a platform, not a notebook.

QuantConnect deserves the respect of anyone who writes trading code: LEAN is a real engine, and Python is a first-class citizen there. The difference is category. QuantConnect is a cloud research platform you visit to build algorithms. While25 is the platform you sit in all day, charts, orders, options, watchlists, with the Python workspace living beside them.

WHILE25QUANTCONNECT
CategoryA programmable trading platform with a Python development environment inside.A cloud research and backtesting platform for algorithms.
Where code runsA Python 3.12 process on your machine, beside your charts and orders.Their cloud, or a self-hosted LEAN engine you operate.
Discretionary tradingThe full platform: charts, DOM, option chain, order ticket, trade by hand or by code.Not the product; algorithms are the product.
Your filesA local workspace: drag in CSV, Excel, Parquet or PDF and read them from scripts.Project files in their cloud environment.
DashboardsPanels you code in Python, living in the platform you trade from.Research notebooks and backtest reports.
Indicators on chartsYour custom indicator shows up in the chart's indicator list next to the built-in ones.Indicators serve algorithms, not a charting workspace.
BrokersIBKR, Alpaca, Zerodha, Upstox, or request yours.A solid list of live-trading brokerages for deployed algorithms.
AIAn agent in the workspace that writes code you approve.AI research tooling around their data and docs.

WHERE QUANTCONNECT WINS

Backtesting infrastructureInstitutional-grade cloud backtesting over deep historical data is the core product, and it shows.
Data libraryA large curated data catalog attached to the research environment.
Open sourceLEAN is open source with a serious engineering community.

If your work is pure systematic research, QuantConnect is a fine laboratory. If you actually trade, watching charts, working orders, running an option book, and want your Python living in that same room, that is what While25 is.
