Emotion is a money killer.
No way to avoid your statement but we need to follow our good emotions and need to learn the tricks of controlling bad emotions.
I think, in this case: meditation & yoga is much helpful! Even I see, pro traders are very much active on meditation.
I agree with you.
I've found that meditation to be helpful in controlling my own emotional state.
Not just in trading, but in life in general.
Automation of ones trading strategy for those things which can be automated is also a massive help as well.
If it looks too good to be true, it's probably a scam! Let the buyer beware.
