Yes, but with strict limits to keep things fair:
You’re allowed to use a bot or EA only if it’s your own strategy and your own code.
Mass-produced or publicly sold bots are not allowed. If multiple accounts are detected running the same strategy, those accounts may be breached.
Fully automated, hands-off, 24/7 systems are still not allowed; you must be actively monitoring and managing your trades.
In short: if it’s your strategy and you control it, you’re good. If it’s someone else’s or something bought off a shelf, it’s not allowed.
