DTW Template Tracker [forexobroker]
DTW Template Tracker uses simplified Dynamic Time Warping with a Sakoe-Chiba band (width 2) to align recent z-scored closes against monotone bull (linear rise) and bear (linear fall) templates. DTW allows time stretching that cosine similarity does not. Lower distance = closer match; signal fires when one template's distance is materially lower than the other and below an absolute threshold.
🔶 ALGORITHM
1. Z-score the recent N closes using rolling mean and stdev.
2. Build templates: bull = linspace(-1, +1) over N points; bear = -bull.
3. DTW with Sakoe-Chiba band W = 2: cost matrix D[i,j] is filled only within |i - j| <= W. D[i,j] = |x - t[j]| + min(D[i-1,j-1], D[i-1,j], D[i,j-1]).
4. Bull and bear distances = D[N-1, N-1] under each template.
5. Match when one distance < other AND <= threshold.
🔶 SIGNAL LOGIC
- Buy: bull match edge AND not already long AND cooldown elapsed AND barstate.isconfirmed.
- Sell: bear match edge.
- Position-lock state machine.
🔶 INPUTS
- Template Length (default 15)
- DTW Distance Threshold (default 2.0)
- Cooldown Bars (default 4)
- Visual: dashboard, glow (flag with "match"), template overlay, buy / sell colors
🔶 ALERTS
DTT Buy, DTT Sell, DTT Any Signal, DTT Bull Match, DTT Bear Match, DTT Bull Tight, DTT Bear Tight, DTT Strong, DTT Webhook JSON.
🔶 LIMITATIONS
- DTW cost grows ~ N * W per bar; defaults (N = 15, W = 2) keep compute reasonable. Larger N exceeds Pine compute budget.
- Sakoe-Chiba band W = 2 limits stretch to +/- 2 bars; useful for 1:1 matching with minor jitter.
- Monotone templates only — V-shaped or W-shaped patterns require additional template definitions.
- Z-scoring removes scale; the indicator is invariant to absolute price level.
