You must be a master trader when trading big and quick. This is been done by many and they also succeeded because they are well prepared when doing this. So, yes this is effective way also and many are doing this, but in quick trading you must be watchful every seconds od the marker movement so that when it hit high you are wide awake when it happens, and do a quick selling if you want to.
I bet that even the master trader or let say the pioneers on trading wouldn't do this because this was really very risky. Expect that if you would do it you'd only gonna end up either failed or losing. Trading is not a simple thing to do quickly you must pay attention and time in everytime you're gonna do this if you are aiming for a profit.
