In the past. I wrote an algorithm trader for forex. it worked brilliantly while testing with $100 real dollars. When we switched to $10,000, it lost every trade. Turned out that the broker was stealing from us on every trade. Moral of the story is be careful who you do business with. Thieves are attracted to the finance game and they go all the way to the top.
