Risk Guard

risk-guard

Stateful session tracker. Records every trade, enforces the per-trade risk cap and daily drawdown limit, and acts as a veto gate for bybit-trade.

When to use

• "Initialize my trading session at $500 equity"
• "What's my P&L today?"
• "Am I allowed to risk $30 on this?"
• Called as a subprocess by bybit-trade before every order (not by the user)

How to run

All subcommands accept --state-file PATH (default: ~/.claude/skills/risk-guard/state.json).

# Start a session (overwrites existing state after confirmation)
python risk-guard/guard.py init --equity 500 \
  [--per-trade-risk-cap 25] [--daily-drawdown-limit 150]

# Veto gate — exit 0 if allowed, exit 2 if blocked
python risk-guard/guard.py check --risk-usd 25

# Record an opened position (called by bybit-trade after a successful order)
python risk-guard/guard.py open \
  --order-link-id clive-SOLUSDT-1719000000000 \
  --symbol SOLUSDT --side long \
  --qty 11.2 --entry 148.20 --sl 145.97 --tp 151.16 --risk-usd 25

# Close it
python risk-guard/guard.py close \
  --order-link-id clive-SOLUSDT-1719000000000 \
  --exit 151.16 --realized-pnl 33.15

# Human-readable or JSON status
python risk-guard/guard.py status [--json]

Block conditions (exit 2)

check exits 2 with an explanation in stderr if ANY of:

• state file missing (you must run init first)
• realized_pnl per_trade_risk_cap (this trade would breach the per-trade cap)

There is no override flag. This is intentional — bybit-trade invokes check as a subprocess and treats any non-zero exit as a hard veto.

Exit codes

• 0 — allowed / success
• 1 — argument error (missing required fields, invalid state)
• 2 — veto (cap or drawdown tripped, or state missing)

State file shape

Human-readable JSON. Open it. Read it. Don't trust.
