Why Siren Exists

The layer between a market idea and a real execution decision.

Know before you click

Siren checks whether the venue can absorb your size before you submit. No more blind clicking on positions that will fail.

Plain English, not error codes

When a route fails, Siren explains exactly why and what to do next. Not a vague venue rejection with no context.

Every trade leaves context

What filled, what failed, what size worked. Siren builds a record after every attempt so you trade smarter next time.

How It Works

Three layers between you and a bad trade.

Siren wraps every prediction market interaction in risk analysis, market intelligence, and execution precision — in that order.

Risk Layer

Understand your exposure before entry

Siren evaluates liquidity depth, slippage risk, and resolution timelines. You see the full picture — not just a price and a buy button.

  • Liquidity depth check
  • Slippage estimation
  • Resolution timeline scoring
Intelligence Layer

Context that sharpens every decision

Every market carries signals — correlated events, volume shifts, and settlement patterns. Siren surfaces them so you act on evidence, not instinct.

  • Cross-market signal detection
  • Volume anomaly alerts
  • Settlement pattern analysis
Execution Layer

Route with precision, not hope

Once you decide, Siren finds the cleanest path to fill. It checks venue capacity, suggests optimal sizing, and logs what happened for your next trade.

  • Smart order routing
  • Position size guidance
  • Full execution audit trail
