CLI

sequence — the trading OS from your terminal. Every Level 0 → 5 capability in the SDK maps to a subcommand. This page is a reference: every command, every flag, every default, grouped by the product ladder.

Config lives at ~/.sequence/config.toml. Log in once:

sequence login
# paste your seq_live_... (or seq_test_... for sandbox)

Global flags

Every subcommand accepts:

Level 0 — Connect

sequence login

Interactive prompt for your Sequence API key. Writes ~/.sequence/config.toml.

sequence connect <venue>

Store credentials for a venue. Prompts for the fields each venue needs — flat api_key / api_secret for CEX exchanges, an RSA PEM for Kalshi, an EVM signer key for Polymarket.

sequence connect binance
sequence connect okx            # also asks for passphrase
sequence connect kalshi         # asks for key ID + pastes RSA PEM
sequence connect polymarket     # asks for signer private key (+ optional proxy / builder)

Supported venues: binance, coinbase, kraken, okx, bybit, kalshi, polymarket, hyperliquid, bitget, cryptocom, dex_ethereum, solana.

sequence disconnect <venue>

Delete stored credentials. Rotate before the session that uses the new key — edges cache credentials until reconnect.

sequence venues

List every connected venue with heartbeat state.

Level 1 — See

sequence quote <symbol>

Real-time NBBO + per-venue BBO.

NBBO         BID          ASK      SPREAD
best     2,325.53     2,325.54    0.00 bps

VENUE         BID          ASK    BID_SZ    ASK_SZ    AGE
binance   2,325.53     2,325.54     12.4       8.1    42ms
coinbase  2,325.48     2,325.60      0.8       1.2    55ms

Works with CEX pairs, Polymarket slugs, Kalshi tickers, and raw token IDs.

sequence positions [flags]

Unified view of everything you hold — fiat cash, crypto, perps, and event contracts — across every venue in one table. Replaces the removed sequence balances command.

sequence symbols

Every tradable instrument. Filter with grep or pipe through jq if you've set --output json in a future invocation.

sequence fees <ticker> [--venues kalshi,polymarket]

Maker/taker fees per venue for one ticker. Renders a small table; — means the venue has no fee data yet (treat as do-not-route, not free).

sequence fees BTC-USD
sequence fees KXMLBHR-26APR292140KCATH-ATHLBUTLER4-1:YES --venues kalshi

For size-aware estimates that evaluate the venue-specific fee curve at your exact price + qty (Kalshi binary, Polymarket CTF), see the SDK's preview() — there's no sequence preview command yet; it's coming alongside the rest of the pre-trade TCA work.

Level 2 — Trade

sequence buy <symbol> <qty> [flags]

sequence sell <symbol> <qty> [flags]

sequence buy  ETH-USD  50
sequence buy  ETH-USD  50  --urgency high  --max-slippage 10
sequence sell BTC-USD  0.5 --venue coinbase --limit-price 75000
sequence buy  BTC-USD  1   --policy twap   --horizon 5m
sequence buy  fed-decision-in-october 10 --venue polymarket --limit-price 0.55

sequence orders [--symbol <sym>]

List orders, optionally filtered by symbol. Status / side come back UPPERCASE.

sequence cancel <id>

Accepts either a graph_... ID or a full graph:...:node:seq node-order ID. Cancels every active node in the graph.

sequence amend <id> [--price P] [--qty Q]

Venue-agnostic amend for resting orders. At least one of --price / --qty required.

sequence amend graph_ab12:node_0:1 --price 0.55 --qty 15

Mode reporting:

sequence decrease <id> --by <qty>

Shrink a resting order without touching price. Errors if the reduction would leave ≤ 0 remaining.

sequence decrease graph_ab12:node_0:1 --by 5

sequence redeem <slug> --venue <venue>

Claim winnings from a resolved prediction market. Kalshi auto-settles; Polymarket fires a relayer POST.

sequence redeem KXBTCZ-26DEC31-T99000 --venue kalshi
sequence redeem fed-decision-in-october --venue polymarket

sequence fills [--symbol <sym>]

Fill history with venue, price, quantity, fee.

