Steven Nison introduced candlesticks to the Western world with his book “Japanese Candlestick Charting Techniques”.
Candlesticks have become a staple of every trading platform and charting program for literally every financial trading vehicle.
A candlestick chart is simply a chart composed of individual candles, which traders use to understand price action.
Candlestick price action involves pinpointing where the price opened for a period, where the price closed for a period, as well as the price highs and lows for a specific period
A candlestick chart is also plotted with 4 share price data (i.e., open, high, low, and close) like a bar chart.
A candlestick charting technique was developed by Japanese commodity traders and they are usually called Japanese Candlesticks.
