I just discover scalping lately. I don't know but I like its way of earning in short term. Then I noticed one of my friend is doing this. I'm kinda curious so I asked him how does he make profit out of it. Then he said his target was 20% gain before going out the market. But there are times he holds the coin longer than he expected because of the unpredictable market. Stop loss is also not in his line. He sometimes earn, sometimes unexpected comes, sometimes lose. I guess the strategy itself is OK but requires much deeper analysis.
