Well, I have being trading them with over 6 months. with my experience of trading over 5 years, I would say Blueberry market won't give you novice attractive packages like deposit bonus (though i get special 10% being a part of specific group of traders) , loyalty cashback and exotic events like demo contest etc. but they do provide highly professional support, high speed execution, ultra tight spread. i would recommend their pro account with raw spread. withdrawals also hassle free and it get deposited within 1 working day.
for cons, they only offer gold and silver for metals if you are a metal trader.
