If you are professional then you must know to trade under pressure and nervousness doesn't help to make profits. And to double capital within 2 months is not possible for most of the traders! Because it needs luck to make a good profit in this bear market. So, try to concentrate on one thing, do normal trades and do other things to make money. Best of luck.
Trading itself is a stressful activity especially if you as a trader has target how much profit to achieved, I mean with the target it will be very possible to focus more on that target rather than to trading it self, and I do not believe that in trading luck plays a role because in trading there is a section analyzing the market whether to go up or down. It is quite possible to double your money in two months and vice versa especially if you do it without adequate knowledge.
