Million Dollar Traders

Accidentally stumbled upon some kind of vidos… about “type of traders”))
I am, he called fluently… but by “ihnemu” I don't fucking understand… That's why, you are not difficult, who could translate, explain a few questions:

0) What is this all about??) Is it a prop or cho. Why did they collect some rabble.. grandfathers, dibs, heifers, black people.. cunt.. What are these losers?
1) Fuck they call on the phone and buy something there, they have that, no terminals?)
2) What kind of pieces of paper they compose there and refer to the main thing and most importantly why? Report their trades?
3) What's in the 3rd part in the end? For which the hysteric was ordered out?
