This is a question that many traders ask, and the answer may surprise you. Many people believe that they need a lot of RAM in order to trade effectively, but this is simply not the case. In fact, you only need around 2GB of RAM in order to trade effectively. Of course, if you want to use complex trading software or run multiple programs at the same time, then you will need more RAM. However, for most traders, 2GB of RAM is more than sufficient. So if you're wondering how much RAM you need for trading, the answer is around 2GB.
