Hello, I have just made a stupid error entering an order this morning and I am really pissed. It didn't cost me much but it's really frequent in my trading... I estimate it cost me 10 % of my performance annually, not kidding... Thanks god I'm mostly automated and it reduces the number of occurences.. I think I've made every possible error ranging from forgetting rollover day, a zero in the limit, trading wrong contract, let my platform run on holiday 2 hour trading... One of the best being the day I was trading with the book and bought at ask instead of joining it... Now I try to concentrate more but I still make errors. These things really make me angry... I don't mind losing because of my strategies but I can't bear stupid errors. Have you got experiences, methods... to work on it? Thanks.
