I really think that short term traders have a little risk in not making their targets because of the range of their trading points, Yes this still count as gambling but with a little risk involved, And even though they are basing their assumptions on the previous market flow there is a high chance in winning by taking that chance than to do a long term trading.
Short terms trading is not for everyone and you most be ready to bear the lose because it is too risk to trade in that way. Those that desire to trade short terms should be ready to face whatever comes out of it and they should also be ready to learn from their mistakes.
