Feasibility of using long term pattern on short term investments
There are Patterns inside of Patterns. You will see short term patterns (flags / pennants) inside of long term patterns (trend lines, channels) and typically you want to trade those short term patterns in line with the direction of the long term pattern.  Take a look at the attached chart of GPN. I would like to recommend two excellent books on Chart Patterns. Richard W. Schabacker book he wrote in the 1930's. It is the basis for modern technical pattern analysis.  Technical Analysis and Stock Market Profits  Peter Brandt Diary of a Professional Commodity Trader. He takes you through analysis and trades.
