 +======= Stocks Game Mechanics =======
  
 +
 +The Game Mechanics section of the manual details the internal formula used in the game's calculations.  This section of the manual uses pseudo-code and may not be 100% the same as the code in the game. 
 +
 +The Game Mechanics part of the manual is mainly designed to be a reference for the frequently asked question, "Why do I get this rating when I do X, Y, Z?!" Usually, this answer involves many different variables, which this section of the manual demonstrates. 
 +
 +**The game mechanics section of the manual shows [[https://idioms.thefreedictionary.com/seeing+how+the+sausage+gets+made|how the sausage gets made]]. So you really may want to avoid this portion of the manual if you enjoy the game.**
