But I would still disagree on this point few days is not enough to learn technical basics of trading. If in just 3 days you go with real money worth of $10, you haven't learned, let just say you are just gambling with small money and calling it psychology training….
There's no way you can learn trading in a few days, that is not realistic. Trading isn't like investment where you only need to invest and hold. Trading is far more complicated and complex to understand within a few days. This might be what those fake traders sell to people and they buy it, if trading is that easy to learn in a short time, many people would have been traders today.
The minimum time to master trading is 4-6 months but if you are someone who learn fast, then it might take you 4 months but learning it in just a few days is just unrealistic.
Actually, 3 days is enough for anyone to learn the basic mechanics of trading, like placing buy and sell orders, setting stoploss and takeprofit, and getting familiar with the trading platform. That's all, nothing more

As for the minimum time to master trading, that depends on how fast you pick things up, your background knowledge and a bunch of other factors..You can't slap a fixed 4-6 months on everyone cause we're not all the same.
And knowing how to trade doesn't mean you can trade profitably.
