I would like to know if you are working on a new feature to have the possibility to work with Predicting Price to complete Neuro-Lab extension ?

No. Neuro-Lab won't predict prices and it's a misconception to think that it will. N-L creates a generalized bounded indicator whose value is greater when the inputs conditions are more likely (based on training) to maximize the output target.

So, you can't get a NN that says "GOOG will close tomorrow at 542", but you could train one to try to predict tomorrow's price by using that price in the Output script. It doesn't make a lot of sense to me and I've never tried to do that, but it seems to me that an unbounded output would produce unpredictable results since the NN output is going to be bounded anyway.

I'm sure this has been discussed in these forums before, and you should read everything that brucev has written. He's the expert.
