It is possible but you have to find the right entry point to do it and make sure you don’t get mixed signals. The capital you use on a demo account is probably different than 100$ …So if one of your trades go wrong…boom margin call… What i would really suggest is start with a 1000$ account if you have that cash. Trade 0.01 lots to 0.05 - With the right discipline and analysis you can make let’s say 2000$ in 2-3 months… From there you can use bigger lots 0.07- 0.10 and so on…Keep the same strategy and slightly increase the lots traded , this way you get the hang of it and with the right risk reward ratio you can pump up your account. It really depends also on what kind of trader you are, are you a swing trader? are you using all the macro tools and fundamentals to get you where you want? are you a scalper? are you using the right tools? . If you trade purely on fundamentals than you should really consider that sometimes the market oscillates when a breakout is about to happen. (thank that to algos) Remember in forex trading people buy the rumor and sell the fact. There are so many things that you need to keep in mind before entering a trade.
What i highly recommend is go back to the drawing board because all you do is gambling. You will probably hit the right spots a few times and you will think.Wow i am the best trader, you will use the same lots when you will have more money into your account, guess what will happen if market moves against you? Blow up your account!
I do not know what to say more to convince you to use a proper risk management, but i am telling this out of my own experience. I blew a lot of money on this and it felt good when i was riding the wave. But its the same as playing a slot machine, sometimes you win, but most of the times you blow your account.
