What 12 Pairs? When you say '12 Pairs', just wondering what 12 pairs you mean? Dumb question I know but been wondering for a while.
this is a great EA by the way, bout time you started locking your ea files man.
Actually, the strategy reminds me of the simple 'over/under/buy/sell' used by some in the options world.
simply add the total numbers of buy and sell orders, divid by two, if this number is above the actual selling price, place a sell with a very short TP (or close on oposite), if the number is below, place sell. Easy.
