Just curious since the last discussion I had was about gambling vs trading. I know trading can seem to be a bit of a gamble as well, but I see it a little bit like poker. It's a combination of math and psychology. Maybe not the same ratio though, just generalizing 
Actually they are not the same. Maybe in some aspects there are some similarities but still, there's a big difference between the two. Both of them are risky, especially in gambling. When you do trading, you should have a knowledge on how trading works in order for you to earn money. Setting your target price would be a big help for you to earn. While in gambling, I think you just have to learn on how the game works. Sometimes, even we really know the game we cannot assure our victory. Sometimes it depends it on our luck.
