...... How do you instill discipline into yourself ? Prevent yourself from making the same mistake again and again...?
I would like to share what could work for me.
Keep a banner on your desk-top, striking to the eye, having illustration/inspirations or reminders which would prevent you from doing something again and again.
Keep this kind of posters around your trading terminal
Recording them in diary and giving constant review works great
And, if you think you repeat a mistake again and again, then it is suppose to launch great deal of stress. Analyzing and coping with the habit you need to correct becomes obvious remedy for the stress you experience. Thought, it is not good to stress yourself for everything that happens in trading, fatal errors must give stress. That stress is the evidence of self awareness. The constant awareness and monitoring your habit is really a matter of challenge. Still we have no other go to do with. Once you follow your own rules and become aware of the fact that following rules pays you, then you would not make the mistake again.
We must realize it that staying with our own rituals which works for us, is the essence of what I would call a "trading habit"
IMO, discussing trading systems and methods with others, once you crossed the level is not good and could lead invite many problems again and again you have to deal with.
Happy Trading
