In your opinion, can someone trading without experience or knowledge?
Yes you can, it’s called speculation.
But, the gap between gambling and speculation is too narrow (or is it the same thing?).
The only knowledge we must know before doing trading is knowing how to use the trading platform.
But if your question is, “can someone gets profit from trading without experience or knowledge?”,
The answer is, yes they can. But their chance is is lower than the educated and well-trained trader.
But, even a pro trader is a noob trader when they started it for the first time, right?
You do mistake first, and then you will learn.
