I am primarily a swing trader and I always try to buy calls on a down day. That is the only way to get cheap calls. If you jump on an uptrend with calls like you would with the stock you will be paying too much. If you buy on a friday afternoon you are giving away time premium. If the underlying moves against you on top of those other two factors then you are screwed. If you don't understand the first two factors I mentioned then don't trade options anymore until you do.
A good example would be the action of friday and today. Those who bought calls on friday afternoon and held to today got triple whammied. Whammy #1 was they paid too much for the contracts. Whammy #2 was loss of time over the weekend. Whammy #3 is the underlying moved against them this morning.
