Yeah, its just not the same in demo trading. The gain or loss doesn't hit you as it does in a live trade. I tried this at first as well and the emotions in actual trading is a lot different. You think to yourself that you're ready and won't be affected but when you actually see all the red and negative on your portfolio you'll really feel yourself sweating. In trading, you just really have to hit the ground running. What's good with demo trading is that it allows you to practice your entries and exits, assess whether you can identify the patterns and eventually familiarize yourself.
That is one of the disadvantages of Demo trading, so we as traders only make Demo trading one of the introductory methods, and despite the fact it will be very far from real trading. that's not what we need to take from Demo trading, but what we need to take is the system how it works and how to manage buying and selling. that's all, the rest we will be exposed to real movement. regardless of sweat and not when trading. it depends on how strong you are mentally in trading. Because the world of commerce will always have its own way of testing a person's emotional level.
