How Markets Work
Share prices are determined by supply and demand of real players, and players are most likely motivated to invest in a particular stock because it is paying good dividends. As a result, attractive dividend payouts usually result in higher share price.
On the contrary, stock which does not pay dividends will not attract much attention (hence has lower share price) because traders would be better off by investing in other stocks instead of sitting on this "dead" duck.
Entering the market
While you are free to buy any shares listed in the stock exchange, it is recommended that you pick stocks which you have at least some interest/knowledge.
For example, if you don't know anything about Formula 1, it is unlikely you can make an educated guess who is going to win (and pays dividend).
Offer To Buy
When share price is higher than what you believe it should be, you may submit a buy-listing at your desired asking price, once someone is willing to sell at your asking price, shares will be sold to you.
Offer To Sell
When share price is lower than what you believe it should be, you may submit a sell-listing at your desired asking price, once someone is willing to buy at your asking price, shares will be bought from you.
All transactions attract a Brokerage Fee of 1%.
Normal traders are restricted to a maximum shareholding of 20,000 shares per stock.
Each market has its own way of determining if dividends will be paid and how much will be paid.
