CANDLES: WHAT ONE BAR ACTUALLY RECORDS

STAGE 3 — Reading Charts (on SPY) · Prerequisite: Stage 2 — Brokers, Accounts & Orders (the orders you will aim with these charts)
TL;DR
  • A candle compresses one period of trading into four prints: where it opened, the highest and lowest prices anyone actually got, and where it closed. The body is open-to-close; the wicks are the excursions that didn't hold.
  • Colour is one narrow fact: green means the period closed above its own open, red means below. It says nothing about yesterday — a green candle can sit inside a down day if the period opened with a gap down.
  • A candle never records the path between its prints, the reasons behind them, or what happens next. Reading more than that into one bar is the beginner's first chart mistake.

Four prints and nothing else: open, high, low, close. What a candle honestly records — and the three things it can never tell you. A candle is a game's final score with the furthest-ahead and furthest-behind markers attached: the score at kickoff (open), the best moment (high), the worst moment (low), and the final score (close). It tells you the game happened and how it ended. It does not tell you the order the middle events came in, who got injured, or who wins next week — and anyone selling you a single candle as a prediction is selling you the scoreboard as a crystal ball.

THE TAKEAWAYS

  • The four prints, on a real bar: SPY, Oct 9, 2026 — open 776.24, high 779.42, low 775.14, close 778.57. Body +2.33 (open to close), whole range 4.28. The wicks are what's left: 0.85 poked above the close, 1.10 dipped below the open. The graphic draws this candle life-size.
  • A wide body means one side controlled the period's start-to-finish; a tiny body with long wicks means the period travelled and came back. Feb 13, 2026: open 681.69, close 681.75 — a body of +0.06 — inside an 8.76 range, on the heaviest volume in this stage (96.3M shares). Enormous effort, no winner: a draw, drawn as a candle.
  • The opposite colour, same honesty: Oct 14, 2026 — open 774.92, close 769.60, a red body of −5.32 inside a 9.64 range. Then the gap: Oct 15 opened at 766.25, 3.35 below Oct 14's close. The empty space between the candles is the gap — prices nobody ever traded at, because the market was shut while the news moved.
  • What a candle cannot say: whether the high came before the low, how long price stayed anywhere, how many shares changed hands getting there (that's volume, Lesson 5), and — the one that matters — what the next candle does. Candles are records, not forecasts.
RUSTY’S RULE
Read a candle as a record, not a forecast: four prints, one period, no promises. Anyone who tells you a candle shape means price will do something next is selling certainty the bar doesn't contain.

WORKED EXAMPLE — STEP BY STEP

  1. Take the green one first — Oct 9, 2026, drawn large on the graphic. Start at the open, 776.24: the first print of the day. The day's trading reached as high as 779.42 (the top wick) and as low as 775.14 (the bottom wick), and the last print was 778.57. Four numbers, and the candle is fully decoded.
  2. Measure the parts: body = 778.57 − 776.24 = +2.33. Upper wick = 779.42 − 778.57 = 0.85 — buyers pushed 85 cents above where the day settled and couldn't hold it. Lower wick = 776.24 − 775.14 = 1.10. Range = 4.28 points of travel inside one day.
  3. Now the red one — Oct 14: open 774.92, close 769.60. Body −5.32, more than twice Oct 9's, inside a 9.64 range. Sellers controlled start-to-finish — but note the lower wick of 2.89 (769.60 close vs the 766.71 low): price fell further than it closed. Even the worst day of the month so far bought back its last 2.89 points.
  4. Now the draw — Feb 13, 2026: body +0.06, range 8.76, volume 96.3M shares (Lesson 5 returns to that number). Price swung nearly nine points and ended where it started. If one candle could ‘mean’ something, this is the one that proves the point: it means both sides showed up in force and neither won.
  5. Finish with the space between candles: Oct 14 closed 769.60; Oct 15 opened 766.25. That 3.35 of empty chart is a gap — overnight, information changed and the first trade of the new day printed lower. No candle covers it, and Stage 2's gap lesson is why stops can't protect you across it.
THE TRAP — THE CANDLE THAT ‘LIES’

A candle records extremes, not residence. One brief print can paint a long wick — a single fast spike to a price where almost nothing traded — and the finished candle then ‘shows’ a dramatic rejection that most of the market never saw. The failure mode compounds on quiet periods: the lighter the trading, the less a candle's shape represents anyone's real conviction. That is why this course reads candles with their volume attached (Lesson 5) and treats every shape-name from the pattern books — hammer, doji, engulfing — as a description of what happened, never as an instruction about what happens next.

GAPS — THE EMPTY SPACE BETWEEN CANDLES

A gap is the distance between one period's close and the next period's open, and it exists because markets close while the world doesn't: earnings, news and world events land overnight, and the first trade of the new day prices them in one jump. Oct 15, 2026 opened 3.35 below Oct 14's close — a real, unremarkable gap on an ordinary day. Two habits follow. First, expect gaps around scheduled news and treat any level drawn from the far side of one as stale until price re-tests it. Second, remember Stage 2: a gap jumps clean over stop prices and limit prices alike — nothing fills inside empty space, because no trading happened there. The gap is the chart's honest admission that continuity is a daytime illusion.

COMMON BEGINNER MISTAKES

  • Reading a candle's colour as the day's verdict versus yesterday. Green means close above this period's open — a gapped-down day can print green and still be down.
  • Treating a long wick as a long visit. The wick records that a price printed, not how long price stayed there or how much traded.
  • Learning shape-names as signals. ‘Hammer’ and ‘engulfing’ describe finished bars; the studies behind the names do not make the next bar obey them.
  • Forgetting the period. A daily candle and a 5-minute candle are the same four prints over different spans — Lesson 2 shows how different the same day looks through each.

DO IT — DECODE THREE CANDLES COLD

Open SPY's daily chart and pick three candles at random — one green, one red, one with a tiny body. For each, write the four prints, the body size, both wicks and the range, in your journal, before reading any commentary anywhere. Then write one sentence per candle: what it records, and one thing it cannot tell you. This decode, done without notes, is the first half of Stage 3's gate.
