Script does NOT work after adding AddOrder()

[AlanChenMB]

While I trying to use AddOrder to place a buy order, it is weird that in case I add the 2nd line (AddOrder) then my script does NOT work but if I comment out my AddOrder command in script then both before/after alert works.

Wondering if someone know the possible reason?

Alert(1, "Before AddOrder", Alert.BAR, Sound.Bell);
AddOrder(OrderType.BUY_AUTO, close > close[1], open[-1], 1, Color.ORANGE, Color.ORANGE, "Sample buy @ " + open[-1]);
Alert(1, "After AddOrder", Alert.BAR, Sound.Bell);

No.
You cannot use AddOrder to place a buy order.

When adding AddOrder functions to a script for backtesting; make sure that you first copy your script into the Strategy tab. The Strategy tab is to the right of your study tab.
AND THEN put in your AddOrder statements.

Putting AddOrder statements into scripts located in the Study tab will not work.

You can use AddOrder to backtest and see what historical orders your strategy would have made.
It is a good way to find out what else you need to tweak to make your strategy more successful.
