1829 vs 1830 stock market

The 1829-style stock market is also simple and interesting, but seems less useful for this project. The market is linear rather than rectangular, and stocks can only rise and fall by various steps. Some of the 1829 markets are more interesting than others (eg 1860’s), but in general they are less expressive than the 1830 model. Thus I’m sticking with the 1830 approach for the nonce.
