NIFTY 500 uses the list on file for the session where there is one. F&O and sectors are today's lists - the run says so.

Average turnover at least (₹ lakh a day)

0 for no liquidity floor. 100 = ₹1 crore a day over 20 sessions.

Conditions

Match of these groups.

Group 1: match of

A name with no value yet for a feature (a new listing without 200 sessions, say) does not pass that condition. Crossings compare this session - or candle - with the one before. Each condition reads daily data unless you pick 5-minute, 15-minute or hourly candles; intraday conditions cover the names whose candles are captured (watched and called names), from the latest candle.

Shows the rules as last loaded or run - edits made in the form since then are not copied here. The same format the form writes. Groups are {"all": [...]} or {"any": [...]} and nest up to four deep; a condition is {"left": "rsi_14", "op": "<", "right": {"value": 35}} or "right": {"feature": "sma_200", "times": 1}.

N consecutive rising candles	pat_rising_run	+1/−1/0	+1 when 'N consecutive rising candles' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: Walk the candles in order. Count a streak: +1 when this close is above the previous close, back to 0 otherwise. The pattern completes on the candle where the streak first reaches N. Report the move from the close before the run to the close that completed it. Progress: how long the current streak is against N, and whether the last close is still rising. Parameters (daily defaults): n=5.
N consecutive falling candles	pat_falling_run	+1/−1/0	+1 when 'N consecutive falling candles' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: Walk the candles in order. Count a streak: +1 when this close is below the previous close, back to 0 otherwise. The pattern completes on the candle where the streak first reaches N. Report the move from the close before the run to the close that completed it. Progress: the current streak against N. Parameters (daily defaults): n=5.
Higher highs and higher lows	pat_higher_highs_lows	+1/−1/0	+1 when 'Higher highs and higher lows' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): swing_pct=3.0, swings=2.
Lower highs and lower lows	pat_lower_highs_lows	+1/−1/0	+1 when 'Lower highs and lower lows' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: Find swing highs and lows with the zigzag (pivot confirmed after a swing_pct move against it). Take every window of 2×swings+1 consecutive confirmed pivots. Require each swing high below the previous swing high, and each swing low below the previous swing low. The pattern completes on the candle where the last pivot was confirmed. The last swing high is reported as the level the structure hangs from. Parameters (daily defaults): swing_pct=3.0, swings=2.
Gap at the open	pat_gap	+1/−1/0	+1 when 'Gap at the open' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): pct=1.0.
Move of X% within M candles	pat_spike	+1/−1/0	+1 when 'Move of X% within M candles' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): candles=3, pct=2.0.
Inside bar, then a breakout	pat_inside_break	+1/−1/0	+1 when 'Inside bar, then a breakout' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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). Parameters (daily defaults): none.
Moving-average cross	pat_ma_cross	+1/−1/0	+1 when 'Moving-average cross' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): fast=9, slow=21.
Volume spike	pat_volume_spike	+1/−1/0	+1 when 'Volume spike' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): candles=20, times=3.0.
RSI into overbought / oversold	pat_rsi_level	+1/−1/0	+1 when 'RSI into overbought / oversold' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): high=70, low=30, n=14.
Bollinger squeeze, then a break	pat_bollinger_break	+1/−1/0	+1 when 'Bollinger squeeze, then a break' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): k=2.0, n=20, squeeze=60.
Trend line: slope, length, strength	pat_trend_run	+1/−1/0	+1 when 'Trend line: slope, length, strength' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): min_r2=0.8, min_slope_pct=0.25, n=20.
Impulse wave (five swings, Elliott-style)	pat_impulse_wave	+1/−1/0	+1 when 'Impulse wave (five swings, Elliott-style)' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: 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. Parameters (daily defaults): swing_pct=4.0.
Bullish engulfing	pat_bullish_engulfing	+1/−1/0	+1 when 'Bullish engulfing' completes on this session going up (or is neutral), −1 going down, 0 otherwise. Rule: Take two consecutive candles. First closes below its open; second closes above its open. Second's open ≤ first's close and second's close ≥ first's open (its body covers the first's body). Context: the net move over the `context` candles before the pair is negative (set 0 to skip). Parameters (daily defaults): context=5.
