Yes, making 30% daily is realistic expectation. But I think that making 100% daily is also realistic. I am saying this on the basis of some calculation. Example: if I am investing $10, if I am using the leverage of 1:500, then i can trade upto 5000 bucks. So isn't it quite easy to earn just 20 bucks a day.? Yes, there is risk. But if there is confidence and knowledge about trade, then profit can be made. If not then we will even make loss at simple trade. I have done this sometimes.
You think that easy. Well, if you have to trade with leverage then you will have to be in when they maket will be going up and up because just a bit back wards can drain down the money because when you are trading with leverage you positions are quite exposed to risk and when it happens it happens fast like a lighten.
