Are trading bots legal?

I'm curious about the legality of Trading Bots in the cryptocurrency and finance industry. As an automated tool designed to execute trades based on specific rules or algorithms, do trading bots fall within the bounds of legal trading practices? Are there any regulations or restrictions that traders need to be aware of when using these bots? Additionally, are there any risks or potential consequences associated with their use? It would be great to get a clear understanding of the legal status of trading bots in this field.
