Why amendSpreadOrder needs a policy

This tool modifies existing trading orders by adjusting prices and quantities. While modifications are reversible (orders can be amended again or cancelled), this is a Write operation that directly alters financial instruments and trading state on the Bybit exchange.

From the tool's definition Tool description states 'Amend (modify) the price and/or quantity of an existing spread trading order' and 'Adjust the price of an open limit order' and 'Modify the quantity of an unfilled or partially filled order'.

How to control amendSpreadOrder

PolicyLayer is an MCP gateway — it sits between your AI agents and Bybit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for amendSpreadOrder:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "amendSpreadOrder": {
      "limits": [
        {
          "counter": "amendspreadorder_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

amendSpreadOrder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
