overview: >-
  Paper-trade against the live order book without risking real money. Sandbox
  uses the same SOR, the same venue edges, and the same fill router as
  production. Live and sandbox run inside the same edge processes; per-order
  dispatch is decided by the is_sandbox flag.
test_vs_live:
  key_prefixes:
    live: seq_live_
    test: seq_test_
  enable:
  - method: sandbox key (recommended)
    detail: A seq_test_ key forces every order through sandbox.
  - method: per-order flag
    detail: Set sandbox:true on individual order bodies when using a live key.

  effect: >-
    Wipes all sandbox positions (positions_v2 rows with is_sandbox=true), clears
    the SOR in-memory paper balance cache, and re-seeds default balances
    ($1B per quote asset across all venues including Kalshi, Polymarket, DEX).
  customize_balances: PUT /v1/sandbox/settings (call first to customize defaults)
seed_positions: POST /v1/sandbox/positions
cli:
  flag: --sandbox
  note: Or login with seq_test_ credentials; fills settle against live NBBO with realistic slippage.
