Unarguably, Cent account is something that I truly need! Back when I was using my first broker (this one is the 2nd), I used demo account and I didn't have feeling of real trading, I understood that it was the demo environment where money was unreal.
Their cent account is a real one, where balance is calculated into cents. I deposited $100 and got 10000 cents for trading. It helps me to test various strategies, now I continue working n the strategy that will have the coolest P/L. Everything is fine, leverage is suitable for me, I don't abuse it beccause I own that it bears certain risks.
