Over60 is right as the HPEA is a helper for different manual and hedging strategies, it makes normaly no sense to use the EA on 28 pairs, as it will be very difficult for you to follow all pairs...
Try to understand the EA in using it on one pair, maybe with different settings to understand better the functions, and to understand how to embed the HPEA in your strategies. Ask any questions here, as there will be for sure always someone to share his/her experiences with the EA.
