LSMA25 Trend Correction Continuation

## LSMA25 Trend Correction Continuation - Publishing Description

### Overview

This indicator highlights **trend continuation opportunities** using a **25-period LSMA (Least Squares Moving Average)** with a **slope/angle filter** and a simple **correction + re-entry** logic.

It is designed to mark:

* **Continuation entries** after a pullback (correction) and re-cross of LSMA in the direction of a strong trend
* **Strong-trend state** (subtle dots) when price stays on the trend side of LSMA with a steep angle, even without a fresh cross

### Core logic

1. **LSMA (25 by default)**

* Uses `ta.linreg(close, lsmaLen, 0)` as the LSMA line.

2. **Trend strength via angle (tick-normalized)**

* Computes 1-bar LSMA slope in **ticks**:

* `slopeTicks = (lsma - lsma[1]) / syminfo.mintick`
* Converts slope to an angle using `atan()` and a calibration input:

* `ticksPerBarFor45` approximates how many ticks per bar corresponds to ~45°
* Strong trend conditions:

* LONG trend strength when `angleDeg >= minAngleLongDeg`
* SHORT trend strength when `angleDeg <= minAngleShortDeg`

3. **Correction detection**

* LONG side: a correction exists if within the last `corrLookback` bars the close was **below** LSMA:

* `ta.barssince(close < lsma) <= corrLookback`
* SHORT side: correction exists if within the last `corrLookback` bars the close was **above** LSMA:

* `ta.barssince(close > lsma) <= corrLookback`

4. **Continuation signals**

* **Long Continuation (LC)** triggers when:

* Price **crosses above** LSMA (`ta.crossover(close, lsma)`)
* Angle indicates **strong uptrend**
* A recent **pullback below LSMA** occurred
* Optional ATR% filter passes
* **Short Continuation (SC)** triggers symmetrically on cross below.

5. **Strong trend markers**

* When price is on the trend side of LSMA and angle is strong:

* Uptrend: `close > lsma and strongUp`
* Downtrend: `close < lsma and strongDown`
* Drawn as small, semi-transparent circles (not entry signals by themselves).

### Plots and labels

* **LSMA line** plotted in yellow.
* **LC**: green triangle below bar (trend continuation long).
* **SC**: red triangle above bar (trend continuation short).
* **Dots**: tiny circles for strong-trend state when no fresh continuation signal is present.

### Inputs (how to tune)

* **LSMA length**

* Higher = smoother, fewer signals
* Lower = more responsive, more signals/noise
* **Ticks per bar ≈ 45°**

* Calibration control for angle scaling across different instruments/timeframes
* Increase it if angles look too “aggressive”; decrease it if angles look too “flat”
* **Min angle for LONG / Max angle for SHORT**

* Tighten to filter for only steep trends; loosen to allow more setups
* **Max correction bars back**

* Larger values allow older pullbacks to qualify
* Smaller values require a more recent correction

### Optional volatility filter (ATR%)

* When enabled, the script requires:

* `ATR% = (ATR / close) * 100 >= minAtrPct`
* Useful to avoid low-volatility chop (but can filter out valid trends on slow markets).

### How to use (practical)

* Use **LC/SC** as “trend continuation after pullback” markers:

* Prefer trading in the direction of higher timeframe bias (if applicable)
* Consider entries on LC/SC with your own risk rules (stops/targets are not included)
* Use the **strong-trend dots** as a regime filter:

* If dots persist, continuation setups have higher context quality
* If dots disappear frequently, market may be ranging/choppy

### Limitations (important)

* Angle is based on **LSMA 1-bar slope**, so it is sensitive to sudden changes and can vary across markets/timeframes.
* Correction logic is binary: it only checks whether price crossed to the other side of LSMA recently (not depth/structure of pullback).
* Signals depend on **close crossing LSMA**, not intrabar wick behavior.
* Not a full trading system: no position sizing, stops, or take profits.

### Alerts

Alerts fire only on **confirmed bars** (`barstate.isconfirmed`) for:

* “LSMA25 Long continuation”
* “LSMA25 Short continuation”
