It removes the position from your position monitor, you have to know how much commissions Redi is subtracting from your P/L and factor that in.
For example if you go to average price and see that you have sold KO @ and avg. price of 58.00 and that Redi is taking out .012 in commissions then you would go to Equity Doneaway
on REDIplus tool bar then buy it @ 58.012 or you'd buy it if you were down on the day.
The most important thing is to make sure you use Quick Insert and not FLOOR.
You can right click it in Message Monitor under the Equity Doneaway header and delete it which restores it to your position monitor. This is what we do with our conversions. Don't be afraid to play around with it.
