aasaan jab ham apane niyamon ka paalan na karen, jab ham badhate nukasaan ko dekhate hue bekaar baithate hain aur na roken trigar karane aur apane tredon ko band karane ke lie na karen to yah hamaare khaate ko udaane jaise kharaab nateeje par le jaega.
I think it's because of my friend's greed. In one scenario,
a very greedy person will tend to multiply or greatly increase the number of Lot and Risk traded in one position when he or she earns a profit line. On the other hand, some will also increase their lot size when
losing because they want to get the return / revenge of all the losing positions.
