OpenTradex — Paper Buy

Open a long paper position.

User arguments: $ARGUMENTS — expected form <rail> <symbol> <qty> [price].

Flow

Validate the user gave you all four pieces (rail, symbol, qty, optional price). If anything is missing, ask for exactly what's missing in one short sentence — don't re-ask fields the user already gave.
Pre-trade risk check: quote the open position count and current exposure: !node "${CLAUDE_PLUGIN_ROOT}/bin/tradex.js" risk If openPositions ≥ 5 or dailyTotal ≤ -50, warn the user and confirm before proceeding.
Place the paper buy: !node "${CLAUDE_PLUGIN_ROOT}/bin/tradex.js" buy $ARGUMENTS
Echo the fill price, position id, and remind the user: "To close: /opentradex-trade:sell <position-id>."

Rules

This is paper-only. Never claim real fills.
Price units: prediction markets (Kalshi/Polymarket) use 0–1 (probability); stocks (Alpaca) and crypto (Coinbase) use raw currency.
If the rail isn't enabled, tell the user to run /opentradex-trade:onboard first.
