Myriad Order Book

Overview

Use this skill for the full myriad ob ... workflow: discover events and markets, inspect depth, place orders, manage open orders, and manage positions.

Treat the order book as a production BNB Smart Chain workflow by default. Use explicit runtime overrides only when targeting a non-production deployment.

Runtime Sanity

Before execution:

1. Verify the active order book runtime.

• Prefer explicit runtime verification over assumptions.
• Pin --chain-id, API base URL, and contract addresses only when you intentionally need a non-default deployment.

2. Verify signer and balances.

• Confirm the signer exists.
• Confirm native BNB gas is available.
• Confirm USD1 balance is sufficient for buy/split flows.

3. Keep selectors clean.

• Use exactly one of --market-id or --market-slug.
• Use explicit --outcome-id when acting on a specific outcome.
• For event position actions, use exactly one of --event or --neg-risk-id and set --outcome-index.

Recommended Workflow

1. Discover markets.

• Start with myriad ob events list for grouped multi-outcome events.
• Use myriad ob events show to inspect sibling markets before trading an event outcome.
• Start with myriad ob markets list.
• Use myriad ob markets show for final market inspection.

2. Inspect liquidity before writing.

• Use myriad ob events orderbook --render for NegRisk event-level depth.
• Use myriad ob events actions for event-level taker trade history.
• Use myriad ob markets orderbook for current depth.
• Use myriad ob markets orderbook --render for a terminal ladder view.
• Use myriad ob markets trades to inspect recent prints and last-price context.

3. Dry-run writes first.

• Use --dry-run before any order or position write.

4. Manage the lifecycle after submit.

• Use myriad ob orders list/show to inspect status.
• Use myriad ob orders cancel for single orders.
• Use myriad ob orders cancel batch <hash...> for selected-order cleanup.
• Use myriad ob orders cancel market --market-id|--market-slug for explicit market-scoped cleanup.
• Use myriad ob orders cancel all for all-markets cleanup, or keep myriad ob orders cancel all --market-id|--market-slug for compatibility-scoped cleanup.

5. Manage positions explicitly.

• myriad ob positions list for portfolio consultation.
• myriad ob positions split for collateral -> YES + NO.
• myriad ob positions merge for YES + NO -> collateral.
• myriad ob positions neg-risk split and merge for NegRisk event outcome positions.
• myriad ob positions redeem for settled outcomes.

Execution Guidance

• Limit orders: Use explicit --price and --shares; set --time-in-force deliberately and add --expiration when using GTD-style workflows.
• Market orders: Treat --shares as the native exact mode. Treat --value as a best-effort convenience derived from the current book snapshot, not a hard guaranteed spend or proceeds cap.
• Approvals: Buy flows need ERC20 allowance. Sell flows need ERC1155 approval.

Failure Handling

• Wrong chain or deployment: Re-check chain, API base URL, and order book contract settings before retrying.
• Missing signer: Route to /myriad-wallet-ops.
• Missing USD1 or gas: Top up balances before retrying.
• Missing approvals: Re-run with explicit allowance strategy or allow the standard approval flow.
• Insufficient depth: Reduce order size, switch to limit pricing, or wait for the book to refill.
• Selector mismatch: Keep only one of --market-id or --market-slug.
• Event selector mismatch: Keep only one of --event or --neg-risk-id.

Boundaries

• Do not use /myriad-trade-execution for myriad ob ...; this skill owns the order book workflow.
• For wallet/keychain repair, hand off to /myriad-wallet-ops.
• For MCP sequencing details, hand off to /myriad-mcp-orchestration.
