Hi Bruce,
It has been a long time since I used the prop firm robots, but as far as I can remember there is no way to change the set files to only allow the EA to trade in one direction. If you had EA Studio you would be able to add a long only or a short only indicator to the source code then you could select the direction in the set file.
The EA’s are created using 5 years of historical data that includes many periods of upward and downward trends. The indicators in the EA’s have been chosen so that overall the EA’s would be profitable.
This is where using multiple EA’s help to minimize risk. The idea is that when one EA is going through a countertrend the other EA’s will be compensating for the EA going through a losing period.
In my opinion if you just want to have an EA that will just trade long or short would require you to determine the trend and then set the EA to trade only in that direction. If this is what you want to do then you really don’t need the EA you can just determine the trend and manually enter a trade in that direction.
Alan,
