I'll give you break even for that day but thats the best I can do cause I saw red. And as much time as I spend updating and calculating these things I can't go back 2 days to try and refigure things out. I do keep everyday saved just incase I mess up.
This might clear things up
I use a judgement call I don't always go by open price sometimes I go by previous day.
If a stock has major news at 5pm or 9 am and someone uses it as there pick then yes I go by open price.
If someone picks a stock at 3pm on a Sunday on a stock didn't have news and miraculously runs and even opens higher with no news then yes I'll give that stocks previous days close. because thats one hell of a pick. How would they know the stock was a runner?
That same runner could of colloapsed 50% in a day noone knows so I use my judgement.
