Buy Low, Sell High

Background
This Storyline Level 3 interaction was created for junior to senior high students to teach the basics about buying and selling stocks. Detailed logic manages calculations and button availability to ensure the player can only buy and sell stocks based on their portfolio value. Each trade costs $1, but isn't removed until players commit their trades for the day. Players use the news and tips to determine which stocks to buy and sell, then see how well they did the "next day".

Game play

• The game spans five trading days.
• The player buys and sells stocks by using the spinner buttons.
