I know absolutely nothing to NN.
but in one of my primary bible of trading " Encyclopedia of trading
strategies" the best tools were NN , genetic algorythm(GA) and BO
models for entries and GA for exits.
there is a NN addon for tradestation called safir XP and that's the only
NN package that 's not suffer of criticism.
NN are certainly a good tool, and often we throw what we don't understand.
