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
@OP you may have seen more scalpers make more profit from the market because it can be more easier to predict short term market movements than the big moves, and that requires lesser expertise.
Scalping is the strategy to make small profits from small market movements. Scalping may interest you as a beginner in trading because of the satisfaction that small profits will be giving you then, but as you progress and your experience increase, you will want to try setting your trade for longer time to be able to profit more from the market.
