If I go to Walmart and buy a bike for $259.99. I can decide to sell this for any price I want thereafter? Even $100,000,000,000.00 if I wanted? (Of course, whether someone buys is a different thing.)
If I buy stocks or commodities in the market, can I decide what to sell them for? People say that the "value" of something depends on the demand--but when people own things they reserve the right to sell them for any price they want--the can even give them away freely at their discretion.
Can I do the same with publicly traded stocks? If I buy a stock, how much can I sell it back for? What the market says or whatever I feel like? In other words, does the market have control over sale numbers or do I?
