SOFT Speed & Linearity Strategy (MTF) LIVE & BACKTEST
SOFT Speed × Linearity Strategy (MTF – LIVE & BACKTEST)
This strategy detects clean impulsive moves by combining real-time price speed with directional quality (linearity).
It is designed for intraday markets such as Gold (XAUUSD), Nasdaq, and Crypto (ETH, BTC), where acceleration quality matters more than raw indicators.
🔹 Core Concepts
1️⃣ Speed ($ per second)
Measures how fast price is moving
Expressed in $/second, not points or ticks
Two execution modes:
LIVE → real-time intra-candle speed using elapsed seconds
BACKTEST → historical approximation using (Close − Open) / candle duration
2️⃣ Linearity Score (1 → 5)
Evaluates movement quality inside the candle:
Net progress vs adverse excursion
Identifies one-way impulses vs noisy back-and-forth moves
Interpretation
1–2 → choppy / rotational
3 → acceptable
4–5 → clean impulse (higher continuation probability)
🔹 Visual Panel
Histogram bars = Speed × Linearity
Color reflects directional quality
Optional info label displays:
Execution mode (LIVE / BACKTEST)
Analysis timeframe
Linearity score
Direction
Speed ($/s)
No drawings are placed on candles.
🔹 Entry Logic
Configurable conditions:
Minimum linearity score
Minimum speed
Direction aligned with candle movement
Long / Short / Both modes
Optional cooldown between signals
⚠️ Speed thresholds are separated for LIVE and BACKTEST to reflect their different nature.
🔹 Exit Modes (Selectable)
A — Symmetric
Exit when entry conditions are no longer valid.
B — Hysteresis (default)
Exit only after controlled degradation:
Linearity falls below a lower threshold
Or speed drops below a lower threshold
C — Momentum
Exit when speed no longer supports the trade direction (speed ≤ 0).
Optional add-ons:
Exit on opposite signal
Exit on speed channel re-entry
🔹 Multi-Timeframe (MTF)
Default analysis timeframe: 15 minutes
Optional lock to chart timeframe
Safety rule for public use:
If chart timeframe < 15m, analysis remains on 15m
Prevents misleading ultra-fast recalculations
🔹 LIVE vs BACKTEST (Important)
LIVE mode uses true intra-candle acceleration
BACKTEST mode uses an approximation to allow reproducible historical testing
Results between LIVE and BACKTEST are not identical by design
This is intentional and clearly separated.
🔹 Alerts
Available alerts:
BUY
SELL
EXIT
Speed channel breakout
ALL events
Compatible with TradingView webhooks.
🔹 Intended Use
This is not a trend indicator.
This is not a prediction tool.
It is a momentum quality detector, useful to:
Validate breakouts
Filter false accelerations
Trade continuation, not anticipation
