BTW I would not call it complacency but fatigue and inability to stay on point, razor sharp, ALWAYS.
As I am also a discretionary trader, to stay on point, razor sharp, ALWAYS, is essential.
After the close, I every day, review my trades and what I should have done. Each time when I trade differently from what I should have done, it is because I lost concentration or got distracted. The motivation is partially gone.
The higher the profits go, the lower the concentration goes after a while. After trying out several solutions, I found out that the only thing that works is to punish myself if I get "lazy".
So if I have to punish myself, I force myself to do something that I really hate. Each punishment consists of a six month period that, outside the US trading hours, I have to get up at 5:20 AM, eat, and then punish myself for the next six hours. It was horrible but it worked. It was so effective that, till now, I had to do it only once.
As it is very heavy physically, I lost a few kilos and my condition is much better. So a win-win.
Psychological things didn't work at all.
Just make sure that your are more afraid from the punishment then from not trading well.
It's comparable to torture, but still at an educated and human level.
if I compare my weekly profits, some weeks can be 10 times better than other weeks. But that is irrelevant. What is essential is that you see what the market offered that week, and what you could catch. Some weeks there is a lot to catch, and some weeks there is not.
If you followed your system, you should feel good. If you did not follow your system you should feel bad.
