Volatility
Usually defined as the standard deviation of returns of an asset. Volatility generally refers to the magnitude of price movements in a specific asset. Large price movements are said to be more volatile and vice versa. Volatility has a major direct influence on option premium levels. When volatility is high, premiums increase (all other assumptions remaining the same). When volatility is low, premiums decline.
Volume

VWAP
VWAP - 'volume-weighted average price' - represents the total value of shares traded in a particular stock on a given day, divided by the total volume of shares traded in that stock on that day. Calculation techniques vary: some will use data from all markets or just the primary market and may or may not adjust for resubmits and other error corrections. VWAP is a method of pricing transactions and also a benchmark to measure the efficiency of institutional trading or the performance of traders themselves.
