Plotting Charts. http://www.financial-spread-betting.com/course/technical-analysis.html In the early days I used to update my own charts day by day on the trading desk. Plotting charts is useful to understand the price action and psychology in technical terms. Drawing the open, high, low, close is very good. Once you get the hang of it, obviously doing charts by hand is likely to be restrictive so this is the time to start looking at software programmes to generate the charts for you.
