If you happen to be an active trader or know people that trade actively, you will notice that traders do not easily give out money ( i.e lend out money) not because they don't have to give but because their capital is actively and most times always involved a trade.
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.
It does not implies to all the active traders as some of them are into lending business also and gain interest from that but it involves a element of risk that your capital is safe.But if your relative or friend is in great need and you have surplus funds aside from your investment purposes then you should help them.Active traders tries to secure their capital because they don't have idea of the market and if they incurr any loss or if the market crash situation arises they need to deposit funds to their wallet which they have set aside.So you can see it is personal choice of every trader that how he wants to trade in the market based on real time experience.You need to have fund management policy implemented very well which provides you with capital guaranteed plans.
