Goal reached? Stop trading that day

My question was, how many of you stop trading when u reach your goal for the day? Also do u have a downside limit for the day?

A problem I had when i began trading 3 years ago was that i was having 4-5 hundred dollar days from the beginning, but i was never satisfied. I always wanted more. And I always ended up giving back the money I was up and eventually ended up in a huge hole. This set up some nice psychological patterns that i am still dealing with today.
…If i had a firm goal and respected it I would have been making some nice money from the start and would have saved myself from some traumatic experiences. At the time I just did not have the experience to protect my day without giving it back. I always traded great off the open and kind off struggled for the rest of the day.

Over the years I`m learning to leave after reaching a certain point and during those periods have always had great months but I still wonder (the same voice that made me wonder if i should stay 4 years ago) should i be leaving. Well for the majority of the time when i stay, I end up losing money or churning, but there have been several periods where I would stay and had good profits. I guess my point is, i was just curious to see how many of you stop when your up a certain amount of money regardless of whats going on???
