You have to understand as a friend to traders that even in times when big wins are celebrated, it is not still a time to ask them to help you with money for your needs with the thought that they are in profit, because if you do you will get yourself disappointed nine times in ten chances.
Work for your own money, nobody owes you anything.
Money is hard to earn nowadays. We all know that trading is not an easy way.if you have earned in trading but your friend will be the one to enjoyed or used it, your sacrifices are all for nothing. There are friends that are fast when lending but if you are to charge them, they are the one who is angry.
But of course if your family is the one that lends, especially your parents I think it OK to lend since they are your family. They are the one you beg if have nothing else left.
