The Theory of Stock Exchange Speculation. English-only reading by default; switch among English, Chinese, and Spanish, or compare languages side by side.

For readers interested in bid-ask spreads, dealer economics, liquidity, transaction costs, volatile securities, and the structural disadvantage faced by short-term speculators.
