π¨ QA Action Checklist - Critical Fixes Required
Date: 2025-12-03
Priority: HIGH - Must fix before production
β CRITICAL FIXES (Do First)
1. Remove Demo OHLCV Data Generation
File: static/pages/trading-assistant/trading-assistant-professional.js
Current Code (Lines 485-520):
// Last resort: Generate demo OHLCV data
console.warn(`[API] All sources failed for ${symbol} OHLCV, generating demo data`);
return this.generateDemoOHLCV(crypto.demoPrice || 1000, limit);
// ... generateDemoOHLCV function exists ...
Fix Required:
- β Remove
generateDemoOHLCV()function call - β Remove
generateDemoOHLCV()function definition - β Replace with error state:
// All sources failed - show error
throw new Error(`Unable to fetch real OHLCV data for ${symbol} from all sources`);
Status: β NOT FIXED
2. Increase Aggressive Polling Intervals
2.1 Trading Assistant Ultimate
File: static/pages/trading-assistant/trading-assistant-ultimate.js
- Current:
updateInterval: 3000(3 seconds) - Fix: Change to
updateInterval: 30000(30 seconds) or60000(60 seconds) - Status: β NOT FIXED
2.2 Trading Assistant Real
File: static/pages/trading-assistant/trading-assistant-real.js
- Current:
updateInterval: 5000(5 seconds) - Fix: Change to
updateInterval: 20000(20 seconds) or30000(30 seconds) - Status: β NOT FIXED
2.3 Trading Assistant Enhanced
File: static/pages/trading-assistant/trading-assistant-enhanced.js
- Current:
updateInterval: 5000(5 seconds) - Fix: Change to
updateInterval: 20000(20 seconds) or30000(30 seconds) - Status: β NOT FIXED
3. Remove Direct External API Calls
File: static/pages/trading-assistant/trading-assistant-professional.js
Current Code (Lines 334-362):
// Priority 2: Try CoinGecko directly (as fallback)
try {
const url = `${API_CONFIG.coingecko}/simple/price?ids=${coinId}&vs_currencies=usd`;
// ... direct call ...
}
// Priority 3: Try Binance directly (last resort, may timeout - but skip if likely to fail)
// Skip direct Binance calls to avoid CORS/timeout issues - rely on server's unified API
Fix Required:
- β Remove direct CoinGecko call (lines 334-362)
- β Keep only server unified API call
- β Throw error if server API fails (no fallback to external)
Status: β οΈ PARTIALLY FIXED (Binance removed, CoinGecko still present)
β οΈ HIGH PRIORITY FIXES (Do Next)
4. Add Rate Limiting
Action: Implement client-side rate limiting
Location: static/shared/js/core/api-client.js
Status: β NOT IMPLEMENTED
5. Improve Error Messages
Action: Add descriptive error messages with troubleshooting tips Status: β οΈ PARTIAL (some modules have good errors, others don't)
β COMPLETED FIXES (Already Done)
- β Technical Analysis Professional - Demo data removed
- β AI Analyst - Mock data removed, error states added
- β Ticker speed reduced to 1/4 (480s)
- β Help link added to sidebar
π Verification Steps
After fixes are applied, verify:
- β
No
generateDemoOHLCVfunction exists in codebase - β All polling intervals are β₯ 20 seconds
- β
No direct
api.binance.comorapi.coingecko.comcalls from frontend - β Error states show when all APIs fail (no fake data)
- β Console shows warnings for failed API calls (not errors)
π― Success Criteria
- Zero mock/demo data generation
- All polling intervals β₯ 20 seconds
- Zero direct external API calls from frontend
- All error states show proper messages
- No CORS errors in console
- No timeout errors from aggressive polling
