Simple answer, a profitable trading style.
Every single trading style has its critical weakness, and if you don't see any weakness in your style then you don't know how to trade it, this applies to even the best of the best traders at my firm, traders who make a million a year know exactly what's wrong with their style, that's how they can work around it.
Once you see the flaw in your trading style, you need to ask yourself whether this style is for you. You may not be a good bottom picker but you may be good at fading gaps, you may not be a good trader at fast and volatile stocks but you can handle second tier's, you may not have the discipline to be a scalper but you can hold on to your winner patiently riding out the whole trend, etc.
If you are not profitable, either your style is fundamentally wrong (99.99% of the styles directly taken from books), or it is not the right style for you, keep looking.
