The candle stick analysis were first used by Japanese for rice trading during the early 19th centuries. Now the intra day traders and short term(less than a week) traders are using this analysis.
We should use day candles and not the intraday candles. Day candles for period of a month or two can be used. Short term trends can be analysed using this.
The various types of candle stick patterns are
1. Engulfing
2. Piercing
3. Doji
4. Hammer and Hanging man.
