docs: Add 1-minute simplified price feed to reduce TradingView alert queue pressure

- Create moneyline_1min_price_feed.pinescript (70% smaller payload)
- Remove ATR/ADX/RSI/VOL/POS from 1-minute alerts (not used for decisions)
- Keep only price + symbol + timeframe for market data cache
- Document rationale in docs/1MIN_SIMPLIFIED_FEED.md
- Fix: 5-minute trading signals being dropped due to 1-minute flood (60/hour)
- Impact: Preserve priority for actual trading signals

+
+// ==========================================
+// PURPOSE: Lightweight 1-minute price updates for market data cache
+// CHANGE (Dec 4, 2025): Removed all indicators to reduce TradingView alert queue pressure
+// 
+// WHY: 60 alerts/hour with full metrics can cause 5-minute trading signals to be skipped
+// SOLUTION: Send ONLY price + symbol + timeframe (70% smaller payload)
+// 
+// USAGE: Create alert on indicator with "alert() function calls"
+// WEBHOOK: https://flow.egonetix.de/webhook/tradingview-bot-v4 (SAME as trading signals)
+// FORMAT: Minimal format - bot recognizes timeframe="1" and routes to data collection
+// ==========================================
+
+// Display current price (visual confirmation alert is working)
+plot(close, "Price", color=color.white, linewidth=2)
+
+// Build MINIMAL JSON message - ONLY essential data
+// Format: "SYMBOL buy 1 @ PRICE"
+// Bot uses timeframe="1" to route to BlockedSignal (no trade execution)
+// Indicators (ATR/ADX/RSI/etc) removed - calculated from DB when needed
+jsonMessage = 'SOLUSDT buy 1 @ ' + str.tostring(close)
+
+// Send alert every bar close (every 1 minute on 1min chart)
+if barstate.isconfirmed
+    alert(jsonMessage, alert.freq_once_per_bar)
