Why can’t anyone submit a stock sell order with a price range?  In other words with a maximum price AND a minimum price so you maximize your profit and minimize your loss?  Why do we have to hope it will go up and never go down?

Why do we have to use a 100 year old process that is susceptible to flash crashes and flash freezes?

Benefits of a selling price range include less risk.  A flash crash would be averted because free-falling stock prices would not happen since everyone would sell out at the lower price before a crash occurred.

But better yet, what if you allowed the maximum price to rise with the stock price?  The result is more profit if your stock rises even further.

And what if this new system works for shorting stocks as well as buying stocks?

There is a patent pending process called the Low High Trailing Execution Stock Orders System.

Time to enter the next century.
