How to read this

Everything here is in R, the setup's own risk. 1R is the distance from the entry (the pattern's closing price) to where it would be proven wrong — its lowest low over the 2 bars that form it. So "offered 2R" means price ran twice that distance in your favor at some point before the stop. It does not assume you took profit there: a target is a strategy choice.

Room offered (≥ 1R)

45.8%

Too few to trust

Offered at least 1× its risk before the stop, vs 41.8% for a random long entry (+4.0 pts).

Move size vs normal

2.56×

Realized range over the next 20 bars vs a random bar. Precedes a bigger move.

Typical room (20-bar)

1.21R

Average run in favor (capped at 3R), vs 1.09R for a random long entry.

Summary

Offered ≥1R 45.8% of the time vs 41.8% for a random long entry. The 4.0-point gap is no bigger than the ±19.7-point margin of error you would get by chance from 24 occurrences. Not a reliable edge.

Room offered, this setup vs a random long entry

Only 24 occurrences. The breakdown below is shown in full, but a sample this small is anecdotal, a hint, not a measured edge. That is usually a limit of available history, not a flaw in the pattern. For a firmer read, try a lower timeframe or a more active instrument.

A bullish piercing line is a two-candle bottom where buyers grab back most of a loss. A long down candle comes first. The next candle opens lower, below the first candle’s range, then rallies hard and closes back above the midpoint of that down candle’s body. Sellers had the open, but buyers took the rest of the session and pierced deep into the prior loss.

The piercing line is one of the classical reversal patterns Steve Nison details in Japanese Candlestick Charting Techniques (1991), the softer cousin of the bullish engulfing.

How to spot it

  • The market is falling into the pattern.
  • The first candle is a down (red) candle that fits the decline.
  • The second candle opens lower, gapping below the first candle’s close.
  • It then closes up (green), above the midpoint of the first candle’s body.
  • Its close stays below the top of the first candle’s body, so it pierces but does not fully reclaim the loss.
  • The deeper the close into the first body, the stronger the signal.

The dashed box on the chart above marks the two candles on a real occurrence, with the decline before and the move after.

The psychology

The first candle keeps the slide going, and sellers end it firmly in front. The next session opens even lower, which is exactly what they want to see, and for a moment the decline looks set to deepen. Then the move turns. Buyers absorb the lower open and drive price all the way back up past the middle of the prior candle’s body.

What traders read here is a shift in who is willing to commit. The sellers got their lower open and could not hold it, while buyers showed up with enough size to claw back more than half of a full down candle in a single session. They did not erase the whole loss, so the handover is not complete, but the deeper that close cuts into the first body, the more it looks like control is changing hands. The lower open also leaves late sellers sitting on a poor entry, and their buying to get out can feed the bounce.

Whether that turn carries through is the question the figures below take up.

Does it actually work?

A pattern is a setup, not a trade, so the honest question is not “did it win” but “how much room did it tend to offer before it was proven wrong.” The tabs below answer that across five futures markets (Nasdaq, S&P 500, gold, crude oil, natural gas) and seven timeframes from one minute to one day.

For each occurrence we measure the room the move offered in units of the pattern’s own risk, then set it against what a random entry on the same market would have done. When the pattern offers more room more often than chance, that shows up as a real edge. When it does not, the page says so plainly.

Read it with the sample size in view. On the faster timeframes a pattern can fire thousands of times, enough to trust. On the daily chart it is far rarer, so treat those numbers as a hint rather than a verdict. Thin samples are flagged for you on the page.

How we measured it

  • Entry is the close of the final candle of the pattern.
  • One unit of risk, 1R, is the distance from that close down to the pattern’s invalidation point: the lowest low of the two candles that form it. If price trades through there, the setup is wrong.
  • We then follow the next 20 bars and record how far price ran in your favor, in multiples of that risk, before the stop was hit.
  • Every figure is set against a random entry on the same market and timeframe, so the market’s own drift is accounted for.
  • No profit target and no position sizing. Where you take profit is a strategy choice; this measures only the room the pattern tends to give.

What this page does not cover

  • Volume on the pattern’s candles.
  • Whether the pattern forms at a meaningful support level.
  • Pairing it with a trend filter or a confirming signal.
  • A profit target or position sizing. We use the pattern’s own invalidation point as the stop to define risk, but where you take profit, and how much you put on, are strategy decisions this page leaves to you.
