<<Look at what I am planning to do: Buy 500 shares and hold them until I have a profit of between 3 to 10 shares. Then sell lets say 495 shares to recoup my original cost of the 500 shares. I would have 5 shares over the rest of my lifetime or until cashed out that pay me dividends or increase (also decrease) in value.>>
What do you do if it goes the other way.
Say you buy 500 shares and hold them until you have a loss of 10 shares.
