What is a realistic ROI monthly for an experienced Forex trader?

How much % gains are you making a month on your account?

How long have you been trading for?

Have lost a LOT of money in the 2 years 4 months I’ve been in forex. Hit a lucky streak lately. Put up 3,000 in April. 11, 2019. Profited so far almost $17,000, around 560% by my last estimate. Probably not sustainable though.
