With the little knowledge I have, I have seen a lot of people scalping and making it than those that does a full trading(hours, days) but they tend to lose so easily can we say it greediness or it's not advisable generally
For me, there's no wrong with being a scalper. Because I believe that's their way of trade and there's nothing wrong, I can see a lot of people that are profitable when they do scalp trading.
But what I want to say is always think: "Not all the time, it's good to trade". There are also a lot of pairs you will try to look at and monitor if you are scalping.
So for me, scalp trading is just day trading, you either win or lose.
