For me, when you just trade randomly without a clear pre-planned strategy to follow in all your trades, that is gambling and high risk.
And that is common to 90 5 of the new traders. They read some fake article online how someone managed to make $100000 or so in a week or so and then join that trading exchange using his affiliate link. Most of them will fail as they simply gamble ( pick the same trade used in that article without checking its relevancy or current performance).
My point is that, we should have good knowledge, skills, and pre-planned trading strategies to follow so that emotions will at least be minimize in our trades.
Most of the people are not patient enough to wait till they require these. Best option is to practice on demo platforms before doing any real trade.
