Before: Every tick → Full re-render 📉 After: Ticks update price only, AI stays stable 📈 Performance lesson: WebSocket data should be isolated. Don't let real-time price updates trigger expensive AI computations! Small optimizations compound. App now feels buttery smooth.

✅ Fixed unnecessary re-renders in AI panel (websocket ticks were triggering full component tree re-render) ✅ Removed dead code & unused components ✅ Thorough functionality testing The fix? Memoized the AI component and separated tick data from analysis state:

[Day 11] Smart Invest 🎯 Performance optimization day! Fixed a critical bug where AI Explanation was re-rendering on EVERY websocket tick 😱 ✅ Optimized watchlist component performance #BuildInPublic #ReactJS #WebSockets #PerformanceMatters #100DaysOfCode #algotrade #Fintech

[Day 10] Smart Invest Transformed a cluttered AI panel into a clean tabbed interface! - AI Signals - AI Explanation - Options Flow React pattern: Keep tab state local when it doesn't need to be global. useState > Redux. #buildinginpublic #Finance #100DaysOfCode #algotrading

[Day 9] Smart Invest Today, tested AI analysis in live market data 📈 ✅ It held up under market pressure ❌ Still not fast enough ❌ UI needs some attention Speed and UX enhancements are on the way! #100DaysOfCode #algotrading #fintech

3/3 💡Options data analysis: * Max Pain calculations reveal institutional positioning * Unusual OI changes predict breakouts * PCR divergence from price shows smart money moves * ATM strike activity indicates directional bias Most retail traders ignore this edge completely.

2/3 📊 The hardest part isn't AI - it's clean, real-time data fusion: 1. NSE options chain (PCR, Max Pain, unusual OI) 2. WebSocket for live prices 3. Multi-source news + sentiment 4. FII/DII flow data 5. Technical indicators across timeframes

[Day 8] Smart Invest 1/3 🔥 Built a production AI trading system that processes real-time market data + options flow + news sentiment to generate high-conviction trading signals. #buildinginpublic #algotrading #fintech #100DaysOfCode

@codelysticX Thank you! The key breakthrough was identifying redundant useEffect calls across chart components. Consolidated 15+ hooks into 3 strategic ones. Also implemented React.memo selectively - not everywhere, just where profiling showed actual impact. Real-world testing is everything.

@sumitbopche01 Shipping a major performance update that makes smartinvest 60% faster is fantastic—optimized React rendering and efficient hooks show real engineering skill. Impressive progress!

[Day 7] building smartInvest Major performance update shipped today. The trading platform now runs 60% faster with optimized React rendering and consolidated useEffect hooks. CPU utilization has significantly reduced. #buildinginpublic #100DaysOfCode #Finance

Summary: 60% performance improvement Full mobile compatibility New portfolio features Customizable UI layout Enhanced debugging capabilities Next phase: Advanced charting indicators and automated trading features.

Technical improvements: Reduced component re-renders Optimized WebSocket connections Added performance monitoring panels Debug tools for real-time diagnostics Smart memoization throughout Clean architecture, better performance.

[Day 6] SmartInvest Spent time refactoring the Charts component. The live websocket data is rendering correctly, but the historical data from the API isn’t displaying yet. The news section is shaping up really well and proving to be very useful. #buildinpublic #100DaysOfCode

[Day 5] building SmartInvest ✨ UI polish and usability wins. Moved category selector under articles; 2‑column article grid Fixed chart overlay overlap; tighter spacing and responsiveness #buildinpublic #fintech #100DaysOfCode

@levelsio That’s the grind! 😅 Gotta keep throwing those stones. @levelsio

🍰 Only 4 out of 70+ projects I ever did made money and grew 📉 >95% of everything I ever did failed 📈 My hit rate is only about ~5% 🚀 So...ship more

Hey @cursor_ai — the “Call tool” dialog makes long JSON/commands hard to review (no wrap, small input). Details in Issue github.com/cursor/cursor/…

8/8 Read SEBI + exchange data rules: real‑time tick redistribution is a licensed activity. Republishing live feeds or “derived” analytics demands explicit permissions, disclosures, and controls. I will keep building for personal use for now.

7/8 Facade/Proxy: Next.js API routes proxy the backend for historical data, so the frontend never handles broker auth. Client services wrap Socket.IO with a tiny, consistent API. Smaller blast radius, better tests.

[Day 4] building SmartInvest ✨ 1/8 Just wrapped a deep dive on my trading app’s architecture + compliance. Solid foundations, clean abstractions, and a clear runway to scale. Notes on design patterns I’m using : #buildinginpublic #Trading #Fintech
