First, clarify: what is the difference between a simulador de bolsa and a virtual account?
Many people think that stock trading simulation software and broker demo accounts are the same, but that's not the case. At first glance, they seem similar, both using virtual funds for practice, but fundamentally, there are differences.
Simulador de bolsa is usually developed by financial education institutions, mainly to let you experience the feeling of investing—the adrenaline rush when opening and closing positions. They are essentially teaching tools, with well-known examples like "La Bolsa Virtual," "Wall Street Survivor," and the most popular "Investopedia Stock Simulator."
Virtual accounts, on the other hand, are provided by real online brokers, with the purpose of allowing you to test drive a platform before opening an account.
