Candles
This type of chart is also commonly called Candlestick or Japanese candles. They were first used in Japan in the 18th century to predict the price of rice. At that time, there were already futures contracts that were intended to unite the needs of producers with traders. The inventor, Munehisa Homma, earned a fortune thanks to this method and used war terms used in battle to provide terms for technical representations. The method arrived in Europe in 1989 thanks to Steve Nison who published various rules in his famous book Japanese Candlestick Charting Techniques. Today it is the most used graphic display method by traders.
