🧵 Day 9/30 — #SystemDesign
WebSockets vs Polling: How real-time apps actually update instantly
When you receive a WhatsApp message instantly, see stock prices update live, or watch a food delivery rider move on a map, the system is using a real-time communication model. Traditional HTTP requests were not designed for constant live updates. That’s why systems choose between Polling and WebSockets.
Polling means the client repeatedly asks the server for updates after fixed intervals.
Example:
Client → “Any new messages?” every 5 seconds.
If nothing changed, the request still happened. This creates unnecessary traffic and latency. If the polling interval is long, updates feel delayed. If the interval is short, server load increases.
Polling is simple and easy to implement, but inefficient at scale.
WebSockets solve this by creating a persistent two-way connection between client and server.
Once connected:
Client ⇄ Server
Now the server can push updates instantly whenever something changes. No repeated requests are needed.
That’s why chat apps, multiplayer games, trading dashboards, and live tracking systems often use WebSockets.

🧵 Day 8/30 Of #SystemDesignSeries CDN (Content Delivery Network): Why some apps feel instant worldwide A fast backend alone doesn’t guarantee a fast user experience. If your server is in one country and users are spread globally, physical distance creates latency. Every image, CSS file, JS bundle, and video request must travel farther, which slows load times. That’s why modern systems use a CDN. A CDN is a distributed network of edge servers placed across the world. Instead of every request going to your main origin server, users fetch cached content from the nearest edge location. This drastically reduces latency and improves speed. Example: If your server is in India and a user opens your site from London, without CDN the request travels to India and back. With CDN, London users can get static assets directly from a nearby UK edge node. What CDNs usually cache: → Images → Videos → CSS / JS files → Fonts → PDFs → Static pages → Downloadable assets Why CDNs matter: → Faster page loads globally → Lower load on origin server → Reduced bandwidth costs → Better scalability during spikes → Improved uptime → Stronger DDoS protection → Better SEO (speed impacts ranking) Important concepts: Cache Hit = file already available on edge server Cache Miss = CDN fetches from origin then stores it TTL = how long content remains cached Invalidation = removing outdated cached files after updates Real companies using CDN layers: → Netflix for content delivery → Amazon for product assets → GitHub for static resources → Shopify for global storefront speed → YouTube for distributed media delivery #30DaysOfSystemDesign #CDN #BackendEngineering

@kotakneosupport Yes, my Algo would placing Buy orders using API only for Delivery of Stocks & ETFs. In that case, it would be ZERO brokerage right and not 0.2%
Please confirm once as planning to shift everything to Kotak Neo if this holds true.
English
@AJTrader24 Hello Amit, please note zero brokerage is applicable if trades are executed through the API and user is under any of the Trade Free plans. Further, you can go through the below link for complete information. Need assistance, we are just a DM away.

@kotakneosupport Noe website say Stock Delivery ₹0 delivery charges for first 30 days. 0.20% thereafter.
But, if my Algo places Buy or Sell for Stock Delivery from API, would it be FREE?

@Sahilinfra2 Hardly any actual progress visible other than barricading. Do you by any chance know what is timeline for this flyover please? It has become increasingly difficult to cross Signal especially Kids & Seniors. Does it falls under MMRDA or TMC or any other authority?

Is this the number you called from? My mobile operator is marking it as Spam & hence I choose not to pickup. Call me between 2-3pm Today please
English
@AJTrader24 We tried reaching you on your registered contact number, but the call went unanswered. DM us your available timings or an alternate contact number so our team can get in touch and assist you further.
English
@FyersSupport Does Fyers' new Automate platform allows to create Algo if we have StockMock strategies? So that it is easier to just configure with StockMock fields & can run it?
English
@AJTrader24 Hey Amit, we are looking into your concern. Allow us some time, and we will provide you with an update.
English
@FyersSupport What I meant is that can I say choose Strike at 9:20 & Place Buy Order when Option High from 9:20 to 9:25 is broken anytime during that day? Also, immediately Target-SL should be allowed to be placed in Points. Also, does it allow Trailing SL too?
English
@AJTrader24 Hey Amit, at present, you can create strategies within automate, but importing algos from external platforms is not supported. However, you have the flexibility to set up webhooks, enabling you to trigger alerts from third-party platforms.
English
@FyersSupport Yet to hear from you regarding Static IP enforcement & guidelines which are due from 1st April. How does Fyers plan to implement it, need details about it in advance, few brokers already started the process
