Bonuses that require some real market activity from the traders are called trading bonuses. Sometimes Forex brokers offer money bonuses to the traders that have a high trading volume (10 standard lots and more) by giving away a part of their profit (which comes from currency pair spread) to increase the traders' loyalty and provide some incentive for further trading. Forex trading bonus is almost always set as some fixed amount of dollars rather than percentage. This is a great bonus type for the scalping or intraday traders with a large enough account. The more trading positions are made the greater are the chances to earn such bonus. Unfortunately, long-term traders and traders with small accounts won't benefit much from the trading bonuses.
