Oh and by the way, Trader B lost 14 trades in a row at one point. Do you have the discipline to continue trading your system even in the face of 14 consecutive losing trades? Most don't - but then again, the majority of people lose money in the markets.
Is it discipline to continue trading after 14 consecutive losing trades or is it a lack of self-awareness? Is the losing due to "randomness" or due to changing market conditions that erode system edge? Trading isn't like poker or gambling where the probability is fixed (for example: knowing that there are 52 cards, 13 of each suit, therefore you have X in the deck to make a flush, etc). The game can change the next day.
If you lose a coin flip by calling tails 100 times after 100 attempts, you're probably a sucker if you still think it's a fair coin.
Just something to think about. No right answers...
