My brother is doing online share trading. (Intra trading) Yesterday was a good day for him as crude oil prices have come down, it had a great impact over some company's shares getting higher and higher yesterday, but my Brother was not feeling well and he within 5 minutes of purchase, took 50% of what he invested and signed off. - With this, yesterday we
earned $ 50
Then he saw another company share price getting extremely down and he thought that the company share price can't go more down but only up. So, he bought them. But the company shares kept on going down. and because, of that, he had to face a loss of $75 - Resulted in $25 loss yesterday
The thing is, current gone in between and since he wasn't feeling well, he wasn't go out to browsing and finish that trading, if he was well, then he would haven't let it down to loss. He's that much experienced. He planned perfect but current made a deep impact.

Today have to take all those money.
