Trading (revx order place / revx order replace / revx order cancel)

Place market and limit orders, replace (modify) open orders, cancel open orders.

Auth required. Make sure revx is installed and configured before running these commands. If any command fails with an auth-related error — Auth not configured, No private key found, Authentication failed (401), Invalid signature, insecure permissions, or a missing key/config file at ~/.config/revolut-x/ — invoke the revx-auth skill immediately and apply the fix yourself. Do not interrupt the user to ask them to run setup. Only escalate to the user for steps only they can perform (pasting the API key, registering the public key in their Revolut X profile, choosing a passphrase). After the fix, retry the original command.

Symbols use BASE-QUOTE format with a dash: BTC-USD, ETH-EUR, SOL-USD. Check pair constraints with revx market pairs (see revx-market skill).

order place supports --json or --output json for machine-readable output.

Behavioral Instructions for Claude

Human Confirmation Required

NEVER execute revx order place, revx order replace, or revx order cancel without explicit user confirmation. These commands move real money.

Before running any order command, present a confirmation summary to the user:

Order to place:
- Pair: BTC-USD
- Side: buy
- Type: limit @ $95,000
- Size: 0.001 BTC

Shall I proceed?

Only execute after the user explicitly approves (e.g., "yes", "go ahead", "do it").

For revx order cancel --all, warn the user that this cancels every open order and confirm.

Missing Parameters — Always Ask, Never Guess

All required parameters must come from the user. If any are missing, ask for them before building the command.

Required for every order:

1. Symbol — which pair? (e.g., BTC-USD)
2. Side — buy or sell?
3. Size — how much? (--qty for base currency or --quote for quote currency)
4. Order type — market (--market) or limit (--limit <price>)?

Never assume defaults for these parameters. If the user says "buy some BTC", ask:

• How much? (quantity in BTC or dollar amount)
• Market order or limit? (if limit, at what price?)

Optional flags (--post-only) can be omitted unless the user requests them.

Place Orders

# Market order (buy 0.001 BTC at best price)
revx order place BTC-USD buy --qty 0.001 --market

# Limit order (buy 0.001 BTC at $95,000 or better)
revx order place BTC-USD buy --qty 0.001 --limit 95000

# Post-only limit (maker only, cancelled if would take)
revx order place BTC-USD buy --qty 0.001 --limit 95000 --post-only

# Limit order with time in force (immediate-or-cancel)
revx order place BTC-USD buy --qty 0.001 --limit 95000 --time-in-force ioc

# Quote-sized order (buy $500 worth of BTC at market)
revx order place BTC-USD buy --quote 500 --market

Arguments: <symbol> <side>

• symbol: BASE-QUOTE format (e.g., BTC-USD, ETH-EUR)
• side: buy or sell (case-insensitive)

Flags:

Must specify either --qty or --quote (not both).

Replace (Modify) Orders

Updates an existing open order in place. Same URL as cancel, but with PUT.

# Change limit price
revx order replace <order-id> --price 96000

# Change quantity (amount is recalculated server-side)
revx order replace <order-id> --qty 0.002

# Change quote amount (qty is recalculated server-side)
revx order replace <order-id> --quote 150

# Explicitly allow taker execution (must be set explicitly)
revx order replace <order-id> --allow-taker

# Switch to post-only
revx order replace <order-id> --post-only

# Change time in force
revx order replace <order-id> --time-in-force ioc

# Combine — re-price and re-size
revx order replace <order-id> --price 96000 --qty 0.002

Behavior:

• Only fields you pass change; everything else stays as-is.
• If price changes on a buy and only one of qty/amount is provided, the amount stays and qty is recalculated. For sell, the opposite. If you change qty, amount is recalculated (and vice versa).
• --allow-taker must be set explicitly — it is never inferred.
• The order ID changes. After replace, the original order is closed and a new order is created with a new venueorderid (returned in the response). The original ID is preserved on the new order as previousorderid. Use the new ID for any further cancel/replace/get operations — the old ID will no longer be active.

Flags:

At least one of --price, --qty, --quote, --time-in-force, --post-only, --allow-taker is required.

Cancel Orders

revx order cancel <order-id>           # Cancel a single order
revx order cancel --all                # Cancel all open orders
