The bonus is added to your Standard account, as soon as the total volume of closed trades in your account reaches 10 lots/1000 microlots.
Example: you open a trade of 5 lots selling the EUR/USD pair, then you open another trade of 3 lots buying the USD/JPY pair, and finally you open a trade of 2 lots buying the GBP/USD pair. In total up to this point your total trading volume is 10 lots (5+3+2=10 lots).
As soon as the volume of closed trades reaches 10 lots/1000 microlots, you will receive a notification to the e-mail you provided during the registration.
Trades with 0 pips of profit/loss (the opening price is the same as closing price) are not counted for the bonus.
10 lots bonus and 1000 microlots bonus are not provided to the clients who trade using only prize money (Forexcup bonuses, etc.).
