The stock market in Kingdom Of Riches acts just like a real stock market. You have 5000 tickets per day which resets at midnight gametime. These tickets count to every stock you sell or buy.
Once you have bought some stock. You watch to see when the best time to sell is. The main objective is to sell your stock to gain a profit. Every hour the price of a single stock for each company will change. Sometimes it will rise, sometimes it will lower. You can sell your stock at any time, but be warned that while you can gain money, you can also lose it quite as easily.
