TRADE BUILDER

Build Complex Trades Through Conversation

Natural language in, structured multi-leg positions out. Preview before you commit.

Describe It. Preview It. Execute It.

Walk through a real conversation that constructs a multi-leg conditional trade.

Trade Builder
YOU
I want to bet on the Fed cutting rates in March. But I also want a hedge -- if they hold, I want exposure to the "inflation above 3%" contract too.
TB
I can structure that as a two-leg conditional trade. Here is what I am seeing:

Leg 1: BUY YES on "Fed cuts rates in March" -- currently at $0.62
Leg 2: IF Leg 1 loses, BUY YES on "CPI above 3% in Feb" -- currently at $0.44

What position sizes would you like? I can also add stop-losses to either leg.
YOU
Put $100 on the Fed cut and $50 on the inflation hedge. Add a stop-loss on leg 1 if the contract drops below $0.40.
TB
Got it. Here is your structured trade:

Leg 1: BUY 161 YES contracts @ $0.62 ($100)
  Stop-loss: EXIT if price drops below $0.40 (-$35.40 max loss)

Leg 2 (conditional): BUY 113 YES contracts @ $0.44 ($50)
  Triggers only if Leg 1 resolves NO

Max total risk: $135.40 | Max payout: $211
Expected value (based on model): +$18.40

Ready to preview the full execution plan?
YOU
Yes, show me the plan. And what if I wanted to add a third leg on a polymarket contract?
TB
Cross-exchange trades are supported. I can add a Polymarket leg alongside the Kalshi legs. The execution engine handles routing, timing, and settlement differences automatically.

Would you like me to find a correlated contract on Polymarket, or do you have a specific one in mind?

Multi-Leg Positions with Conditions

The Trade Builder does not just place single orders. It constructs structured positions with conditional logic, stop-losses, profit targets, and cross-leg dependencies. Every trade is previewed with a full execution plan before you commit.

Build hedged positions, conditional chains, bracket orders, and portfolio-level trades through natural conversation. The system handles the complexity of multi-contract execution, including timing, routing, and partial fill management.

  • Multi-leg positions with conditional triggers
  • Automatic stop-loss and take-profit levels
  • Expected value calculation on every trade
  • Full preview before any capital is committed

Trade Across Exchanges From One Conversation

The Trade Builder routes orders to the right exchange automatically. Build a position with legs on Kalshi and Polymarket in the same conversation. The execution engine handles differences in settlement, timing, and contract specifications transparently.

Find arbitrage opportunities between exchanges, hedge positions cross-platform, or simply choose the best price across all supported venues. The Trade Builder normalizes contracts so you think in terms of outcomes, not exchange-specific mechanics.

  • Unified order routing across supported exchanges
  • Automatic contract normalization
  • Cross-exchange arbitrage detection
  • Settlement difference handling

Structured trade execution with human approval

Every trade follows a formal lifecycle. Real-time SSE streaming shows each analysis step as it happens — market scan, orderbook depth, risk assessment, cost modeling — before a structured proposal is generated for your review.

STEP 1
PROPOSE
STEP 2
CONFIRM
STEP 3
EXECUTE
STEP 4
COMPLETE

You can modify legs, adjust quantities, or cancel at any point before execution. Every step streams in real-time via SSE — you see tool calls (orderbook analysis, risk check, cost model) execute live in the chat.

Every Trade Structure You Need

From simple single-contract bets to complex conditional chains, the Trade Builder handles it all.

Simple Bets

Single-contract YES/NO positions with optional stop-loss and take-profit levels.

Conditional Chains

If-then logic across multiple contracts. Trigger leg 2 based on leg 1 resolution.

Hedged Positions

Pair correlated contracts to limit downside while maintaining upside exposure.

Bracket Orders

Entry with simultaneous stop-loss and take-profit. Automatic position management.

Cross-Exchange

Multi-leg trades spanning multiple prediction market exchanges. Unified execution.

Portfolio Trades

Rebalance multiple positions at once. Express portfolio-level intent in a single sentence.
