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 Scalar Field: your accounts and your data stay with you.

Scalar Field offers an agentic trading desk, and they do it well: agents with their own cash and their own positions, a Python library to program them, and datasets most platforms never offer. It runs in their cloud, at about 300 milliseconds from event to trade. While25 runs on your own computer, connects straight to your accounts and sends orders out in under 0.0005 seconds from signal.

WHILE25SCALAR FIELD
Where it runsA desktop app on your own computer.Their cloud, through a web interface.
SpeedUnder 0.0005 seconds from signal to order. We measure it inside While25 and report the venue's own time separately.About 300 ms from event to trade, by their own figure.
Who sees your dataOnly you. Your orders, positions and broker logins stay on your computer and never pass through our servers.Their platform holds your positions and tracks NAV for you.
Order typesMarket, limit, stop, stop-limit and touched orders, a multi-leg options builder, and fractional quantities.Their agent runtime drives target-based execution.
VenuesInteractive Brokers, Alpaca, Zerodha, Upstox, Symphony XTS.Alpaca, Polymarket, Hyperliquid, Jupiter DEX.
Market dataYou pick the vendor and supply your own credentials.Their bundled datasets, which are deep and well curated.
Strategy isolationEach strategy gets its own money, its own positions and its own stop button. We log every change and never let two strategies trade one symbol.Each agent keeps its own positions, with real-time NAV tracking.
Pre-trade riskWe check every order against your limits: session loss per asset class, order size, number of orders and money in the market. At a loss limit, we stop new orders and close positions.Allocation and target sizing per agent.
ChartingWe build the charts in-house: all the standard indicators plus your custom ones, drawing tools, and orders you place and drag on the chart.Dashboards an agent assembles for you.
What the AI doesIt reads your charts, positions and orders, writes and runs Python, and watches your strategies. You place the orders and start the strategies.Agents deploy and trade on their own once you set them running.
Alternative dataNot our strength today.Prediction markets, on-chain telemetry, point-in-time macro, 13F and Form 4.

WHERE SCALAR FIELD WINS

Data breadthPoint-in-time macro with revision history, historical implied-volatility surfaces, 13F and Form 4 filings. That coverage costs more on its own than their subscription.
Prediction and on-chain venuesPolymarket, Hyperliquid and Jupiter are first-class there. If your edge lives in those markets, that is where to trade it.
Nothing to installA browser and an account and you are running. A desktop app asks more of you on day one.

If your edge lives in prediction markets or on-chain venues, Scalar Field is the better fit. If you trade equities, options, futures or crypto and want charting, execution, risk and Python in one platform on top of the accounts you already hold, While25 fits that.
