Uptrick: Band Flow

• WMA baseline: weights recent closes more heavily than a simple average, so the center line reacts sooner at the same length.
• EMA smoothing pass: reduces bar-to-bar noise in the baseline so the band center does not jitter.
• ATR band width: scales the envelope to current volatility instead of a fixed price distance. Separate upper and lower multipliers allow an asymmetric envelope.
• Trend state with memory: price inside the bands keeps the previous trend, and only a close beyond the opposite band flips it. This replaces a plain baseline cross, so touching the center line alone does not change the trend.
• Single-position signal engine: a new label is only issued when direction changes, so repeated breakouts in the same direction do not stack signals.
• Entry-frozen ATR ladder: ATR is captured on the signal bar, so the five target levels stay fixed instead of moving with volatility after entry.
• Selectable signal anchor: label placement is separated from signal logic, so labels can sit on the trail edge or beyond the candle without changing when signals occur.

• Smoothed baseline: weighted moving average of close with an optional EMA smoothing pass
• ATR is floored at the symbol's minimum tick so band width never collapses to zero
• Upper and lower ATR bands with independent multipliers
• Trend state with memory: a close that crosses above the upper band turns the trend bullish, a close that crosses below the lower band turns it bearish, and price inside the bands keeps the previous state
• Trend changes are evaluated on confirmed bar closes only
• Three overlay modes: Center, Trail and Bands
• Center mode: baseline line in the trend color with a gradient fill between the baseline and price
• Trail mode: one-sided trail, lower trail in an uptrend and upper trail in a downtrend, with a gradient between the inner edge and an outer edge expanded by extra ATR
• Bands mode: full upper and lower envelope with a gradient that is strongest near the baseline
• Trend candles: candle body, border and wick colored by trend state (cyan for bullish, magenta for bearish)
• Up and Down labels, one per direction change, no pyramiding
• Two signal anchor modes: Bands and ATR
• Five ATR take-profit levels measured from the entry close, each marked with a small cross when reached
• Each take-profit level marks once per signal, and all levels reset on the next signal
• Dashboard in the top right corner, two columns by six rows: script name and trend state, trend direction, overlay mode, signal anchor mode, entry price, take-profit progress shown as five dots
• Seven alert conditions: Up, Down, TP1, TP2, TP3, TP4 and TP5
• Display toggles for signals, trend candles, dashboard and take-profit markers
• Written in Pine Script v6 using only the chart's own data, with no request.security calls

• Trend Length (default 30): length of the weighted moving average baseline
• Trend Smoothing (default 4): EMA length applied to the baseline, set to 1 to switch the smoothing off
• Band ATR Length (default 14): ATR period used for band width and for the take-profit distances
• Upper Band Multiplier (default 1.50): ATR multiple added above the baseline
• Lower Band Multiplier (default 1.50): ATR multiple subtracted below the baseline

• Overlay Mode (default Bands): Center, Trail or Bands
• Trail Outer Expansion (default 0.85): extra ATR added to the outer trail edge. Also moves the labels when Signal Anchor is set to Bands
• Trail Smoothing (default 5): EMA length applied to the baseline and ATR used for the outer trail edge, set to 1 to switch off. Also moves the labels when Signal Anchor is set to Bands

• Signal Anchor (default Bands): Bands places labels on the outer trail edge (below price for Up, above price for Down). ATR places them beyond the candle low or high. This changes label position only, not when signals occur
• Signal ATR Length (default 14): ATR period used for ATR-anchored labels
• Signal ATR Distance (default 0.80): ATR multiple between the candle low or high and the label

• Show ATR Take Profits (default on): switches take-profit markers and take-profit alerts on or off
• TP1 ATR, TP2 ATR, TP3 ATR, TP4 ATR, TP5 ATR (defaults 1.0, 2.0, 3.0, 4.0, 5.0): ATR multiple for each target level, measured from the entry close

• Show Signals (default on): Up and Down labels
• Trend Candles (default on): trend-colored candles
• Dashboard (default on): dashboard table

• Use standard candlestick or bar charts. Heikin Ashi, Renko, Kagi, Point and Figure and Range charts do not show real traded prices, so signals and targets on them would not be realistic
• Read the trend from the color: cyan is bullish, magenta is bearish. The color only changes when a close breaks the opposite band
• Treat an Up or Down label as confirmation that a close has left the envelope, not as an early warning
• Tune the band multipliers to set how far price must travel from the baseline before the trend flips: smaller multipliers generally flip sooner and more often, larger multipliers generally flip later and less often. Trend Length changes how closely the baseline follows price, which moves where the bands sit, so test length changes on your own markets rather than assuming a direction
• Pick the overlay mode you prefer: Center for a minimal view, Trail for a one-sided trail, Bands for the full envelope
• Use the ATR targets as reference distances from entry. They are not orders or predictions
• For alerts, open the alert dialog, select Band Flow and choose a condition. Up and Down conditions are only true on a bar close. Take-profit conditions can become true while a bar is still forming, so choose the alert frequency accordingly
