What is actually happening?
A lower wick records traded prices below the body within an interval. Ending near the upper part of the range describes where the close occurred, not whose orders caused it. Different intrabar paths can produce the same four OHLC values.
Guided example · Synthetic pin-bar measurement and counterexample
Measure the wick before naming a signal
A large lower wick describes price travel. Put that shape beside a fixed reference.
Restart & example assumptions
Authored synthetic observations, shown in sequence. Every comparison uses only the revealed data. This is a worked learning example, not live prices, broker execution or a profitability backtest. Follow the article’s exact definitions; measurements and pattern names alone do not authorize a trade.
For charts: tap a candle or swing to inspect it; drag horizontally to browse; wheel or +/− to zoom; arrow keys to inspect; Home to restore the step view.
Make the conditions explicit.
State the interval, price source and numerical shape definition. Compare a candle near an earlier low with the same shape inside an overlapping range.
For the reading exercise, calculate body, both wicks and close location. Then pre-mark the nearby reference before revealing later candles.
A later close below a fixed reference contradicts a stated hold-above interpretation. Do not move the reference or change the wick ratio after failure.
The quoted rules are illustrative research specifications. Parameters are not recommendations and have not been presented as profitable backtest results.
What can this cost?
An entry above the body and an exit under the low can imply a much larger distance than the body suggests. Include actual fill and costs before considering size.
How the idea can fail.
The same pin-shaped candle may be followed by a close below 94. The original shape remains valid even though the subsequent hold-above hypothesis failed.
Practical habit
Use “a return into the close,” not “a bank finished accumulating.” Label causal explanations as hypotheses requiring other evidence.
Go one level deeper
Freeze any ratio threshold and location rule before evaluating an untouched sample. Do not select only textbook winners.
