Patterns

Every pattern here is a rule over stored candles, written out step by step below. Pick a name and a candle size, then one pattern to test — or let the library look for anything in progress. A hit is an observation of what the candles just did; what followed the earlier hits on the same name is counted and shown beside it, every hit included.

Hit on the latest weekly candle — week of 05 Oct 2026

Trend line: slope, length, strength has held from the candle of week of 28 Sep 2026 through the newest one on file (2 weeks), a down reading. It is in progress now.

What the candles did

Over the last 20 candles the fitted line falls 0.95% per candle with R² 0.90; 18 candles since the high of the window, -21.37% from it, and the last close is still with the line.

Where it stands on the latest candle

Slope -1.02% per candle (down), R² 0.90 (straight), 19 candles from the window's high, -21.05% from it; the last close is with the line.

What this pattern is taken to mean

The straight-line fit through the last N closes: how steep, how long, how clean. This is the slope/length/strength reading (R6) and a version of the 20-candle rule that fires on a clean run even when one close in the middle dipped.

What followed on this name's own record

Only 2 earlier hits on this name's weekly candles with 4 weeks after them — too few to say what usually follows. For what it is worth: the close 4 weeks later went the hit's way 0 of 2 times, median move -10.25%.

An observation from stored candles, not advice. Nothing here is a forecast; the decision, and the risk, are yours.

The rule, exactly as checked · n = 20, min_slope_pct = 0.25, min_r2 = 0.8

Fit a least-squares line through the last N closes (x = candle index).
Slope % = slope / mean close × 100, per candle. R² = share of the variance the line explains (1 = a ruler, 0 = chop).
Length = candles since the window's low (for a rising line) or high (falling). Magnitude = % from that extreme to the last close.
Continuing = the last close is on the slope's side of the fitted line, or the last three closes all moved with the slope.
The pattern completes when |slope %| ≥ min_slope_pct and R² ≥ min_r2; consecutive qualifying candles count once, at the first.
Progress always reports the current slope, R², length, magnitude and whether it is continuing.

What the candles did

Five swings down: 1 157.89→145.26, 2 back to 152.57 (below where 1 began), 3 to 138.00, 4 back to 145.01 (below the bottom of 1), 5 to 126.15; wave 3 is not the shortest.

Where it stands on the latest candle

Counting down: waves 1–2 confirmed, wave 3 under way (the current swing has not yet reversed by 4%). Pivots so far 160.39, 141.30, 154.90, 133.00.

What this pattern is taken to mean

Five alternating swings that obey the three classical impulse rules. A count, not a prophecy: the same swings can be counted more than one way, and this is the plain mechanical reading.

The rule, exactly as checked · swing_pct = 4

Find swings with the zigzag at swing_pct.
Take six consecutive confirmed pivots L-H-L-H-L-H (up) or H-L-H-L-H-L (down).
Rule 1: wave 2 does not retrace past the start of wave 1.
Rule 2: wave 3 is not the shortest of waves 1, 3 and 5.
Rule 3: wave 4 does not enter the price territory of wave 1.
Each wave must make progress: 3 beyond 1, 5 beyond 3.

Higher highs and higher lows · reading up · any candleUptrend structure: each swing high above the last and each swing low above the last. Read as a trend that is still being confirmed by its pullbacks.

Find swing highs and lows with the zigzag: a pivot is confirmed once price has moved swing_pct against it.
Take every window of 2×swings+1 consecutive confirmed pivots.
Require each swing high in the window above the previous swing high, and each swing low above the previous swing low.
The pattern completes on the candle where the last pivot in the window was confirmed.
The last swing low is reported as the level the structure stands on.

swings = 2: Higher highs / higher lows required
swing_pct = 3: Minimum swing size, % — Smaller on intraday candles.

Gap at the open · reading up or down · any candleThe session opened at least X% away from the previous close. Read as news or flow arriving overnight.

At the first candle of each session, compare its open with the last close of the previous session.
Gap % = open / previous close − 1.
The pattern completes when |gap %| ≥ pct; direction is the gap's sign.
On daily candles this is simply open vs the previous day's close.

pct = 1: Minimum gap, %

Move of X% within M candles · reading up or down · any candleA fast move: the close is at least X% away from where it was M candles ago. Read as a burst of one-sided flow.

For each candle, take the close M candles earlier.
Move % = close now / close then − 1.
The pattern completes when |move %| ≥ pct; direction is the sign.
Consecutive candles that all qualify in the same direction count once, at the first of them.

pct = 2: Minimum move, %
candles = 3: Within this many candles (M)

Indicator-based

Rules on a derived line: moving averages, VWAP, volume, RSI, Bollinger bands.

