I have been day trading for 15 years.
My system gives about 30 day trade signals per month, and that is enough to keep me busy.
These days I also have a monthly loss limit: Down 6% for the month I stop trading for the rest of the month.
So if the month starts out bad i don't even take all 30 signals i just stop.
Keep powder dry for the easy months that are profitable from the get go.
Some times I hit the monthly loss limit 3 months in a row
Having to stop day trading is hard, because its very addictive.
And that is main problem with day trading its so addictive and sometimes rage inducing that you cant stop yourself and losses get out of control.
