As I tweak the original AIM system to match the Forex trading, which entails leverage, I believe it might be possible that when the price keep going up by x%, then there'll be switch of place from long to short. This should be fine, provided that there would be
1. Sufficient margin in the switch point
2. Switch stage is some where close to historic resistance?
Among those assumptions in AIM system is the prices is present in a range in a big scheme of things. This is most likely a safer premise for exchange rates. I need to think about it on the weekend.
