the option volatility has increased by 20 points- to 57! Dont buy staright calls- the option prices will collapse on wednesday- regardless of the result. This is a fundamental mistake most beginners make!
if you have long calls hedge it by selling equal number of calls against the long position I personally prefer the 380/400 call spread!
The norm is around 27-28!(for volatility! Buying straddles- means you are expectinga huge move- yes they are very costly- you can do a straddle/strangle trade to mitigat some of the volatility- but you will be limiting your gains(depending on the strike prices of the strangle you sold- try to look for a 1 :2 risk reward- when doing these spreads!
very good point. I have bought calls at this point. Will do bullish spreads before EOM tomorrow. Only point I would like to add is you can still do a good spread before EOD tomorrow at a better price point
