I am with FreshForex broker and I had taken their 101% tradable bonus which doubled my initial deposit. This bonus is a margin calculated one, meaning this bonus is added to your initial deposit and acts like your own money. If there is some loss, it is taking from this combined amount & not from initial only! Very cool, isn’t it? But explore other cool features like no slippages or re-quotes, ultra-low spreads/commissions, 1:500 leverage, forex education, good customer support and fast withdrawals!
