API Rate Limit & Price Feed Issue for Trading Platform (Twelve Data)

@kabirchy

Hi there, I understand your trading platform is experiencing API rate limiting issues with Twelve Data causing frozen quotes and request caps. I've worked extensively with API integration and rate limiting solutions for financial platforms. My approach would be to implement a smart caching layer that stores price data locally while respecting Twelve Data's rate limits. I'll create a robust queuing system that batches requests and implements intelligent retry mechanisms. The solution will include proper error handling, fallback options, and monitoring to prevent future bottlenecks. I'll optimize your existing PHP/MySQL architecture to handle concurrent requests efficiently while maintaining data accuracy. The implementation will involve: 1. Building a local cache with automatic refresh intervals 2. Creating a request scheduler that respects API limits 3. Implementing proper error handling and logging 4. Adding monitoring dashboard for API usage tracking This will ensure your platform continues receiving real-time data without hitting rate limits. Best Regards, Khorshed Alam, RS Software

Hi, I can see the real issue here: the platform isn’t just “hitting a limit” , the quote layer is probably over-polling, duplicating requests, and starving the UI when Twelve Data slows down. I’ve fixed similar PHP/JavaScript feed bottlenecks by tracing the request path, adding lightweight caching, and tuning call frequency so charts stay responsive without burning quota. I’ll inspect the cPanel files, find the endpoints pulling Twelve Data prices, then refactor the polling logic, add sensible rate limiting, and make sure identical quotes aren’t fetched twice. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can start as soon as you grant access and should be able to isolate the bottleneck quickly. Which part of the current feed logic is most critical to preserve: chart refresh speed or quote freshness? 1) Are the prices pulled from one shared PHP endpoint or from multiple JavaScript widgets? 2) Do you want caching at the server layer, browser layer, or both for best stability? 3) Should I preserve the current chart refresh timing exactly, or adjust it slightly to stay below vendor caps? Looking forward to your reply so we can finalize the exact plan. Thanks, Asad

The real cause of your quota blowout is almost always that each visitor's browser polls Twelve Data directly, so ten users watching the same symbol means ten times the calls — the fix is to make the server the single source of truth. I'd add a short-lived server-side cache (a few seconds per symbol) so identical quotes are fetched once and every visitor reads from that cache, which alone usually collapses your request volume dramatically. Then I'd batch multiple symbols into single endpoint calls where the API allows, apply a rate limiter to all outbound requests, and tune the refresh intervals so tickers and charts still feel real-time while staying safely under the vendor cap. If your plan includes it, I'd move the fast-moving quotes to Twelve Data's WebSocket feed, which pushes updates instead of polling and is far more quota-friendly. I'll verify by watching the request count across a simulated trading day to confirm zero freezes. Experienced with REST and WS market feeds — give me cPanel access and I can start diagnosing right away.

22 years of experience in PHP/MYSQL and i can fix your API issue which you think is simple may have some issue regarding the freeze of the API request and response. Let me check the code and API documentation and fix the issue thanks.

@VirasatSolutions

Greetings, our company has accumulated **15 years of experience** working with PHP JavaScript integrating APIs, REST/WS market feeds, MySQL, and creating performance-oriented web applications. We are ready to examine your current integration with Twelve Data to uncover potential over-polling. Phase of the project: audit: Determine each Twelve Data call and pattern of polling chart ticker, duplicate calls. *Caching: use both server & client-side minimal caching to avoid repeat quote requests. Rate Limiting: create a single throttling and queuing mechanism for the raising calls. *Smart Polling: Adjust the frequency of polls as the endpoints while still preserving a live-like experience. *Data Optimization: Eliminate duplicated symbols and aggregate requests as much as possible. Reliability: Introduce timeout retry fallback, and error handling to prevent the situation of the frozen quotes. *Monitoring: keep the record of the API consumption and failure so that the quota consumption may be tracked. Testing: Check the charts tickers concurrent users, and normal trading workflows post-implementation. We advocate **audit centralize requests cache throttle optimize test** as a sequence of steps instead of simply raising poll intervals. We are always ready to collaborate through cPanel as well as production PHP/JavaScript code that has been frozen and is not causing functionality issues to other platform features. --ABHAY

