@chitta100000, Hello sir, first you must know how to read candlestick pattern, in order you know what is doji, bullish and bearish engulfing etc... I like to use in this way. The gray line is something like a trendline, you can see how the candlestick is stand above or below the gray line and if the blue line is above the candle bias the price could head to downside. Good Luck =D
