I have a live Python script that pulls real-time level-2 data, processes it, and fires trading signals to my platform through a websocket. The code logic itself is solid, but the socket drops randomly throughout the day, interrupting order flow. I need a robust fix that keeps the connection alive, gracefully reconnects when the exchange hiccups, and guarantees that no signals are missed or duplicated on the trading platform. Here is what I’m looking for: • Diagnose why the websocket disconnects (it shows “Connection drops” at irregular intervals) and harden the client—heartbeat messaging, exponential back-off, or whatever best practice you prefer. • Preserve my existing RL level-2 tracking code; only the transport layer needs rework. • Push the cleaned signals straight to my trading platform API—or, if it’s cleaner, through TradersPost—but absolutely no PineScript in the flow. • Package and deploy: containerise the final solution so I can spin it up on my VPS with a single command, complete with unit tests or logging that prove missed messages are zero. Acceptance criteria – The socket stays connected 24 h in a staging run, auto-rejoining within 2 s of any forced drop. – All emitted signals arrive in chronological order on the trading platform, confirmed through API logs. – Deployment steps are scripted (Docker or equivalent) and documented. The current stack is Python 3.11, asyncio, and the websockets library, but I’m open to switching to aiohttp, FastAPI WebSocket routes, or similar if it increases reliability. If you have deep experience keeping high-frequency market feeds alive, let’s get this running smoothly.

Hi I can harden your Python 3.11 asyncio websocket transport layer while preserving your existing RL level-2 tracking and signal-generation logic. The main technical issue is not the strategy code, but unreliable stream handling, missing heartbeat recovery, weak reconnect logic, and lack of idempotent delivery controls. My approach is to isolate the websocket client, add heartbeat/ping monitoring, exponential backoff, forced reconnect handling, sequence tracking, persistent logging, and ordered signal dispatch. To prevent missed or duplicated signals, I can add a local queue, message IDs, replay-safe delivery, deduplication, and API acknowledgement checks before marking signals as delivered. I can push signals directly to your trading platform API or through TradersPost if that gives cleaner delivery and audit logs. The final setup can be Dockerized for VPS deployment with structured logs, health checks, restart policies, and tests for disconnect and reconnect scenarios. This fits well with a reliability-focused market data transport fix where the goal is stable 24-hour operation and clean order-flow continuity. Thanks, Hercules

Hi there, I’ve built production-level trading systems that handle multiple exchanges and manage thousands of trades daily. I understand the critical nature of reliable websockets and have implemented solutions like heartbeat messaging and automatic reconnections to ensure continuous data flow. For your project, I’d start by analyzing the existing websocket code to identify the root cause of disconnections. I’d then enhance the client with robust reconnection logic and ensure that all signals are processed accurately, without duplicates. We can also integrate a dedicated signal processing microservice that can be independently scaled based on demand, ensuring that your trading logic remains unaffected by external factors. Let’s schedule a 10-minute call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

Websocket connections for level-2 data are notorious for silent drops and memory leaks, especially with Python's GIL when processing high-frequency feeds. The issue is usually not the script itself, but how the process is managed and restarted. I've built high-scale systems for fintech and crypto, including a lead role at Coinread where I managed 20+ microservices. I'm used to the pressure of real-time data where a few seconds of downtime means missed trades. I'll stabilize this by implementing a robust supervisor process and optimizing the event loop to ensure the script recovers instantly from network hiccups without losing state. Do you have a monitoring tool in place to alert you when the feed drops, or are you finding out after the fact?

Hi there, I understand you have a live Python 3.11 asyncio system that processes Level 2 market data and sends trading signals via websocket, but you’re facing random connection drops that interrupt order flow. Your core logic is stable, and the issue is strictly in the transport/reliability layer. My approach will focus on rebuilding the websocket layer with proven reliability patterns. First, I will instrument the current client to identify the exact cause of disconnects (heartbeat timeout, idle connection limits, or network interruptions). Then I will implement a resilient connection manager with proper ping/heartbeat handling and exponential backoff reconnection, ensuring automatic recovery within ~1–2 seconds of any drop. To guarantee no missed or duplicated signals, I will introduce a buffered outbound queue with replay on reconnect, plus sequencing/idempotency logic (based on timestamps or message IDs if available). This ensures ordered delivery to your trading API or TradersPost, without PineScript involvement. I will isolate the transport into a dedicated async module (aiohttp or improved websockets client), keeping your RL logic untouched. Does your feed include message IDs or timestamps we can use for strict ordering and deduplication? I’m ready to start immediately. Warm Regards, Aneesa.

