Technical Analysis…a Brief Background Technical analysis is simply the study of prices as reflected on price charts. Technical analysis assumes that current prices should represent all known information about the markets. Prices not only reflect intrinsic facts, they also represent human emotion and the pervasive mass psychology and mood of the moment. Prices are, in the end, a function of supply and demand. However, on a moment to moment basis, human emotions…fear, greed, panic, hysteria, elation, etc. also dramatically effect prices. Markets may move based upon people’s expectations, not necessarily facts. A market "technician" attempts to disregard the emotional component of trading by making his decisions based upon chart formations, assuming that prices reflect both facts and emotion. Standard bar charts are commonly used to convey price activity into an easily readable chart. Usually four elements make up a bar chart, the Open, High, Low, and Close for the trading session/time period. A price bar can represent any time frame the user wishes, from 1 minute to 1 month. The total vertical length/height of the bar represents the entire trading range for the period. The top of the bar represents the highest price of the period, and the bottom of the bar represents the lowest price of the period. The Open is represented by a small dash to the left of the bar, and the Close for the session is a small dash to the right of the bar. Below is a standard bar chart example.
