Technical analysis reads what price and volume have already done, and it starts with the candle. Each candle records one session's open, high, low and close, and which side held control at the end. A candlestick pattern is a short run of candles that marks where that control may be changing.
A pattern is not a signal on its own. Traders read it against what surrounds it: moving averages, RSI, MACD, volume and the readings built on it (On-Balance Volume, the Accumulation/Distribution line, Volume Spread Analysis, volume profile and anchored VWAP), Fibonacci retracements, ATR, trend channels, trading ranges, and multi-timeframe analysis (the weekly chart behind a daily setup).
Below are all 32 patterns the 42Fibonacci screener detects, the context guides that cover each indicator, cheat sheets for checking a chart quickly, and how to read a candlestick chart.
Long wick, full reclaim
A long tail, read twice
Upper probe after a selloff
Deep low, closed at the high
Opens at the low, never trades below
Open = close. A stalemate.
Wide range, flat close
Small body, wicks both sides
Small body, a huge range
One price, almost no trading
One body fully engulfs the other
No lower open, then a takeover
Two shaved candles, a gap between
A bearish shape, a bullish name
Small body inside a big move
Red, but a higher close
Gaps down, rallies past midpoint
A big rally back to even
Same price, two sessions
Same close, not same low
A gapped doji, still unfinished
A harami, then a close above the first open
An engulfing, then a higher close
Three candles: down → pause → up
A new low, held the next day
Three green closes in a row
Read the lows, not the color
A doji stranded by two gaps
Three doji, one failed push
