Perhaps the biggest shortcoming of Robinhood is the fact that it does not offer a simulated trading account of any kind. This would be especially helpful for option traders as an educational resource, but despite the fact that competitors have done so, Robinhood is still without this feature.  Simulated trading for options is particularly important to new traders. This kind of trading experience helps new traders learn how option pricing changes over time. It is difficult to comprehend how option prices are influenced by changes in the price of the underlying security, as well as by the decreasing amount of time until expiration. The experience of paper trading allows new traders to learn this more effectively.
