I would want to know from others here if truly their account balance determines what they would profit as a trader.. but then I have to think twice and said that our balance is not a product of our profit rather this is a factor of our in depth knowledge and understanding towards trading. You can have a sizable account balance but if you don't know what you are doing you would still end up losing them all so you should be able to know what you are doing.
For you to profits as a trader you must learn to work on your emotions, which includes risk management and knowing the right time to enter trade and when not to enter trade. In fact you must also understand your candle reading, which includes technical and fundamental analysis in other to understand how the market is moving and this is not all, you must also learn to control your greed index otherwise you could lose after some good profits from the previous trades. However, having a sizable account balance doesn't really attributes to how successful you could become if you don't have the right knowledge of trading.
Depends, it depends on how you use it. A small balance means that you are not going to profit enough to make sense. Someone with a 100 dollar balance, can't make that much profit, I mean you can make 10% per day, and you would still have just 10 dollars per day, not a bad one and if you put it on top and repeat and keep doing that then yeah you will get rich eventually, but let's face it, nobody makes 10% a day everyday, so a small balance means small return, not enough to care.
But, if you have a big balance, there is no guarantee of profit neither, and you may end up losing money as well. So you are not going to get anything great out of this, the results may not be all that great for you in either case.
