One thing that would support any type of daytrade, short term trade, position trade, etc. reporting would be if there was an easy way for people to keep a portfolio of the stocks they hold online in a place where anyone could see them easily. If the portfolio contained info such as Stock Symbol, Price bought at, Date bought, a Notes field to comment on type or intention of trade (daytrade, one week, position, swing, etc.), sell Date, etc. it would support the transparancy of people's posts. When daytrades stretch too long and people are wondering "did that person ever sell".. they could check the portfolio... etc
Just a thought
