It takes a pretty long time for one to actually become a very good trader personally it took me long like two to three years to become a moderate trader . One has to be really persistent and patient with the and trading process to become a profitable trader.
I think that there is no exact time interval after which it will be possible to say that a beginner has become a real trader. Everything is individual, so, for example, it took you 2 years to become a moderate trader, and another will not be enough for 5 years to achieve the same result.
