WHY IT NEEDS A POLICY

Why amend_spread_order needs a policy

Amending a spread trading order modifies an existing financial order on Bybit exchange. While it modifies trading state (Write), it doesn't directly move money or commit new financial obligations — it changes parameters of an existing order. However, amending orders on a live exchange has high blast radius as it can significantly affect trading positions and financial outcomes.
