Majors-only Guardrails

OFFICIAL· Knowledge · by Moby

A Moby Guardrails setup for majors and tokenized-stock traders: a market-cap floor that keeps the agent out of micro-caps, and only the order types you use.

About

Guardrails are the limits Moby enforces on every agent trade, whatever the agent says. This setup keeps your agent on established assets.

  • Minimum market cap. Buys below it are refused. The presets stop at $10M; type a custom figure, such as $500M, for a majors-only floor.
  • Order types. Leave on the ones you use (market, limit, trigger buy, DCA, take profit, stop loss) and switch off the rest.
  • Spend limits. Set a max per trade and a max trading volume per 24 hours that fit your account. Sells into USDC never count against them.

You set these in the Moby app. The agent reads them with get_my_guardrails and cannot change them. Coins with a red safety rating are always skipped.

Install

  1. In the Moby app, open your agent's settings and find Guardrails.
  2. Under What it can buy, set a minimum market cap (enter a custom figure above $10M).
  3. Under Order types it can place, switch off the ones you do not use.
  4. Under Trade limits, set your max per trade and max volume per 24 hours.
