How to define consistent profit? 5% return in 1 month? 30% return in 1 year? $10,000 per quarter? $500 per day?

The fact is, it is very difficult to make consistent profit in a given period. Some gurus that claim they can make consistent profit are actually lying.If traders pay too much attention in making "consistent profit" in a fixed period, their decision in trading, which is supposed to be objective, will be irrational.

If traders would like to determine their performance based on consistent profit, they should lengthen their time frame to at least 6 months, preferably 12 months or even 3 years.
