Trading is hard

A bit of background; I studied economics and finance for 4 years and now for the last 4 years I am working in a retail brokerage. I have also traded for a few years on my own while working and studying and I can safely say that trading is hard. The majority of our clients lose all their money and cannot trade even if their life dependent on it. I have reached to the conclusion that even if a retail successful does exist, they are simply an outlier. Combination of leverage and spreads is dooming. The only way to beat the market from what I have seen is that you need to find a true edge. The edge needs to go beyond charts and single instruments. It can either be a combination of instruments or brokers. On the other hand, I would advise that you stop trading and invest. The difference is that the second one is not looking for a quick buck but simply trusting the process that markets will go up as a whole in the future. You do not have to cherry pick stocks or any other instruments. Simply invest in cheap ETFs.
