I have lost money both from CSE & Forex. I have wasted around 2 years studding various strategies & applying them but non of them helped me out & finally found my own way to succeed in forex after back testing the MT4 chart manually for 2-3 years period but it was also not successful after Brexit.
You will not understand Forex till you loss all what you have
BTW there are some cunning brokers who don't pay if you win a considerable amount of money pointing out different reasons, but if your winning is less than 500 or 1000, they will happily pay till you lost your original deposit+what you earn from them
