Nonsense. “Stopping when you hit a weekly goal” is a psychological game that is actually detrimental to your success.
How do you know that the remaining days in the week will be losers if the previous days in the week were winners?
Winning and losing days are randomly distributed. You could have a string of winners or losers in a row and there’s no way to know ahead of time. Therefore you don’t know ahead of time if it’s going to be a winner or a loser, and therefore there’s no reason to stop trading when you hit a “weekly goal” unless you just don’t feel like trading anymore.
What if you make $1,000 by Wednesday. How do you know you would lose it all on Thursday? How do you know you wouldn’t make $2,000 on Thursday? You don’t. If you do, I would like to invest a significant amount of money with you.
Unless you have some way to know if your future trades are going to be winners or losers, then how do you know if you’re going to “lose everything you gained”?
Look, there are 5 days in a week. You have no idea which days are going to be winners and which days are going to be losers. there’s nothing magical about starting on Monday and stopping on Friday. Trade the days you want. You have the same chance of making money on any day that you trade as you do on any other day you trade. There’s no “stopping when you hit a weekly profit level.” Trade whenever you feel like trading.
