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.

What the candles did

Closed at 0.95, below the lower band (0.96) after the bands had narrowed to their tightest in 60 candles.

What this pattern is taken to mean

The bands had narrowed to their tightest in a while, then the close left them. Read as a quiet stretch ending.

What followed on this name's own record

Only 1 earlier hit 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 1 of 1 times, median move -15.00%.

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, k = 2, squeeze = 60

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.

Last seen week of 04 Apr 2022

The most recent hit of Impulse wave (five swings, Elliott-style) on the weekly candles completed at week of 04 Apr 2022, 48 weeks ago, a down reading. It is not in progress now. Since then the close has moved -63.04% to 0.85.

What the candles did

Five swings down: 1 3.45→2.65, 2 back to 3.20 (below where 1 began), 3 to 2.00, 4 back to 2.45 (below the bottom of 1), 5 to 1.85; 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 1.15, 0.95, 1.05, 0.80.

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.

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 1 of 2 times, median move -28.62%.

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

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.
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.

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.

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)

Cross of a level you set · reading up or down · any candleThe close went through a price you chose. Read however you meant the level.

Take the level you entered.
The pattern completes on a candle whose close is at or above the level while the previous close was below it (up), or at or below it while the previous close was above (down).
Nothing is reported until a level is set.

level = 0: Your level, ₹ — Required — leave at 0 and this pattern reports nothing.

Inside bar, then a breakout · reading up or down · any candleA candle whose whole range sat inside the one before it (a pause), then a close outside the mother candle's range. Read as a pause resolving.

Take three consecutive candles: mother, inside, break.
Inside: its high ≤ mother high and its low ≥ mother low.
The pattern completes when the third candle closes above the mother high (up) or below the mother low (down).

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.
