Some use NN quite successfully in real time. One example (hope it comes through) is shown below in which equity increased by a factor of 3 in a year or so. The software is one of the standard packages but I don't recall which one. Charts are at the MSN Group "MaxProfit." As with any NN, this is not a canned output and requires quite a bit of work to get a profitable, stable model. But it can be done.

I have tried some [most promissing] NN in the past.
My test was quite simple : I ran the algorithm for a 1000-bar famous
stock and saved the result. Then, 10 min later, I ran the same test
on the same stock. The new result was quite different ["quite" means
a "Sell" instead of "Buy"]. I repeated 2-3 more times the test. I
also noticed differences in the NN training series. I carefully
copied my tests and sent them to the NN company with my Best Regards.
I still wait for their reply. I am patient enough but, I am afraid
they will not send any kind of reply. Then I sent a suggestion for
their own use. Instead of running 100 individual NNs for the 100 N100
stocks [and enjoying, perhaps, the perfect 50%-50%], it would be
better to run a composite StochD for the whole N100 market. It was
the day of a bearish MeanStochD divergence and, my NN-less prediction
was the beginning of a [new] downtrend. They didnt make any comment.
I suppose they make money selling NNs. I also suppose they trade the
MeanStochD divergences. But, I have not received any kind of
confirmation for these thoughts. The [absolute] silence of these NN
vendors is, perhaps, the best way to communicate in the 21st century.

PS : If anybody knows an NN which give the same output for 10 tests
on the same 1000-bar data series, please let me know...
If you also know any NN software "understanding" the directionality
of the market, please respond.
