A lot depends on time frames, and how many trades per day you average. If emini trading, for instance, and you daytrade or intranight trade.........intraday {9 til 3} will usually produce 2 runs per day. So, if you trade the 2 runs per day and one of them will make mucho dinero and one will not be a money wagon, but loss is minimal each time, them %'s is not an issue. That is, % of winners compared to losers. Even if 2 losses per day, the runs that make money are bolstered by the r/r ratio being acceptable and smart.
