MACD 背离 · 快速实时 / 不重绘 · 基于直方图（CN）

多数“MACD 背离”指标要么重绘严重（回测很漂亮、实盘不靠谱），要么触发很滞后（等几根 K 线后才给线/给提醒）。
这个脚本是我在十几版迭代中打磨出的方案(还是跟我的印度导师)：在保持收盘级别不重绘的同时，尽可能把信号“提前到条内”，并且把“提前”和“稳健”两种需求拆开、让你按场景选择。

这款脚本为什么更好？

双模式，实盘&回测都可靠

确认模式（不重绘）：只在枢轴成立时（上一根确认为顶/底）画线并提醒，收盘后不会改变，适合回测与稳健交易。

预判预览（零延迟，可选）：条内一旦出现“价格创更高/更低而柱值更低/更高”的背离形态，就即时画“临时预判线”并提醒；如果形态被否定，会在本根内自动撤回。该模式给你“更早的入场观察”，但可能被取消。

基于 MACD 直方图：直接比较“柱值高/低”和“价格高/低”，不靠模糊的平滑线，背离定义清晰、可见性强。

多重背离/三背离：支持向前连接多段峰/谷，不是只找最近一段，把分层背离也抓出来。

分段规则可控

同侧最小间隔（柱）：避免“同一段内频繁连线”。

可选“跨色分段（红→绿→红 / 绿→红→绿）”：只在真正换势后才允许下一段，显著减少“同色内伪背离”。

即时提醒，严格对齐

预判提醒：只有当图表上真的画出了“临时预判线”时才触发，不会“响了但没线”。

确认提醒：当正式背离线落地的那一刻触发，用于“信号确认”。

视觉简洁：顶背离线=红色，底背离线=绿色；标签可开关，不挡柱不抢视线。

通用：适配任意周期、任意交易品种；参数默认即可用，也可按策略微调。

如何使用（建议）

做回测/稳健交易：仅开“确认提醒”，并把“即时模式（条内）”关闭，得到严格不重绘的标注与提醒。

做超短线/埋伏：打开即时模式 + 零延迟预览，启用预判提醒；当预判线出现就会立马提醒（未确认时可能被撤回）。

如想减少“跨段过远”的连线，可调大同侧最小间隔或打开跨色分段。

需要三背离/多背离，可把“最多向前连接几段”设为 3 或更高。

提示：预判是“更早但可能被否定”，确认是“稳健且不重绘”。两者结合，既看得早，也落得稳。

English Description

MACD Divergence • Fast Live / No-Repaint • On Histogram

Most “MACD divergence” indicators either repaint heavily (great in hindsight, unreliable in live trading) or lag badly (you get lines/alerts several bars late).
This script has gone through 10+ iterations to strike the right balance: deliver earlier signals in real-time while keeping a truly no-repaint confirmation path. You decide when you need early preview or strict confirmation.

What makes it different?

Two operating modes—choose per scenario

Confirmation mode (No-Repaint): Lines/alerts are printed only when the pivot is confirmed (previous bar), and they never change after close. Perfect for backtesting and conservative trading.

Zero-Lag Preview (optional): As soon as an in-bar divergence forms on the histogram (price makes a higher high/lower low while the bar value fails), a temporary preview line is drawn immediately and an alert is fired; if invalidated before the bar closes, it’s removed. Earlier visibility with the right caveat.

Histogram-based logic: We compare bar heights against price highs/lows—clear definition and strong visual readability.

Multi-link divergences (incl. triple): Not limited to the nearest swing—you can extend lines across multiple prior pivots to capture stacked divergences.

Controllable segmentation

Minimum bars between same-side pivots to avoid noisy over-linking.

Optional cross-color segmentation (red→green→red / green→red→green) to reduce false divergences within a same-color run.

Alerts that match what you see

Preview alert fires only when a preview line is actually drawn—no more alerts without lines.

Confirmation alert fires when the final line is committed.

Clean visuals: Bearish lines = red, Bullish lines = green; labels are optional to keep the histogram unobstructed.

Works everywhere: Any symbol, any timeframe. Defaults are sensible; parameters can be tuned to your workflow.

Suggested workflow

Backtest / conservative execution: Use Confirmation alerts only, turn Live (in-bar) evaluation off to ensure strict no-repaint behavior.

Scalping / early entries: Turn Live mode + Zero-Lag Preview on and enable Preview alerts—you’ll be notified the moment a preview line appears (it may retract before close).

Increase Min same-side spacing or enable Cross-color segmentation to limit stretched links.

Raise Max links to capture double/triple divergences.

TL;DR: Preview = earlier but retractable. Confirmation = slower but rock-solid. Combine both to see early and act with confidence.