Level 4 — Automate

sequence init <name>

Scaffold a new algo project. Creates Cargo.toml, src/lib.rs, Sequence.toml, .gitignore.

sequence init my-strategy
cd my-strategy

sequence build

Compile the current project to wasm32-unknown-unknown and strip. Output ends up at target/wasm32-unknown-unknown/release/*.wasm.

sequence backtest [flags]

Run against the sim-engine with recorded Parquet market data.

sequence backtest ETH-USD --start 2026-01-01 --end 2026-03-01
sequence backtest --symbols BTC-USD,ETH-USD --start 2026-01-01 --end 2026-01-07 \
                  --capital 250000 --latency-model log-normal --output json

sequence preflight

Pre-deploy readiness checklist. Verifies venues connected, capital sufficient, risk limits loaded, no conflicting deployments.

sequence deploy [--skip-build]

Compile (unless --skip-build), push the WASM to every hosting edge, and start the deployment. Reads Sequence.toml for strategy name, symbols, initial params.

sequence logs [<name>] [-f|--follow]

Strategy stdout/stderr. -f tails in real time.

sequence status [<name>]

Deployment snapshot: per-edge position, P&L, fill count, callback latency.

sequence start [<name>]

sequence stop [<name>]

sequence undeploy [<name>]

Pause, resume, delete. stop does NOT cancel resting orders — handle those in your on_stop hook.

sequence watch [<name>]

Live deployment TUI — refreshes every second with positions, fills, and inter-instance mesh latency.

Level 5 — Monitor

sequence trace <node_order_id>

Nanosecond-precision lifecycle trace. Every event from SOR admission → edge dispatch → venue ACK → first fill → terminal state.

sequence intel <symbol>

Market structure snapshot: venue market-share, spread regime, toxicity score, quote-to-trade ratio.

sequence mesh [<name>]

Mesh topology for multi-venue algos: per-instance label, peer latencies, message counts.

sequence tca [<name>] [--symbol <sym>]

Transaction cost analysis. Per-strategy or cross-desk, optionally filtered by symbol.

Bundle subcommands

Bundles are compiled, signed, content-addressed artifacts that capture either an edge algo, a SOR policy, or an assignment policy. Used for reproducible deploys and policy staging.

sequence bundle compile-edge --wasm <path> --artifact <id> [--strategy <family>] [--risk-version <v>]

Wrap a WASM blob into an edge bundle. Defaults: --strategy mm-pro, --risk-version v1.

sequence bundle compile-sor --routing-model <ref> --impact-model <ref> [--slicing-policy <p>]

Compile a SOR policy bundle from a routing-model + impact-model pair. Default slicing: vwap.

sequence bundle compile-assignment --artifact <id> [flags]

sequence bundle promote --bundle <id> --target <t> --stage <s> --eval-run <id> --approver <email> [--break-glass] [--notes "..."]

Promote a bundle to a deployment stage (canary, pilot, production). --break-glass bypasses the drift-check gate — requires --notes.

sequence bundle list

Every compiled bundle with stage, promoted-at, approver.

Research subcommands

Research engine operates on recorded Parquet data — lives alongside the sim-engine.

sequence research scan [--where "expr"]... [--rank-by <field>] [--top N] [--evidence]

Predicate-based pair scanning. Repeat --where for AND-composed clauses.

sequence research scan \
  --where "venues ⊇ {binance,coinbase}" \
  --where "adv_usd > 1_000_000" \
  --rank-by sharpe --top 20 --evidence

sequence research profile <symbol> [--venue <v>] [--days <n>]

Deep single-pair profile: microstructure, cost model, regime classification. Default --days 7.

sequence research materialize --start <date> --end <date>

Batch-materialize profiles for a historical window. Writes back to the research store.

sequence research coverage [--symbol <s>]

Show recorded-data coverage: partition density, gaps, last-ingest timestamp.

sequence research feature-eval --feature <name>... --label <name>... --start <d> --end <d>

Walk-forward IC evaluation. Repeat --feature and --label for multi-feature/label runs.

sequence research monitor --bundle <id> [flags]

Performance drift check for a live bundle.

sequence research recalibrate --bundle <id> [flags]

Drift check → re-profile → optional auto-promote.

sequence research artifacts [--type <kind>]

sequence research artifact <artifact_id>

List / inspect research artifacts (profiles, feature evaluations, drift reports).

Meta

sequence update

Self-update to the latest release. Preserves ~/.sequence/config.toml.

Sandbox mode

Two ways in:

sequence buy BTC-USD 0.01 --sandbox         # one-off
sequence --sandbox buy BTC-USD 0.01         # global flag also works
sequence login                              # then paste a seq_test_* key — always sandbox

Sandbox fills settle against live NBBO with realistic slippage and fees. Balances + positions are isolated from your live account.

Exit codes

Scripts can parse the API error as Error: <message> — no colorization on non-TTY.
