In my case it´s the unbelievable, frustrating, staggering and deeply depressive ability to miss my exit prices for one tick in futures markets, a fifth of a decimal in Spot FX or a price unit in equity markets.
That lead to a so-called frustration-agression behavior throughout my trading career in which I destroyed countless laptops, computers, screens and mouses.
And before some smart a$$ comes up with the comment: why did you not change your exit prices and added a "buffer".
I did.
Result: I missed the buffer prices for a tick, too.
To be clear here: I am not talking about missing a couple of hundred bucks in profits. No, I missed millions in profits.
For quite some time, I thought it´s all about a curse!
Maybe one day, I will write a book about my experiences. I think it will be a hell of a read.
Good luck to all "tick missers". You have my absolute sympathy!
