The trader in an effort to learn the magnitude of the pin bars dives into trading the setup but has a limited account size. he is told that he should risk a % of high account per trade. Since this trader is a tester he tests the edge needed to produce profits with this start. The trader runs the test at 50% win rate at 1:1 and notices something odd. most traders consider 1:1 r:r at 50% win rate to be break even trading. But the numbers don't reflect this. What is reflected is a slowly accruing loss.
