Forecasting reserves NN

I am working on a school project for predicting NN (neural network) stocks. I have yahoo market price data and I have normalized my data to an amount from -1 to 1, my inputs are date and close, but I am not sure what my result should be (I don’t know enough knowledge about stocks and market). I was thinking about having a date and open as my inout and close as my exit. I am planning to use MLP for my project, but there is something else I need to do after normalization. I'm not an NN expert. I am taking this course to raise my general class, we were only given one week to complete this HW, so I am not sure if I can learn to use the new software.

• my inputs are date and open after normalization, which should be the next step
• which neural network development tool do you recommend (for Mac and PC)
• Is it possible to use excel NeuroXL add on .. it works on mac

thank
