This is what I do at work instead of what I'm supposed to be doing.

Is this good?
Am I getting lucky?
How can I improve my profits?
Or cut my losses?
Should I diversify more?
How can I improve?

Paper trading is a good way to get an idea how things work.

The challenge is that these trades may not have been executed because only a live market can determine the price.

Next, you have to add up how big is this portfolio? Do you have these assets, and then there is the question of margin.

I did this for a number of years before trading a single dollar. It helped, but there is a big difference to paper and real money, and real time.
