So I went through boot camp - code is straight forward and it is easy to understand. 

Now I am completely lost and have no clue what to do. What's the next step?

Looking to create a bot, that will find momentum stocks, identify patterns, apply “buying high and selling higher" strategy…

Algorithm Lab looks super confusing as well. Not sure how much I have to pay if I implement these in my code. Is it per query, per dollar amount, how the … it all works?

Is there a way to implement Lightspeed?

Everything looks so confusing at this point, are there any books, material, examples to read?
