when you use BO, two orders are placed.
One is for stop loss and another for Target.
in this case the target order ( sell order) will be placed at 110. ( 10 points).
Stop loss will be at 96 ( 4 points).
Now, whenever the stock moves 2 points in your direction, the stoploss order will change and move 4 points ahead. which in this case will be 100. So, if stock goes at 102 ( 2 points move) the stop loss order will automatically get updated to 100 .
I assumed that you are long in that example.
