Japanese candlestick patterns are more intuitive than classic barcharts. You can learn to identify them and take a quiz to test your knowledge. Also there is a Japanese candlestick poster available on Ebay.
What is that thing? It is a tool for analysis? Testing knowledge is somehow great, but it is not useful for the experienced traders.
The Japanese candlestick actually appears to be superficially very similar to the different error bars but they are actually not in any way related.
MrPolarZero, The candlestick are similar to bar charts that we normally use. However, candlestick is much more powerful in reading charts and give insightful predictive power in trading.
