danphe,

If you are looking for cheaper options, sogotrade is even cheaper. They just charge $3 per trade. I am not sure about the additional hidden costs but I would recommend you to have a look at it.

I have been using Zecco for about a month and they just charge $4.5 per trade. There are no additional costs involved (besides some insignificant transfer costs). I am also not in a position to give proper thoughts about zecco because I am new to trading itself, let alone zecco. So if anyone has any ideas please enlighten us.

Cheers!
