Candlestick Patterns Explained: What They Show and How to Test Them
What engulfing bars, pin bars, inside bars and dojis show, why context beats the pattern, and how to test candles before a prop firm challenge.
A candlestick pattern is a short description of how buyers and sellers moved price over one or a few bars. On its own a pattern tells you little. At a level that matters, it can give you a clear entry and a clear stop. This guide covers candle anatomy, four common patterns with precise definitions, why context does most of the work, and how to test patterns honestly.
Key takeaways
- Every candle shows four prices: open, high, low and close. Patterns are ways of reading them.
- The same pattern means different things at support, in the middle of a range, or during news.
- Write exact definitions before testing, such as a lower wick at least twice the body.
- Judge a pattern by its results in your own tests, not by claims about how often it works.
What does a candle actually show?
Each candle covers a fixed period, such as 15 minutes or one day. The body runs from the open to the close. The wicks, also called shadows, show the high and low beyond the body. A close above the open is usually drawn green or white, and a close below it red or black.
Two practical points matter. First, the close is the most important price, because it is where the period’s contest ended. Second, candles depend on when the period starts. In forex, daily candles usually close at 5pm New York time. Some platforms use a different server time and show a small extra candle on Sunday. Futures daily bars change shape if your chart uses only the 9:30am to 4pm New York cash session instead of the full Globex session. Check your settings so the candles you trade match the ones you test.
Four common patterns, defined
Definitions vary between books and platforms. The versions below are common and precise enough to test. Each describes the bullish form; the bearish form is the mirror image.
Engulfing bar
A bullish engulfing bar follows a down candle, and its body covers the whole body of that candle. Buyers took back the prior period’s loss and more. Some traders also require it to trade below the prior candle’s low first, which shows sellers were tried and failed.
Pin bar or hammer
A pin bar has a long wick on one side and a small body at the other end. A bullish pin bar is often called a hammer. A common definition: the lower wick is at least twice the body, and the close is in the top third of the range. Price was pushed down and rejected within the same period.
Inside bar
An inside bar has a high below the previous candle’s high and a low above its low. It shows a pause, with the range contracting. Traders usually trade a break of the outer candle, called the mother bar, in either direction.
Doji
A doji opens and closes at or very near the same price. One common threshold is a body smaller than 10% of the candle’s range. It shows indecision. A doji is rarely a signal by itself. At a level after a strong move, it tells you the push has at least paused.
Why context matters more than the pattern
A hammer in the middle of a range, where nothing is being defended, is just a candle with a long wick. The same hammer at a daily support zone, after a pullback in an uptrend, is worth a look. Context turns a shape into a trade idea. Check these before you act:
- Location: is the candle at a level you drew in advance, such as the prior day low?
- Trend: does the pattern point with the higher timeframe trend or against it?
- Size: compare the candle’s range with the ATR. A tiny pattern in a quiet market and a huge one after news are different events.
- Time: a pattern in thin hours means less than one formed in the London and New York overlap.
- News: candles printed around releases like US CPI or Nonfarm Payrolls reflect a burst of orders, not a settled shift.
A practical approach is to decide where you want to trade first, using levels from support and resistance. Then use the candle only as the trigger.
Worked example: a hammer at the prior day low
Example figures, Micro S&P 500 (MES), 5 minute chart. The prior day low is 5,000.00. A candle opens at 5,007.50, trades down to 5,000.00, up to 5,010.00 and closes at 5,009.00.
- Range: 5,010.00 minus 5,000.00 = 10 points. Body: 5,009.00 minus 5,007.50 = 1.5 points.
- Lower wick: 5,007.50 minus 5,000.00 = 7.5 points, five times the body.
- The top third of the range starts at 5,006.67, and the close is above it. The candle qualifies as a hammer.
- Entry: a buy stop one tick above the high, at 5,010.25. Stop: one tick below the low, at 4,999.75. Risk: 10.5 points.
- Loss per MES contract: 10.5 × $5 = $52.50. With $150 of risk per trade, 2 contracts risk $105. Three would risk $157.50, over budget.
- Target at 2 times risk: 21 points above entry, at 5,031.25.
The same trade on one ES contract risks 10.5 × $50 = $525, far more than the plan allows. That is why many challenge traders use micros for candle entries with wide stops. See micro vs mini futures for the full comparison.
How to test candlestick patterns
Be wary of published success rates for patterns. Results depend on market, timeframe, definition, costs and period, so someone else’s number may not apply to you. Run your own test.
- Write the definition in numbers, as in the hammer example, so two people would mark the same candles.
- Fix entry, stop, target and time exit before you look at any results.
- Mark every candle that qualifies in the test period, not just the ones that look good.
- Split results by context: at a level or not, with the trend or against it, and by session.
- Compare with a baseline: the same entry rules at the same levels without the pattern.
- Include spread, commission and one tick of slippage on stop orders.
The baseline step is the one most traders skip. It is also the one that tells you whether the candle adds anything. If entries at the level do just as well without the pattern, drop the pattern and keep the level. Log each trade with a pattern tag in the free journal.
How this fits prop firm rules
Candle entries meet prop firm rules in a few places:
- Daily loss limit: patterns with long wicks need wide stops, so size down to keep each loss a small slice of the daily limit.
- News rules: the biggest candles of the week often print around high impact releases, and many firms restrict trading in a window around them.
- Trailing drawdown: waiting for a candle close keeps entries selective, which helps avoid the overtrading that eats drawdown room.
- Consistency rules: a pattern you trade only a few times a month can leave profit bunched into one or two days.

Questions traders ask
Which candlestick pattern is the most reliable?
None is reliable on its own. How a pattern performs depends on location, market, timeframe and your exact rules, so test the ones you plan to trade.
Should I wait for the candle to close?
Yes, if your rules are built on closed candles. A hammer halfway through its period can still close as a large red candle. An early entry is a different setup from the one you tested.
Do candlestick patterns work the same in forex and futures?
The same shapes appear in both. Daily candles differ with session times and platform settings, so test on the same data and chart settings you will trade with.
Trading carries a high risk of loss. Most prop firm accounts are simulated, and the trade above uses example figures, not real results. Nothing here is financial advice.
