Besides hitting a stop limit? I've had a few days over my the last ~14 years that I think I would have been best calling it a day. Twice had semi drivers try to do a turn around in a driveway where the wires were low and snag wires. I had the power go out and was on the phone and experienced pretty big losses for me. Power came back up before markets closed, and I jumped back in, and added to losses. I will add the trades when the power blew were profitable, but they hit my stops while trying to close on the phone, and then I was way to agitated and should have not traded again. I have had other situations similiar throughout the years, and admit I kept trading, and for me, it has always been a mistake. Today was another unique day and I am walking away. Bleeping, f'ing cats had a fight and disconnected my network connection. As I was on the phone closing 2 positions, the dog puked, on my foot, and no I am not exagerrating, on my damn foot. I actaully owe the dog, as for whatever reason, it made me stop and think. I am too fired up and need to at least take a break. It made me think, and take a break. Shit happens when you are trading for yourself, and I am curious if anyone else has seemingly bizarre guidelines to stop druing the day? I have added, literally to my trading plan, that I will stop for the day when the unexpected happens. Not limit up or down, but tech, or whatever stupidity can happen. I post now as I am done for the day. I closed my charts, and reprinted an updated trading plan. Stupid, maybe, maybe not. To me I think it is logical, as what I describe takes me out of my plan, and I am human, so being able to acount for it and have a plan of action, or no action is a good part of a plan.
