Can I use a bot or a trade copier?

Yes. What is banned is narrow: cross account hedging, microscalping and high frequency algorithms.

Automated systems and copiers are permitted, and so is genuine scalping and averaging into a position.

The bans are aimed at manufacturing a payout rather than at trading: hedging the same instrument across two accounts, microscalping to work against how a simulator fills, and high frequency algorithms.

You carry the consequences of your own software. A bot that breaches the account has breached it.

At a real firm these are flags for a human to look at rather than automatic breaches, and none of them is enforced automatically here either.
