All-in-one
basket
engine.
A fast and modular index engine
for the news.
All-in-one
The complete
Broker's toolbox
Break free from single-name instruments and launch a whole story as one index, with a single API.
01 · Basket
Basket intelligence
Point it at a story. Get the constituents, a direction and a weight for every leg.
02 · Index
Index and marks
Every basket becomes one published level. It starts at 1,000, and it is spread-free.
03 · Live marks
Live mark stream
Subscribe once and marks arrive as they move. No polling, no stale screens.
04 · Licence
Configured to your licence
Five configurations, from basket ideas only to the whole stack. Your profile decides which modules turn on.
05 · Trade
Intuitive API
Quote, trade and close on one REST surface. Preview writes nothing; commit opens the contract.
06 · Netting
Exposure and netting
Report order intent. Cascade splits it into signed legs, nets the book, and emits the hedge delta.
07 · Risk
Advisory risk signals
Valuation, margin and loss-cut signals from marks and positions. Cascade computes; the Broker acts.
08 · Ops
Runs like
Runs like
clockwork
Idempotent order intent, signed webhooks, a full audit log, and controls that fail closed.
A separable
and modular engine
Keep your stack small by only taking the modules you need.
Where Cascade runs
Customer money stays with the Broker. Cascade sits behind the product as the compute layer.
