The CTX exchange

CTX is a game stock that only exists inside ChartTrainer. You trade it with coins on a real order book.

The price moves on its own from a market simulation (calm and busy stretches, the odd jump like news), and simulated traders keep the book full and trading around the clock. Your orders sit in the same book: a limit order waits at your price and fills when someone trades against it, a market order takes the best prices available right now. Big orders move the price.

Buying holds your coins, selling needs shares you own (no short selling). Up to 10 open orders and 10,000 shares per order. Limit prices must be within 50% of the last price.

It's practice for reading an order book with something at stake, not an investment. CTX and coins have no cash value.
