The market is constantly changing.
The ability to be able to manually read, interpret and act in ever changing market conditions is essential to becoming a successful trader over the long term. Automatic trading robots and "expert advisor" algorithms are programmed and optimized for past market activity.
While they often perform reasonably in the short term, you could be left unprepared to tackle an ever-changing market environment in the medium to long term. Despite your short term success, these tools will not (and by definition, cannot) create financial independence.
If you don't have the will, time or patience to speculate in the markets, we suggest a passive approach to investing using Strategy 1 at Infinite Prosperity.
