Traders must need experience before they get profitable results from their trading. Also, the psychological part of trading is the most difficult and at the same time the most important part. That's why my broker, Eurotrader, offers traders a free trading psychology course. This broker also gives FX, shares, cryptos, indices, commodities, metals- trading services, and much more.
The more experience a trader has, the more likely they are to notice their own mistakes before they actually make them, that is why it is so important to trade as often possible, as much as possible.
