That is one of toughest situation that I can imagine.
You've made two unforgivable mistakes which everyone should remember as if this whole story happened to them. The first one is taking a loan. The funniest thing here is that there are still many people who take a loan for trading after they heard some commercial or a friend of a frined who made a fortune in trading following some 'simple steps'. Such scammers are really good at affecting people's decisions and they get the money from naive idiots. I believe that quite the same thing happened to the author of this story and he/she definetely learned a lesson out of this. The loan should be taken for some adequate and well-calculated decision, like making a business with certain strickt and sensible business plan. The loans are suitable for those people who feel financially safe and who cn pay out their debts, but who don't want to invest their own money in order to remain safe with their budget.
The second mistake is the absense of money and risk management. Perhaps, this is the most important thing in trading because judging by author, it worked sometimes. if they calculated risks and the amount of the deal, they would probably even make the profits. If the strategy worked in 50%of cases with the risk ratio 1:2, the trading would be profitable. However, the guy became overconfident which led him to the total loss.
Don't repeat such mistakes!
