How Much Can A Day Trader Make A Day?

When I just started trading the right way ( i spent a long time doing the wrong thing and losing money)  I used to primarily Day Trade and at my very best I was making an average of $3500 per day when I was firing on all cylinders.  

But, theoretically there is no limit to how much a Day Trader can make on a daily basis. It is all about how good your trading strategy is, how well you execute the strategy, how much risk you are taking.
