Natural Language Rules Engine

You translate the trader's natural language rules into monitoring conditions and check them against the live chart.

Step 1: Define Rules

The trader describes rules in plain English. You translate each into a structured check:

Example rules:

"Alert me when RSI drops below 30 while price is at the VWAP"
→ Check: RSI < 30 AND abs(price - VWAP) < 0.1% of price

"Warn me if I'm about to trade during lunch hours"
→ Check: Current time between 11:30 and 14:00

"Tell me when BankNifty diverges from Nifty by more than 0.5%"
→ Check: abs(BANKNIFTY_change% - NIFTY_change%) > 0.5

"Flag if volume spikes above 3x average"
→ Check: Volume > 3 * Volume_MA

"Alert when price breaks above yesterday's high"
→ Check: Current price > PDH (from yesterday's OHLCV)

Save rules to trading-rules.json:

{
  "rules": [
    {
      "id": 1,
      "name": "RSI Oversold at VWAP",
      "description": "RSI drops below 30 while price is at VWAP",
      "conditions": [
        {"indicator": "RSI", "operator": "<", "value": 30},
        {"indicator": "price_vs_VWAP", "operator": "<", "value": 0.1}
      ],
      "action": "alert",
      "priority": "high",
      "enabled": true
    }
  ]
}

Step 2: Monitor (On-Demand)

When the trader says "check my rules" or you're called during a workflow:

1. data_get_study_values — get all indicator readings
2. quote_get — get current price
3. data_get_pine_tables — VPA signals

For each enabled rule:

• Evaluate all conditions against current data
• If ALL conditions met → TRIGGERED
• If some conditions met → APPROACHING
• If no conditions met → NOT ACTIVE

Step 3: Report

## Rules Monitor — [Time]

### TRIGGERED 🔔
| Rule | Conditions | Action |
|------|-----------|--------|
| RSI Oversold at VWAP | RSI=28 ✓, Price at VWAP ✓ | ALERT: Potential long setup |

### APPROACHING ⚠️
| Rule | Met | Remaining |
|------|-----|-----------|
| Volume Spike | Vol 2.5x avg | Need 3x to trigger |

### NOT ACTIVE
| Rule | Status |
|------|--------|
| BankNifty Divergence | Spread only 0.2% (need 0.5%) |
| Lunch Hour Warning | Not in lunch hours |

Continuous Monitoring

The trader can set up periodic monitoring using Claude Code's /loop or cron:

• "Check my rules every 5 minutes" → /loop 5m /tv-rules-check
• Rules are checked, alerts shown only when state changes (new trigger or cleared)

Rules

• Keep rules simple — each rule should have 2-3 conditions max
• Rules don't execute trades — they ALERT the trader to look at the chart
• When a rule triggers, suggest running /tv-validate-trade for a full setup check
• Store rules persistently — they should survive across sessions
