This is common, so don't feel like you've been suckered.
I personally don't think it's mere coincidence that the majority of retail forex traders who are grossly underfunded are also under-educated, yet it's RIDICULOUSLY simple to set up an account and be trading with 50-1000x margin within minutes...
+1 to everything MG99 said.
You need to stop trading, and educate yourself on the markets, human psychology and risk management.
I can tell you one thing, and this is my opinion. When you claim "I've been studying forex a lot"... then follow it up with the fact that you made 600% (on $100), lost it all basically, and now are upset, that you're simply very new to the game and are making necessary mistakes.
Trading like a professional is absolutely no different than any other skill which one attempts to master.
I don't know where you're from..but think of it like this: The professional traders out there- do you think they were up and running in 6 months, making 100's of thousands of dollars with near-perfect execution?
Would you be able to pick up a baseball bat, and go up against a professional-level pitcher who could throw 98MPH fastballs inches from your face? Would you be confident holding that bat?
How much confidence do you have in yourself? Are you seeking validation through trading?
Look, everyone pays the price in the beginning- that 's why the turnover is so grossly massive and why retail brokers make so much money.
You need to understand what and who you are up against. If you don't know your competition, how do you expect to avoid defeat.
Find a mentor.
Dig and dig and dig and dig youtube for videos.
Don't put too much value in demo trading- it's nothing like live trading. Demo trading should only really be used to test a platform and a get feel for the markets in the beginning.

Cut your losses. Always cut your losses. It's not about how much you make- it's about how much you can actually keep @ the end of the hour/day/week/month/year.
