of course there's a safety, it's called basic math. the bot knows at how much it bought and how many coins, and you have set it to sell at minimal gain such.such percent ... and the bot can math. so it can't sell at loss if you don't set it that way. for example, if you would have set minimal gain of 0.3 and the fees for the trade would be 0.4% combined, then you would have a bot selling at loss of 0.1%. in any other case, no way when the bot is running in auto trade ... except for tanking coins which fall really low, so the stop limit mechanism gets triggered, or if you activate panic sell, which will sell regardless of gain. panic sell needs to be activated from the setup, which means the bot is no more running on it's own, but you forced the sale of coins over it's working algorithm.
