Your numbers seem a bit high... averaging 50 ticks/day, least of all 200, with losing days, seems absurd... but what do I know.
Pips don't tell the story, $'s do. Someone may boast of making 50+ pips a day but is only trading 1 mini (or smaller).
Well, he did say "glean," heh. glean -verb (used with object) 1. to gather slowly and laboriously, bit by bit. ... Of course, the poll categories are absurd. Asking how many forex day traders glean 50 / 100 / 200+ pips a day, on average, is roughly the same as asking how many ES day traders glean 7.5 / 15 / 30+ points a day per contract.
