How to profit from option day trade?

[justlayman]

I have been studying for trading for over 2 years. With the current market volotity, it is very difficult to forsee the market midterm trend. I am currently interested in day trading and can predict the daily market direction with around 70% precision if I am allowed to start the trade around 10:00AM and close the trade at 4:00PM. The problom prompt out since the daily transaction of option is quite large. For example, for SPY (deep in the money call), the transaction for a single day is around 0.4% percentage of the profits you get from the day trading. This profits get is far less than the loss of a single mistakes in a trade. I am wondering how a good day trader deals with this situation?

Intra-day option trading seems such an alien concept to me with the vol surface changing so much. Too many variables to consider for a short term position. As mentioned-day trading.....stick to futures!
