for now I only trade short-term, sometimes I open margin trading with care. In fact, I consider that long-term trading is not a type of trader but an investor.
If there's one thing I know, It's the fact that Long term traders are not entirely investors. Long term traders have the larger opportunity in my opinion. Short term is mainly for scalping and the potential profit is usually small. Compared to that of Short term traders.
Short term or long term trading, none is better than the other. They both have their advantages and disadvantages. In all, It depends on the person and which TFs they're flexible with.
