Wyckoff Distribution Phase Map [AGPro Series]Wyckoff Distribution Phase Map 🔹 OVERVIEW Wyckoff Distribution Phase Map is a retrospective structural mapping tool built on the classic Wyckoff distribution schematic. It locates and labels the six core distribution events — Preliminary Supply (PSY), Buying Climax (BC), Automatic Reaction (AR), Upthrust (UT), Sign of Weakness (SOW) and Last Point of Supply (LPSY) — only after a bearish Change of Character (CHoCH) confirms that the prior uptrend has structurally broken. The indicator frames the active trading range as a shaded zone, plots BC and AR horizontal references, and tracks the phase state (A, B, C, D, E) in a dedicated info panel with a forming-candidate watchlist before confirmation. 🔹 WHAT MAKES IT DIFFERENT Most Wyckoff scripts on TradingView label events reactively on every elevated swing, producing dense, often contradictory signals during ranging or trending markets. This indicator takes the opposite approach. During an uptrend, the chart remains completely clean. Rolling trackers silently maintain candidate values for BC, PSY and AR in memory, while a live watchlist row in the panel shows the forming distribution candidate in real time. Events are only drawn on the chart after CHoCH locks the schematic, at which point PSY, BC and AR appear together as a confirmed retrospective bundle. UT, SOW and LPSY then populate as the post-CHoCH structure unfolds. A two-tier expiry system closes both incomplete and fully-played-out distributions, ensuring the active schematic on screen always reflects current market structure — not stale history. 🔹 METHODOLOGY The engine runs in two coordinated layers. The first layer tracks higher-high and higher-low sequences to qualify an uptrend and rolls candidate values for the Buying Climax (running maximum swing high), Preliminary Supply (last pre-BC elevated swing high) and Automatic Reaction (running minimum after BC). The second layer watches for a structural break below the last confirmed higher-low, which defines the CHoCH. On CHoCH confirmation, the candidate values are snapshotted as BC, PSY and AR labels, the trading range zone is drawn, and the state machine advances to the forward-detection phase. Upthrust, Sign of Weakness and Last Point of Supply are then detected in strict sequence using a combination of price-to-BC, price-to-AR and volume-to-average filters. Volume context is computed against a 20-period moving average baseline with separate climactic, elevated and weak thresholds tuned for crypto and equities alike. 🔹 SIGNALS AND ALERTS The indicator fires two categories of alerts. The CHoCH Confirmation alert triggers the moment the structural break locks in, including the resolved BC and AR levels. Event alerts fire for each subsequent UT, SOW and LPSY detection. No alert is fired during the forming phase — alerts are reserved for confirmed structural events, keeping notification noise low. A projected markdown line is drawn forward from LPSY using the trading range height as a symmetrical target, purely as a visual reference point rather than a trade signal. 🔹 KEY INPUTS Core Engine inputs control swing lookback sensitivity, candidate maximum age and the post-CHoCH timeout window. Volume Analysis exposes the moving average length and three multipliers for climactic, elevated and weak volume classification. Visual inputs toggle the trading range zone, BC and AR horizontal levels, the CHoCH dashed break line, the markdown projection, the confidence halo and the floating distribution summary label, with full control over font size, line widths and zone transparency. The info panel can be repositioned to six anchor points and switched between dark and light themes. A Keep Historical Events toggle allows old schematics to remain on the chart after reset, off by default for a clean view. 🔹 HOW TO USE Apply the indicator to any liquid instrument and any timeframe. During uptrends, observe the Watching row in the panel to monitor the forming BC candidate. When CHoCH prints, the full PSY, BC, AR bundle appears with the trading range shaded. From that point, use the Next Expected row to track what the engine is waiting for. The confidence score progresses from 70 at CHoCH to 97 at LPSY. The floating summary label on the right edge of the chart provides an at-a-glance status even when the primary event labels are scrolled off to the left. The indicator works standalone but is designed to complement any market structure, order flow or supply-and-demand workflow. 🔹 LIMITATIONS AND TRANSPARENCY This tool is a pattern-recognition and labeling engine, not a strategy or trading signal generator. All events are detected retrospectively after their confirming bar has closed plus the swing lookback period — this is by design to eliminate redrawing. The Wyckoff schematic is a framework, not a deterministic forecast; not every distribution completes the full six-event sequence, and markets frequently fail schematics entirely and resume the prior trend. The volume analysis assumes reliable reported volume, so thin or fragmented markets may produce weaker classification. Confidence scores are internal heuristics tied to event progression, not statistical probabilities. Past schematic completions do not predict future market behavior. 🔹 RISK DISCLOSURE This indicator is published for educational and analytical purposes only. It does not constitute financial advice, a trading recommendation or an investment solicitation. Trading any financial instrument involves substantial risk, including the potential loss of principal. Past performance does not guarantee future results. Users are solely responsible for their own trading decisions, risk management and independent research. Always backtest thoroughly and trade within a risk framework you understand.

Zigzag Array ExperimentalThis is experimental script for zigzag which uses type, method and array. Not recommend for actual usage, for pine script study maybe useful. In this experiment, I use type as coded below. It seems have limitation as specially when push as array. As Trading View recommendation, pushing float and int into array especially for type not guarantee to work. I agree with that. Preferred to push array as line or label especially for types. // @type Used for point especially for array // @field x int value for bar_index // @field y float value for price // @field sty label style // @field col color for text label // @field str high or low string type point int x = na float y = na string sty = na color col = na string str = na I simulate the arrays as below. var dirLine = array.new() var dirLabel = array.new() var dirPoint = array.new() .... dirPoint.unshift(zigzag.createPoint(0)) dirLabel.unshift(zigzag.createLabel(fontSize, 0, true)) dirLine.unshift(zigzag.createLine(width, switchLine, 0, true)) Here are some results.

Forecasting - Holt’s Linear Trend ForecastingHolt's Forecasting method Holt (1957) extended simple exponential smoothing to allow the forecasting of data with a trend. This method involves a forecast equation and two smoothing equations (one for the level and one for the trend): Forecast equation: ŷ = l + h * b Level equation: l = alpha * y + (1 - alpha) * (l + b) Trend equation: b = beta * (l - l) + (1 - beta) * b where: l (or l) denotes an estimate of the level of the series at time t, b (or b) denotes an estimate of the trend (slope) of the series at time t, alpha is the smoothing parameter for the level, 0 ≤ alpha ≤ 1, and beta is the smoothing parameter for the trend, 0 ≤ beta ≤ 1. As with simple exponential smoothing, the level equation here shows that l is a weighted average of observation y and the one-step-ahead training forecast for time t, here given by l+b. The trend equation shows that b is a weighted average of the estimated trend at time t based on l-l and b, the previous estimate of the trend. The forecast function is not flat but trending. The h-step-ahead forecast is equal to the last estimated level plus h times the last estimated trend value. Hence the forecasts are a linear function of h.
