How many trades should I take a day?

This comes down to how much time you are spending a day, and what your deadline is to complete the nurturing programme. 

You have a total of 50 demo trades to take in the nurturing programme.

If you are planning to complete the nurturing programme in 10 days, you must be taking at least 5 demo trades a day. (Not including the weekends, as the markets are closed.)
