What I’ve learned in my first CDF trading

I remember it happened just these days, I found an app called “Mitrade” which can buy etf, futures, and stocks on this website. Interested in trading, I invest 100 US dollars in my account and start my road.

Because I learned some technical skills to read the chart, I think I can handle the market myself. However, it turned out that I’m totally fucked up with my money. I lost all of it and got nothing back.
