They are not really cheats. They do what you are supposed to do normally, but in this case, they do it without having any second thoughts or trying to see the nature of the market. They sell based on where you tell them to, and they buy based on how you have programmed them. The volatility of the market though makes one to get the best from bots but that is if you have a very sound strategy. Nevertheless, the same volatility can also mar sometimes, so it still depends on the market you are playing with.
