Candle Stick
If you analyze last three days trading with candlestick it has formed three big white candles. This is very similar to three whit soldiers pattern. This is generally considered bullish, as prices closed significantly higher than they opened. If the candle appears when prices are "low," it may be the first sign of a bottom. If it occurs when prices are rebounding off of a support area (e.g., a moving average, trendline, or retracement level), the long white candle adds credibility to the support. Similarly, if the candle appears during a breakout above a resistance area, the long white candle adds credibility to the breakout.
