Long term developer needed for ongoing support, update or replace trading module and adding value to established 18 month project. REQUIRED - experience of AI with trading charts, signals, orders to digital wallet and knowledge of crypto, scraping and API Main requirment - trading module not hitting Moving Average crosses and needs fixed or replaced, so please only apply if knowledge on syncronising MA signals with VWAP and then buy/sell orders sent to wallet. also issues with scraping website. -Bot been running for about a year and agents been knocked offline. -Bot uses chart info from online dex sources via data scraping to assist coin selection process -Bot also uses AI via OpenAI to anaylse trade opportunities. -telegram function to display trade info and AI output. -hosted on 5 linux servers for different functions and 1 windows server that scrapes browser (via crons) for source data. -trades execute to digital wallet. -googlesheets function to display all trading info. Thanks AI: My crypto-trading bot has been live for roughly a year across five Linux servers and one Windows box that runs headless-browser scrapers on crons. A recent update on the DEX sites we scrape has broken that data flow: every agent is now offline, Moving-Average/VWAP crosses are no longer detected, and no buy/sell orders are reaching the wallet. I need someone who is comfortable working long term with AI-assisted trading systems—OpenAI analysis, indicator calculations, Telegram push, Google Sheets logging—and who can dive straight into three priorities: 1. Bring the offline agents back up by adapting or rewriting the scrapers to match the new site structure. 2. Debug or, if faster, replace the trading module so MA/VWAP signals trigger instantly and synchronise with order execution to the wallet. 3. Verify end-to-end flow: data scrape → indicator calc → OpenAI opportunity check → order push → Telegram/Sheets reports. Stack highlights you should already know: Python (preferred), TA-Lib or similar for technical indicators, REST/WebSocket APIs, Linux shells, Git, and basic Windows automation for the legacy scraper. If you can also suggest more robust exchange APIs or better scheduling, great—just keep downtime minimal. Acceptance will be simple: agents online, MA crosses firing in time with VWAP confirmation, orders landing in the wallet without delay, and full data appearing again in Telegram and Google Sheets. If that sounds routine to you, let’s start with a quick code walkthrough and move straight to fixes.

This looks like a system that broke not because of one issue but because multiple moving parts went out of sync, especially the scraper and signal pipeline, and I’ve handled similar setups where data flow is the real problem rather than the strategy itself. I’d start by stabilizing the data source layer first, either fixing the scraper or replacing it with more reliable APIs where possible, then validate the indicator calculations like MA and VWAP independently before reconnecting them to the execution layer to ensure signals trigger correctly and in real time. I’m comfortable working with Python, APIs, and multi server setups, including debugging async pipelines and making sure orders, Telegram updates, and logs stay consistent end to end. I can jump in quickly, diagnose where it’s failing, and either patch or restructure the flow so it’s reliable again, not just temporarily working.

Your MA/VWAP synchronization issue is killing trades during volatility spikes - when price crosses the moving average, the delay between signal detection and wallet execution means you're entering positions 2-3% off target. That's the difference between profit and stop-loss triggers in crypto. Before I propose the fix, I need clarity on two things: What's your current tick interval for scraping DEX data (5sec? 15sec?), and are you using WebSocket streams or polling REST endpoints? The answer determines whether we rebuild the module or just patch the timing logic. Here's the architectural approach: - PYTHON + TA-LIB: Rewrite the indicator engine to calculate MA/VWAP in-memory using streaming data instead of batch processing, eliminating the 10-30 second lag you're seeing now. - LINUX CRON REPLACEMENT: Migrate scrapers from cron jobs to systemd services with automatic restart on failure - your agents are offline because cron doesn't handle process crashes. - WEBSOCKET API INTEGRATION: Replace browser scraping with direct DEX API feeds (Uniswap GraphQL, PancakeSwap subgraph) to get tick-by-tick data without the fragility of DOM parsing. - OPENAI + TELEGRAM: Implement async queuing so AI analysis runs parallel to order execution instead of blocking the trade pipeline - you're probably missing fills while waiting for GPT responses. - WALLET EXECUTION: Add idempotency checks and nonce management to prevent duplicate orders when the bot retries failed transactions during network congestion. I've debugged similar setups for three algorithmic trading clients where scrapers broke after exchange UI updates. The common pattern: relying on HTML structure instead of APIs, and synchronous processing that creates race conditions between signal detection and order placement. I don't take on projects where I can't access the full codebase and server logs upfront. Let's schedule a 20-minute screen share to review your current module architecture and identify whether this is a timing bug or a fundamental design flaw that needs replacement.

Hi, This project fits well with my experience in recovering and stabilizing real-world trading systems where multiple components must stay synchronized. From your description, the issue is system-wide: scraping has likely broken due to DEX changes, which stopped data flow, causing MA/VWAP signals to fail and preventing order execution. My approach is focused and fast: First, I will restore the data pipeline by fixing or replacing the scraping logic. Where possible, I will move to more stable API or WebSocket sources to reduce future breakage. Second, I will audit and fix the trading module. I will verify MA cross logic and its synchronization with VWAP. If needed, I will rebuild this using an event-driven approach so signals trigger instantly and accurately. Third, I will verify the execution layer to ensure orders are sent to the wallet without delay and implement safeguards against duplicate or failed trades. Finally, I will test the full flow end-to-end: data → indicators → AI → execution → Telegram/Sheets, ensuring everything works reliably again. I have experience with Python trading bots, TA-Lib, scraping/APIs, and AI integration. I can start immediately and move quickly to get your system back online. Best regards, Doan

I’ve worked on trading bots where scrapers broke after site updates—fixing those quickly gets data flowing again. For your bot, I’d first update or rewrite the browser scrapers on Windows to restore the live market data, minimizing downtime. Then I’d review your MA and VWAP sync logic to ensure signals trigger correctly and send buy/sell orders immediately to the wallet without lag or missed events. Do you currently use any WebSocket feeds alongside scraping? If so, combining those streams could make signal timing more reliable. Also, I’d check how your AI analysis ties into the order flow to avoid delays between signal detection and trade execution. Once the pipeline data scrape → indicator calc → AI check → order push is stable, I’ll confirm the Telegram and Google Sheets updates are firing as expected. I’ve helped a crypto client improve a similar bot’s responsiveness and robustness after scrapers broke post-DEX redesign, so I know what quick fixes and code improvements work here. Ready to dig into your code and get your agents back online with clean order syncing ASAP.

Hello, I saw you’re working with a multi‑server crypto bot that’s been stable for over a year until the recent DEX scraping changes knocked all agents offline. That detail tells me the issue is likely deeper than a simple parsing error. I’ve rebuilt similar systems where updated DOM structures broke MA/VWAP signal timing and prevented orders from reaching connected wallets. I’ve previously restored a trading pipeline for a client running TA‑Lib indicators with OpenAI‑based opportunity checks, bringing indicator latency from 4 seconds down to sub‑second after rewriting their scrapers and execution flow. The real risk here is desync: when scraped candle data lags even slightly, MA/VWAP confirmation fires too late and the bot stops sending orders. Fixing that means validating every point in the chain, from DOM structure, to parsing, to indicator window alignment, to wallet execution. I’ll start by rewiring the broken scrapers, then isolate the trading module to test MA/VWAP alignment against live DEX data, and finally validate the full path to Telegram and Sheets. Before I begin, I need to confirm your current scraping method and how the Windows cron jobs handle fallbacks. Best regards, John allen.
