Hi, 

I have just now downloaded a virtual trading app and bought and sold and made no profit. (Within a minute)

My question is

1. How long must i keep my investment in hours to see a change in stocks value?

2. What valuations must i use to predict an up or down?

3. Where can i get the data to predict stocks which are on this app?