Hi there, Your websocket drops and irregular connection losses are interrupting order flow, and I can harden that transport layer without touching your RL level-2 logic. I’ve spent the last 4 years solving exactly this kind of real-time Python streaming problem, including stabilizing market-feed clients and building reconnect-safe delivery paths that preserve ordering. The main risk here is not the disconnect itself, but duplicate or missing signals after reconnects. I’ll isolate the websocket layer, add heartbeat and exponential backoff handling, and introduce idempotent signal delivery so the trading platform receives each event once and in sequence. I’ll keep your existing asyncio processing intact and only rework the transport, retry, and handoff path. I’ll package it in Docker with clean startup scripts, structured logging, and tests that simulate forced drops and verify reconnect timing and message continuity. I’ll also document the deployment steps so you can spin it up on your VPS with one command. Best regards, John allen.

Hi, The websocket drop is the real issue here, not the signal logic. I’d leave your RL level-2 tracking alone and rebuild the transport around reconnect safety, ordering, and idempotent delivery. I’ve worked on Python asyncio services that keep market feeds and trading API calls running under ugly network conditions. - Add heartbeat / ping handling and detect stale reads fast - Reconnect with backoff, but force recovery inside your 2 second target - Add a small signal buffer with sequence IDs so sends are ordered and not duplicated - Log every inbound tick, emitted signal, API response, and reconnect event - Containerise it with a simple Docker run path and staging test mode The duplicate-signal part is usually where these systems get messy, so I’d test forced drops hard before handing it back. I can start right away and focus first on proving the 24 h staging run. Which exchange websocket and trading platform API are you using, and do signals already have unique IDs or timestamps we can use for deduping? Thanks, Slavko

Hi there, Thank you for outlining your project requirements so clearly. We at Demivision LLC specialize in building and maintaining robust, low-latency trading infrastructure, and we understand how crucial it is for real-time level-2 feeds to remain uninterrupted and reliable throughout market hours. Your description suggests that the core signal logic is sound, and the main pain point lies in the websocket’s resilience and message delivery guarantees. We have extensive experience working with Python asyncio, websockets, and fast event-driven architectures for trading systems. Our team has tackled similar challenges—implementing robust heartbeat and reconnection strategies, ensuring exactly-once signal delivery, and containerizing deployments for rapid scaling and redeployment. Our approach would start with a thorough diagnosis of the current websocket drop patterns, including network stability, exchange-side rate limits, and existing client-side reconnection logic. We’d then harden the transport layer using best practices: persistent heartbeats, exponential back-off for reconnects, and rigorous message sequencing to prevent signal loss or duplication. If it adds reliability, we can migrate the websocket layer to aiohttp or FastAPI, ensuring full compatibility with your RL code. For deployment, we’ll package the solution in a Docker container, complete with automated health checks, structured logging, and unit/integration tests to prove zero missed messages under forced disconnect scenarios. Comprehensive documentation will walk you through spinning up and monitoring the container on your VPS. We are passionate about robust trading infrastructure and would love to help you achieve bulletproof connectivity for your signals. Let’s ensure your platform operates seamlessly, no matter the market conditions. Looking forward to collaborating with you on this!

Hi, I can help harden your Python websocket transport layer while preserving the existing RL level 2 tracking and signal logic. This is a reliability problem, so I would focus on connection lifecycle, message ordering, deduplication, retry behavior, and deployment stability rather than rewriting the strategy. My approach would be to diagnose disconnect causes from logs, then implement heartbeat checks, timeout handling, exponential backoff, fast reconnect, sequence tracking, idempotent signal delivery, structured logging, and a queue based buffer so signals are not missed or duplicated during exchange hiccups. I can also review whether the current websockets library is sufficient or whether aiohttp or another async client would provide better resilience. For delivery, I can containerize the solution with Docker, add health checks, environment based configuration, clear deployment steps for your VPS, and tests or staging logs proving chronological delivery and reconnect behavior. I can also integrate directly with your trading platform API or TradersPost if that is cleaner. Best, Justin

Hi, just reviewed your setup. Websocket disconnects in live trading scripts almost always come down to missing reconnection logic and no crash recovery at the process level. I've stabilized similar Python data pipelines before and know exactly where these failure points hide. I'll audit your existing script for uncaught exceptions and dropped connection handling, add exponential backoff reconnection so it recovers automatically from feed interruptions, wrap it in Docker with proper health checks and restart policies, configure a systemd service on Linux for process-level resilience, and add structured logging so you can see exactly when reconnects happen and whether your signals are firing on time.
