Account alomost doubled for about 1 month. Picking good stock matters a lot!
Could you supply some more information about your system, like:
1) To what extent is it mechanical/discretionary?
2) Are there any past performance data, real or hypothetical?
3) What is the estimated maximum drawdown?
4) Are you trading it yourself in your own account and if so since when?
5) What is your trading background?
The more information you can supply the better.
At this point nobody can tell if the performance is based on merit or just luck.
