it really depends on the your profit taking appetite. people who want short term gains or require funds or people who earn small profits like to save as much as possible on the other hand for traders who trade a lot have a lot of experience and know they can recover whatever they lost are less concerned 'bout the fee.
I'm surprised to see that this is such a popular opinion, that somehow for some traders out there the fees that they are being charged are not really important, and nothing could be farther from the truth, if you are a trader you should care about every single thing that cost you money, you should care about being able to enter the market with as little slippage as possible, you should care about your stop loss and about the average profit that you can get per trade and you should care about your fees as well.
