Divergence
Price makes a new extreme and the oscillator does not. This is the only factor allowed to argue with the trend, and its weight is higher than the rest (2 against 1 for most).
Divergence does not say "it will turn now" but "the move is losing strength". The difference matters: a divergence can persist for a long time.
Pin bar and rejection at the edge
A candle with a long wick at the edge of a range: price went beyond the level and was rejected. The wick factor in the set is exactly this.
A streak of same-coloured candles
Five or six candles in a row in one direction are statistically more often followed by a pullback. The factor is a reversal one and is more useful in a range than in a trend.
FVG — fair value gap
A stretch price covered so quickly that a "hole" was left between the wicks of neighbouring candles. Such gaps are often filled later, and that is used as a reference.
Order block
The last opposite candle before a strong move — treated as a zone where large interest sat. The factor triggers when price returns to it.
Sweep — a liquidity grab
Price moves beyond an obvious level (yesterday's high, the edge of a range), collects stops and comes back. A sign that the breakout was false.
Fibonacci levels
A bounce off the 61.8 % retracement counts as a separate factor. It works not because the number is magical but because many people place orders at those levels.
