Yes, each beginner will have their own amount of time that needs to be spent on a demo account. After all, there you will need to not only study the functionality of the platform, but also create your own trading strategy, optimize it and bring it to a working form. For example, it took me more than six months to do this. For someone else, it may take more time. Only after that I opened an ECN account with my broker fxopen, which allows you to open it starting from $ 100. Such a real account was small because trading on a demo account and on a real account is very different due to the psychological component, because on a real account you are already risking real money, so trading here is more emotional and you need to learn to cope with this and only after that you can risk more money.
