# Need to add a column to my watch list: "Change from trading day Open

I am trying to add two colums to my TOS watch list:
The first one is the difference between the stock value at opening on the trading day and the actual value of the stock price. This will be in dollars.
The second one is the same as above but expressed in percentage.
Would anybody know how I could get this done?

Try this in a watchlist column

Ruby:
``````def o = if SecondsFromTime(0930) == 0 and SecondsTillTime(0930) == 0 then open else o[1];
def PercentChg = 100 * (close / o - 1);
AddLabel(1, "Open: " + AsText(o) + " %Chg: " + AbsValue(Round(PercentChg)) + "%" , Color.BLACK);
AssignBackgroundColor(if close > o then Color.GREEN else Color.LIGHT_RED);``````
