Real-time market analytics, built on our own data feed.
Sentinelle captures live futures and options data for S&P 500 instruments, processes it server-side, and turns it into key price levels and signals that traders can read directly on the chart.
What Sentinelle does
One platform that goes from raw market data to a chart a trader can act on, without depending on third-party analytics.
Live data capture
Continuous ingestion of real-time futures and options market data for S&P 500 instruments, including ES, SPX and SPY.
Server-side analytics
Data is stored, aggregated into candles and analysed on the server on a short, fixed processing cycle.
Key price levels
The platform derives price levels of interest from options activity and market structure, and tracks how price reacts to them.
Chart-first delivery
Levels and signals are displayed as overlays on live price charts, so the analysis is read where trading decisions are made.
How it works
Sentinelle runs on its own data feed, from the exchange data subscription to the browser.
Market data in
Licensed real-time feeds are captured by dedicated services and written to the database as they arrive.
Aggregate and compute
SQL Server aggregates ticks into multi-timeframe candles and computes levels and signals through stored procedures.
Datafeed API
An ASP.NET Core backend exposes history over REST and live updates over WebSocket to the web client.
Interactive charts
The web client renders live candles together with Sentinelle's computed levels and signal annotations.
Project status
