thanks denis for the links

six months i work on pnn algorithm in forex

pnn algorithm are not difficult, but it's very difficult to have stable systems, and to found corrects inputs

i have add in my ea a function which calculate at each new bar, the results (in the past) of N PNN subsystems (N=1000) and choose the best ones to choose if Buy or Sell

it gives some good results, i'll continue to work

i don't dream about the grail, but only an adaptative EA, wich find the good pattern in each market condition

i would like to give my results to people who want to work in this direction

sorry for my bad english
