Autocorrelation is a mathematical representation of the degree of similarity between a given time series and a lagged version of itself over successive time intervals. It is the same as calculating the correlation between two different time series, except autocorrelation uses the same time series twice: once in its original form and once lagged one or more time periods.

The quantity theory of money is a theory that variations in price relate to variations in the money supply. The most common version, sometimes called the neo-quantity theory or Fisherian theory, suggests there is a mechanical and fixed proportional relationship between changes in the money supply and the general price level. This popular, albeit controversial, formulation of the quantity theory of money is based upon an equation by American economist Irving Fisher.
The Hull-White model is a single-factor interest model used to price derivatives. The Hull-White model assumes that short rates have a normal distribution and that the short rates are subject to mean reversion. Volatility is likely to be low when short rates are near zero, which is reflected in a larger mean reversion in the model. The Hull-White model extends the Vasicek Model and Cox-Ingersoll-Ross (CIR) model.
Unlimited tax bonds are a type of municipal bond backed by the full faith and commitment of the issuer, which is generally a city or municipality, to raise taxes, without limit, to service the debt until it is repaid. Because of this feature, unlimited tax bonds may have higher credit ratings and offer lower yields than other comparable municipal bonds of the same maturity.
Real-time is when a system relays information to a user at a speed that is near-instantaneous or has a short delay from when the event occurred.

Tenkan-Sen, or Conversion Line, is the mid-point of the highest and lowest prices of an asset over the last nine periods.

Ichimoku Kinko Hyo roughly means one look equilibrium chart, and is commonly called the Ichimoku Cloud indicator.
