Bots are pieces of software which are permanently sending requests to the EA servers in order to stay updated and take care of automatic processes. The owner just has to indicate the price he’s interested in buying specific cards and, when they appear in the transfer market, the program makes the buy for him. The majority of these programs also automatically makes sales. The big difference between an AutoBuyer and an AutoBidder is that the first buys by BIN (Buy it now) and the other one buys by BID. Some more modern bots can also buy and sell without any intervention from the player. However, in all these cases the risk of being banned by Electronic Arts is really high.
