I built a live Steam player count tracker (flopathon.cc) and added a virtual stock market on top of it.
Stock prices update hourly using a formula based on deviation from the 7-day moving average of concurrent players. Sensitivity factor of 0.3 so a 10% deviation = ~3% price move. Floor at 1 FC.
The stock market is free to use. Users get 10,000 virtual FlopCoins, can buy/long or short any tracked game. 5% fee on shorts to prevent trivial shorting since most games naturally decline.
