I have mentioned this before, but I have seen so many newbie traders make very naive statements such as "I only want to get 5 pts per day trading this" or some other arbitrary number, not based on any market reality, but on some monetary figure they seem to like the sound of...The reality is the distribution of gains and losses is not so easy to predict, even if you are 100% discretionary...
Take, for instance, this past Friday...For some they might have caught one small move off the open and made their 5 pts and quit for the day...Others may have traded all day and lost their 5 pts for the day...There is a serious randomness to returns over the short term...And another thing that you have to watch for is the tendency to say, "once I am up 2-3 points I will quit for the day", which is equivalent to saying once I capture a minimal amount of noise I will quit and then start again with that exact amount of risk tomorrow...
Many of these questions arise because people have not considered the alternatives...What happens when you are battling back from being down 10, when all you wanted to make was 5..What happens when you are up 3, want to make 5 and then lose the 3 and go back to 0...These are just a few of the myriad possible occurrences during any given trading day, which goes to prove that it is very random...The best thing to do is to simply max out the days when you are winning, so that when you are in flow with the market one day, you do not quit, but you push it and try to hit a much higher threshold...That way, when you have the losing trades they will not knock you right back to 0...
If you do a good enough job, eventually you will average your intended goal, but you cannot predict the outcome of the event and cannot "micro manage" too finely or you will find yourself developing a certain anxiety over each and every trade...This will certainly destroy any "flow" you want to create in pursuing your goals...
