I am not active in trading at all so the use of paper trading will be useful for me to provide a platform for me to check my own viewpoint to see the results.

I think it is always good to have a plan in mind. If the plan is not in my favour, I will need to learn how to revisit it and look back at my thesis. I will do the necessary to at least check my profit and loss margin. Fail to plan , plan to fail...

How to ride the waves effectively depends on individuals. For me, I just watch and learn first as it is painful to look at losses. Will we ever win the algorithms that's my more important question than talking about buidling a portfolio?

As the saying goes "an apple a day keeps the doctor away", I think it will be apt even for the investors investing in the stock. No need to constantly be fearful of bad drastic dips for this company.