@denisSolution

Hi, I'm Denis, a full-stack developer who has worked on systems that pull real-time market data under strict API limits. I understand the urgency—freezing prices and hitting caps can break a trading platform, and the fix usually lies in how requests are structured rather than the API itself. In your case, the Twelve Data endpoints are being queried too frequently, likely without caching or controlled spacing between calls. I’d start by auditing the scripts that hit those endpoints, then add lightweight caching (Redis or even flat files) to store recent quotes and avoid duplicate requests. Next, I’d implement a rate-limiting layer that spreads requests evenly, respecting Twelve Data’s limits while keeping the UI responsive. The PHP cron jobs or JavaScript intervals triggering these calls will be adjusted to fetch only when necessary, not on every poll. I’ve done this before with high-frequency market data feeds, where the difference between freezing charts and smooth operation came down to caching and controlled polling. The key is balancing real-time feel with strict rate limits—no overkill, just smarter request patterns. The main risk here is not properly measuring the current request volume before making changes, which could still leave you hitting limits. I’d log and monitor the rate changes during deployment to catch any miscalculations early. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

@welkinsystems

Could you please answer following queries : 1. **Twelve Data plan:** Which subscription/plan are you using and what are its API/credit limits? 2. **Data connection:** Are prices currently fetched through REST polling, WebSocket, or both? 3. **Affected areas:** Which features freeze—live ticker, charts, watchlist, trading screen, or all? 4. **Current frequency:** How often are price requests being made? 5. **Usage:** Approximately how many symbols are monitored simultaneously and how many concurrent users do you have? 6. **Architecture:** Does each user's browser call Twelve Data directly, or are requests made through a central PHP/backend service? 7. **Caching:** Is Redis, Memcached, database caching, or another server-side cache available? 8. **Errors:** Can you provide Twelve Data usage statistics and any rate-limit/HTTP 429 errors or logs? 9. **Required refresh rate:** How frequently should live prices ideally update (1 sec, 5 sec, 10 sec, etc.)? 10. **Trading dependency:** Are these prices only for display/charts, or are they also used for order execution, P&L, stop-loss, etc.? 11. **WebSocket:** If currently REST-based, are you open to using Twelve Data WebSocket for live prices?

@jayantkumar314

Hi,I can review the existing PHP/JavaScript price-fetching logic and reduce the unnecessary Twelve Data requests without changing the rest of the platform. I’ll first trace where the polling is happening, check how often the same symbols are being requested, and then add a lightweight cache and sensible request throttling so duplicate calls are avoided.I’ll also adjust the refresh intervals so the charts and tickers continue to feel live while staying safely below the API quota. Once the changes are in place, I’ll test the flow through cPanel and verify that prices continue updating smoothly over an extended session.I can start immediately and should be able to turn this around quickly once I have access to the relevant files.

@rbtech1984

Hello!! I can quickly diagnose the Twelve Data request bottleneck in your JavaScript and PHP code, then optimize polling, caching, and rate limiting so prices and charts remain smooth without exhausting the API quota. * Is the issue affecting all charts or only specific symbols? * Do you know your current Twelve Data plan and request limits? * Can you provide the cPanel access immediately after the milestone starts? The fix will include locating every Twelve Data request, removing duplicate calls, adding lightweight caching, applying safe request throttling, and tuning intervals for reliable near-real-time updates. Relevant market data API and trading platform integrations have been completed with strong focus on performance and stability. Ready to inspect the current implementation and resolve the freezing issue quickly in chat. Best regards Farhin B

@waqaswebmaster

I can trace the Twelve Data request flow through the existing JavaScript/PHP code and fix the polling bottleneck without disrupting the trading interface. I’ll identify duplicate and excessive requests, add lightweight quote caching, enforce rate limiting across outbound calls, and rebalance polling intervals so the feed stays responsive while remaining safely within the provider’s limits. I’ll test the updated flow through normal trading activity to verify that quotes and charts remain stable without unnecessary API consumption. Waqas Ahmed

Hi, I can quickly audit and refactor the JavaScript/PHP price-fetching logic causing the Twelve Data request-limit issue. I have **10+ years of experience with PHP, JavaScript, APIs, AJAX, REST/WebSocket integrations, caching, and performance optimization**, including real-time data-driven applications. ### What I’ll do * Locate all Twelve Data API calls across the PHP/JS codebase. * Identify duplicate requests, excessive polling, and inefficient chart/ticker refresh logic. * Add lightweight caching so identical quotes are reused instead of repeatedly requested. * Implement centralized **rate limiting/throttling** for outbound requests. * Optimize polling intervals based on the required display frequency. * Where appropriate, consolidate requests for multiple symbols instead of making individual calls. * Review error handling and API-limit responses so temporary limits don't freeze the UI. * Ensure charts and live prices remain responsive while staying safely within the provider's limits. * Test the changes through normal trading-day usage and monitor request behavior. I’ll make the changes carefully through cPanel and preserve the existing trading functionality. I can also add logging so you can see request frequency, cache hits, API errors, and rate-limit events. **Estimated timeline:** 1–3 days I’m available to start immediately and can first perform a quick code audit to identify the exact bottleneck before making production changes.
