TrendGrade Buy Sell Signals
TrendGrade — Buy & Sell Signals (MTF Confirmed)
What it does
TrendGrade is a signal-grading system built on top of a Supertrend trigger. Instead of treating every Supertrend flip as an equal trade opportunity, it classifies each buy signal by quality using trend-strength analysis (XTL), higher-timeframe confirmation, and a transparent rule-based priority score. It is designed primarily for intraday swing timeframes (e.g., 2H) with 4H confirmation and an optional Daily veto.
How it works
1. Base trigger — Supertrend
The entry engine is the classic ATR-based Supertrend (default ATR 14, multiplier 2.0). A buy setup appears when the trend flips from bearish to bullish; a sell setup appears on the opposite flip.
2. Signal grading — XTL (eXpert Trend Locator)
XTL is based on Tom Joseph's statistical concept for separating directional moves from random market noise, implemented here via a Double-CCI-style calculation with a selectable moving-average engine (28 MA types, default VWMA-26 on HLC3) and a fixed threshold (default 37).
XTL above the threshold = BULL environment
XTL below the negative threshold = BEAR environment
Otherwise = NEUTRAL
Optional bar coloring paints candles by XTL state (bull / neutral / bear).
3. Multi-timeframe confirmation (anti-repaint)
4H confirmation: close above the 4H EMA-21, EMA slope flat or rising, plus an optional RSI(14) momentum check (RSI > 50 or rising).
Daily veto (optional): if the Daily close is below its EMA-21 AND the EMA slope is down (strong downtrend), all buy signals are blocked. Blocked signals are still shown on the chart as an orange × for transparency.
By default only closed higher-timeframe bars are used (`lookahead_off` + confirmed-bar indexing), so MTF confirmation does not repaint. This can be disabled for faster (but mutable) live-bar confirmation.
4. Signal classes
STRONG BUY — Supertrend flip + XTL BULL + 4H confirmation (lime label)
BUY — Supertrend flip without full confirmation (green label)
SELL — Supertrend flip down, only fired if a valid buy occurred first (simple position tracking, so sells are not orphaned)
Filtered/blocked raw signals are plotted as gray circles or orange × marks so you can always see what was suppressed and why.
5. Optional EMA-89 filter
Buy signals can additionally be required to close above EMA-89 (with an adjustable % tolerance). Off by default.
6. Priority score (0–100)
Each signal gets a transparent, rule-based score from RSI, MFI, relative volume, EMA ribbon alignment (5/8/13/34/55/89/200), Parabolic SAR position and CMF. This is a simple checklist score — it is NOT a statistical probability.
7. Alerts & webhook automation
Standard `alertcondition()` alerts for Strong Buy / Buy / Sell / trend change.
A structured JSON alert (via `alert()`) designed for webhook automation (e.g., Make.com / n8n): symbol, timeframe, price, ATR-based Target-1/Target-2, Supertrend stop, R:R ratio, priority score, XTL state, 4H/Daily MTF status, RSI/MFI/CMF, relative volume, EMA support/resistance map, and flags such as "volume spike" (relative volume ≥ 3×) and "strong money inflow" (CMF ≥ 0.15).
Optional early intrabar alert: fires before bar close once a configurable percentage of the bar has elapsed (default 60%), clearly tagged `early_mode=1`. Early alerts can be invalidated before the bar closes (repaint risk is explicitly flagged); the confirmed bar-close alert is always sent separately.
Settings overview
Supertrend: ATR period, multiplier, source, ATR method
XTL: length, MA type (28 options), source, threshold, traditional/modern CCI formula
MTF: confirmation timeframe (default 4H), veto timeframe (default 1D), EMA length, slope lookback, momentum check, closed-bar mode
EMA-89 filter, EMA ribbon display, Parabolic SAR display
Targets: ATR multiples for Target-1 / Target-2 (used in alert messages)
Oscillators/volume lengths and attention thresholds (used in alert messages)
Early-signal toggle and minimum bar progress
Repainting notes
Confirmed signals are evaluated on bar close.
MTF data uses `lookahead_off` and, by default, the last closed higher-timeframe bar, so confirmation status does not change retroactively (at the cost of up to one higher-timeframe bar of delay).
The optional early intrabar alert is intentionally repainting by nature and is clearly labeled as a pre-warning; the final confirmation is always sent at bar close.
