Firstly, note that only the logic for the long positions is input in the indicator slots. You don't need (and you are not able) to input the logic for the short positions. Forex Strategy Builder does it automatically. For example, if you want to open a long position when the market price has reached the upper Bollinger Band and a short one at the lower band, it is enough to choose Bollinger Bands with “Enter long at the Upper Band” logic. This is sufficient for the program to perform the requested logic in both directions. Forex Strategy Builder always performs what we have set in the long position slots and automatically determines the mirror logic for the short position.
