Altan TV Bot V1 - EMA Signal Indicator
📊 ALTAN TV BOT V1 — Multi-Layer EMA Crossover with RSI & Trend Filter
A professional-grade signal indicator that combines classic EMA crossover
logic with RSI momentum confirmation and long-term trend filtering. Designed
to reduce false signals through a three-stage confirmation mechanism, making
it especially suitable for trending markets and crypto pairs.
This indicator is webhook-ready and integrates directly with automated
trading bots via JSON-formatted alert messages.
═══════════════════════════════════════════════════════════
🎯 CORE CONCEPT
Most EMA crossover strategies suffer from whipsaws in ranging markets.
This indicator addresses that weakness by requiring THREE independent
confirmations before generating a signal:
1. Momentum Shift — Fast EMA crosses Slow EMA
2. Momentum Strength — RSI confirms the directional bias
3. Trend Alignment — Price is on the correct side of the 200 EMA
Only when all three align does the indicator emit a signal. This
significantly reduces noise while preserving the core benefit of EMA
crossovers: early trend entry.
═══════════════════════════════════════════════════════════
⚙️ INDICATOR COMPONENTS
- Fast EMA (20) — Short-term price momentum
Tracks immediate directional bias and reacts quickly to price action.
- Slow EMA (50) — Medium-term trend direction
Smooths short-term noise and defines the dominant swing direction.
- Trend EMA (200) — Long-term trend filter
Acts as the structural trend anchor. Signals only fire in the
direction of this long-term trend.
- RSI (14) — Momentum strength confirmation
Filters out weak crossovers by requiring meaningful momentum
(>55 for longs, <45 for shorts).
═══════════════════════════════════════════════════════════
📈 SIGNAL LOGIC
LONG ENTRY — All three conditions must be true simultaneously:
✓ Fast EMA (20) crosses ABOVE Slow EMA (50)
✓ RSI (14) is ABOVE 55
✓ Close price is ABOVE Trend EMA (200)
SHORT ENTRY — All three conditions must be true simultaneously:
✓ Fast EMA (20) crosses BELOW Slow EMA (50)
✓ RSI (14) is BELOW 45
✓ Close price is BELOW Trend EMA (200)
Why these specific thresholds?
— RSI 55/45 (instead of classic 70/30) catches momentum EARLIER,
before the move becomes overextended.
— EMA 200 filter ensures alignment with structural trend, preventing
counter-trend entries that often fail.
— Crossover requirement (not just "above/below") ensures the signal
is a FRESH momentum shift, not a late entry.
═══════════════════════════════════════════════════════════
🔔 WEBHOOK-READY ALERT SYSTEM
The indicator includes two pre-configured alert conditions that emit
JSON payloads compatible with automated trading systems:
{
"bot_id": "tv_ema_breakout_v1",
"symbol": "{{ticker}}",
"timeframe": "{{interval}}",
"action": "long_entry" | "short_entry",
"price": "{{close}}",
"timestamp": "{{timenow}}"
}
This payload is production-tested and works with:
• Alpaca (paper and live trading APIs)
• Hyperliquid (DEX spot/perp execution)
• Binance (spot trading via webhook)
• Custom Python/Node.js webhook receivers
• Any system that parses JSON webhook payloads
The payload structure keeps integration minimal — your backend only
needs to parse 5 fields to execute a trade.

📋 USER-ADJUSTABLE PARAMETERS
┌─────────────────────┬─────────┬──────────────────────────┐
│ Parameter │ Default │ Recommended Range │
├─────────────────────┼─────────┼──────────────────────────┤
│ Fast EMA │ 20 │ 10-30 │
│ Slow EMA │ 50 │ 30-100 │
│ Trend EMA │ 200 │ 100-300 │
│ RSI Length │ 14 │ 10-21 (standard) │
│ RSI Bull Threshold │ 55 │ 50-65 │
│ RSI Bear Threshold │ 45 │ 35-50 │
└─────────────────────┴─────────┴──────────────────────────┘
Suggested parameter sets:
🐢 CONSERVATIVE (fewer signals, higher quality)
Fast 20 / Slow 50 / Trend 200 / RSI 60/40
⚖️ BALANCED (default)
Fast 20 / Slow 50 / Trend 200 / RSI 55/45
🐆 AGGRESSIVE (more signals, more noise)
Fast 12 / Slow 26 / Trend 100 / RSI 52/48
═══════════════════════════════════════════════════════════
💡 BEST PRACTICES
Recommended Timeframes:
• 4H — Best balance between signal frequency and quality
• 1D — Highest quality signals for position trading
• 1H — Acceptable for active swing traders
• 15m — Use with caution; significant noise in crypto markets
• <15m — NOT recommended; false signal rate too high
Recommended Markets:
✓ Trending crypto pairs (BTC, ETH, SOL) on major exchanges
✓ Large-cap stocks with clear trends
✓ Forex majors during trending sessions
✗ Ranging/choppy markets — expect whipsaws
✗ Low-liquidity altcoins — noise dominates signal
Risk Management:
This indicator is a SIGNAL generator, not a complete trading system.
Always combine with:
• Position sizing rules (1-2% risk per trade)
• Stop-loss placement (below recent swing low for longs)
• Take-profit targets (ATR-based or resistance levels)
• Market regime awareness (don't short during strong bull trends)
═══════════════════════════════════════════════════════════
🎨 VISUAL OUTPUT
The indicator plots three EMAs directly on the chart:
• Fast EMA (20) — Orange line (2px)
• Slow EMA (50) — Blue line (2px)
• Trend EMA (200) — Green line (2px)
Signal labels appear at bar close:
🟢 BUY label below the bar (on long entry)
🔴 SELL label above the bar (on short entry)
The EMA arrangement alone provides visual context:
• Bullish alignment: Orange > Blue > Green (price above all)
• Bearish alignment: Green > Blue > Orange (price below all)
• Transition zones: EMAs converging/crossing signal regime change
═══════════════════════════════════════════════════════════
🔬 BACKTESTING NOTES
This indicator does NOT include a built-in strategy tester to remain
lightweight and performant. For backtesting:
1. Copy the signal conditions into a Pine Script strategy template
2. Add entry/exit logic with your preferred risk rules
3. Use TradingView's Strategy Tester with realistic commission/slippage
Observed historical performance (anecdotal, not guaranteed):
• Crypto 4H trending periods: ~55-65% signal accuracy
• Ranging periods: ~30-40% (as expected — avoid these)
• Stock market daily: ~50-58% with longer holding periods
═══════════════════════════════════════════════════════════
