separate

Calculate contract-based futures position sizes from a direction, entry, and stop-loss, using verified per-symbol contract specs (multiplier, tick size, tick value). Use when the user asks how many futures contracts to trade, wants to size a futures position (ES, NQ, ZB, GC, CL, 6E/E6, VX, BT, ...), or is handing off a contrarian-setup-gate READY_FOR_PLAN direction/invalidation_level for sizing. Pure, offline calculation -- no API keys, no network.

When to use

• After `contrarian-setup-gate` reaches `READY_FOR_PLAN` and you need a contract count for the confirmed direction and stop
• User asks "how many ES/NQ/GC/CL/... contracts should I trade?"
• User has a futures trade idea with a known entry and stop and wants risk-based sizing
• User wants to check the verified contract spec (multiplier/tick size/tick value) for a symbol before sizing (`--list-specs`)

When not to use

• Equity share-count sizing
• Deriving entry prices
• Sizing setups not confirmed as READY_FOR_PLAN
• Using explicit direction/stop with gate-json
