When the Vix is above 20, the options tend to get wiped out in a whipsaw, when the vix is below 20, the options only seem to lose premium. So, intraday option trading is a very tough game.
some ppl are in/out managing trade very frequently and probably like it. I prefer taking a trade and sitting back without thinking too much. Maybe not suitable for such a style.
An example is someone like IT Jegan who could punch a few hundred orders in a day.