Moving-average cross · reading up or down · any candleThe faster simple average crossed the slower one. Read as the near-term average price overtaking (or falling behind) the longer one.

Compute SMA(fast) and SMA(slow) of the closes.
The pattern completes on a candle where fast was ≤ slow on the previous candle and is > slow now (up), or ≥ before and < now (down).
fast must be smaller than slow, else nothing is reported.

fast = 9: Fast average, candles
slow = 21: Slow average, candles

Volume spike · reading up or down · any candleOne candle traded many times the recent average volume. Read as attention arriving; the candle's colour says which way it leaned.

Average the volume of the previous M candles (those that reported one).
The pattern completes when this candle's volume ≥ times × that average.
Direction is the candle's own: up if it closed above its open, down if below, neutral if flat.

times = 3: Multiple of the average
candles = 20: Average over this many candles (M)

RSI into overbought / oversold · reading up or down · any candleWilder's RSI crossed into the overbought zone (reported as a 'down' observation: stretched) or the oversold zone ('up': washed out).

Compute RSI(n) from the closes (Wilder smoothing).
The pattern completes when RSI moves from below `high` to at or above it (overbought → down), or from above `low` to at or below it (oversold → up).
Only the crossing candle is a hit, not every candle spent inside the zone.

n = 14: RSI length
high = 70: Overbought above
low = 30: Oversold below

Bollinger squeeze, then a break · reading up or down · any candleThe bands had narrowed to their tightest in a while, then the close left them. Read as a quiet stretch ending.

Compute Bollinger bands: SMA(n) ± k × standard deviation of the last n closes; bandwidth = (upper − lower) / middle.
Squeeze: the smallest bandwidth in the last 6 candles is within 5% of the smallest over the last `squeeze` candles.
The pattern completes on a candle that closes above the upper band having been at or below it the candle before (up), or the mirror below the lower band (down), while squeezed.

n = 20: Band length
k = 2: Standard deviations
squeeze = 60: Tightest in this many candles

Trend and waves

The fitted trend line and the swing count. A wave count is a reading of the swings, not a prophecy.

Trend line: slope, length, strength · reading up or down · any candleThe straight-line fit through the last N closes: how steep, how long, how clean. This is the slope/length/strength reading (R6) and a version of the 20-candle rule that fires on a clean run even when one close in the middle dipped.

Fit a least-squares line through the last N closes (x = candle index).
Slope % = slope / mean close × 100, per candle. R² = share of the variance the line explains (1 = a ruler, 0 = chop).
Length = candles since the window's low (for a rising line) or high (falling). Magnitude = % from that extreme to the last close.
Continuing = the last close is on the slope's side of the fitted line, or the last three closes all moved with the slope.
The pattern completes when |slope %| ≥ min_slope_pct and R² ≥ min_r2; consecutive qualifying candles count once, at the first.
Progress always reports the current slope, R², length, magnitude and whether it is continuing.

n = 20: Candles in the fit (N)
min_slope_pct = 0.25: Minimum slope, % per candle
min_r2 = 0.8: Minimum R²

Impulse wave (five swings, Elliott-style) · reading up or down · any candleFive alternating swings that obey the three classical impulse rules. A count, not a prophecy: the same swings can be counted more than one way, and this is the plain mechanical reading.

Find swings with the zigzag at swing_pct.
Take six consecutive confirmed pivots L-H-L-H-L-H (up) or H-L-H-L-H-L (down).
Rule 1: wave 2 does not retrace past the start of wave 1.
Rule 2: wave 3 is not the shortest of waves 1, 3 and 5.
Rule 3: wave 4 does not enter the price territory of wave 1.
Each wave must make progress: 3 beyond 1, 5 beyond 3.
The pattern completes when the sixth pivot is confirmed. Progress reports 'wave 5 under way' when the first five pivots hold and the live swing is the fifth wave.

swing_pct = 4: Minimum swing size, %

Indicator definitions: SMA(n) is the mean of the last n closes. RSI(n) is Wilder's — average gain over average loss, smoothed by (previous × (n−1) + now) / n. ATR(n) is the Wilder-smoothed mean of the true range. Bollinger bands are SMA(n) ± k standard deviations of the same n closes. VWAP is Σ(typical price × volume) / Σ volume within the session, typical price = (high + low + close) / 3. The trend line is ordinary least squares on close against candle index. Swings come from a zigzag that confirms a pivot once price has moved the swing size against it.
