A trader can produce up to 1000 pips in one day if he trades multiple pairs and if many of them are volatile. A trader can even produce up to 2,000 pips of gold trading in one day, so there is no limit on how many pips a trader can achieve every day during his strategy can accommodate that. And yes, some traders produce 500 pips per day, but do it every day really a difficult task. Maybe some brokers trade for almost a day continuously and make it that way. Or some traders use the big news release movement and get that big profit.
