Take a break from real trading, paper-trade for a while & save money in the meanwhile, I think your capital was just too low & the length of the challenge too short. Go through the following thread, where this trader patiently traded risking 500 per trade & turned 5,000 into 20,000 in several months, which is a great 300% ROI, though unfortunately, he lost his discipline later on but nonetheless, the point being that maybe you should save 5,000-10,000 & then give it a go with a well-tested profitable strategy WITH GOOD MONEY-MANAGEMENT because no matter how good your strategy is, if you don't have money management, then you're just waiting for a disaster to happen -
