I already run a live Polymarket trading bot, but the copy-trading logic it’s built on has lost its edge. The goal now is to transform it into a true market-making engine that delivers consistently profitable, highly accurate trades. Priority focus • Trade accuracy: every quote and fill must match the intended price and size—no more slippage-ridden or mis-routed orders. • Robustness: the system has to survive network hiccups, API quirks, and unusual market states without manual babysitting. • Code quality: modular structure, clear documentation, unit tests, and straightforward scalability for future strategy tweaks. Scope of work 1. Audit the current codebase to pinpoint weaknesses in pricing logic, risk checks, and error handling. 2. Design and implement a market-making strategy tailored to Polymarket’s order-book micro-structure, including dynamic spreads, inventory management, and quote refresh logic. 3. Refactor or extend the bot so components are cleanly separated and easy to maintain. 4. Add comprehensive logging, alerting, and graceful recovery routines. 5. Prove the upgrade with historical back-tests and a forward test on a small live stake; accuracy of executed prices versus theoretical quotes is the key acceptance criterion. The stack is flexible as long as it interfaces cleanly with the Polymarket API and runs headlessly on a Linux VPS. Deliver the full source, a requirements file, and a concise README that spins the bot up in one command. Demonstrable experience with market-making or arbitrage bots on prediction markets or DEXs will be highly valued.

Transforming the existing copy-trading bot into a reliable Polymarket market-making engine requires more than changing the entry logic. I’ll first audit the current pricing, order routing, risk checks, API usage, and recovery behavior, then map theoretical quotes against actual fills to identify slippage and mis-routing. I’ll implement a modular Python service around Polymarket’s CLOB API, separating market-data ingestion, pricing, inventory/risk management, order execution, persistence, and monitoring. The strategy will support dynamic bid/ask spreads based on book depth and volatility, inventory-aware quoting, minimum edge checks, stale-quote cancellation, quote refresh controls, and exact price/size validation before submission. Idempotent client order IDs, retry/backoff handling, reconciliation, WebSocket/REST fallback, and safe shutdown routines will help the bot handle network failures and unusual market states without manual babysitting. I’ll add structured logs, actionable alerts, unit tests for pricing/risk/execution, historical back-tests, and a small-stake forward-test report focused on theoretical-versus-executed prices. You’ll receive the complete source, requirements file, concise README, and one-command Linux VPS startup. My 10+ years building APIs, automation, and trading-style systems support a clean, scalable refactor. Would you prefer the one-command Linux VPS startup to use Docker? Muhammad Saad

Hi, Accuracy on Polymarket comes down to how you handle the order book, not just the strategy. Before touching the market-making logic, I'd want to see where the current bot leaks: are the mis-routed orders coming from stale quotes, latency between signal and submit, or partial fills against thin books? That distinction changes the whole refactor. I've built automation and API-heavy Python services that run headless on Linux VPS with logging, alerting, and recovery baked in, plus clean modular code and tests. One relevant piece: BD Automation: internal AI-driven workflow engine on Laravel and DigitalOcean. Since you have live code already, share the repo and I'll do a short audit of the pricing and error paths first, so we start on a milestone against real findings. What API tier are you on now? Adil

Being the head of Web Crest, a company known for delivering scalable and secure software solutions, I am Mubeen, offering my translation skills to your project. My team and I have vast experience in creating efficient AI-powered trading bots that understand market micro-structure dynamics. These creations deliver high accuracy and consistent profitability while surviving network hiccups, API quirks, and unusual market states, much like what you are looking for. I see your priorities lie in accurate trades, robustness, and smooth code functionality which are foundations we never compromise on. We will start by conducting a comprehensive audit of your existing codebase to address weaknesses in pricing logic, risk checks, and error handling. We will then move on to designing and implementing market-making strategy components specific to Polymarket with dynamic spreads, inventory management, and quote refresh features. Code modularity for future tweaking won't be forgotten either. Lastly, we offer not just the final product but also comprehensive documentation illustrating how to spin up the bot using concise instructions within README files and proven results from back-testing using historical data.

I have gone through your specific requirement for converting your live Polymarket copy-trading bot into a true market-making engine, and I understand that execution accuracy — filled price versus theoretical quote — is your real acceptance criterion, not just profitability on paper. Most developers will bolt a spread on top of your existing loop; I would audit the pricing and risk layers first, then rebuild around dynamic spreads, inventory-aware quoting, disciplined quote refresh and idempotent order routing, with proper logging, alerting and graceful recovery so it runs unattended on your VPS — backed by back-tests and a small forward test before you scale a single dollar.

Hi, I can audit and refactor the existing Polymarket bot into a more robust market-making engine with cleaner pricing, risk controls, logging, and recovery logic. I would not promise consistent profitability, but I can build a testable system where quote placement, fills, inventory, and slippage are measured precisely. I’d start by reviewing the current order flow, API calls, pricing model, copy-trading remnants, position/risk limits, retry behavior, and failure cases. Then I’d separate the bot into modules: market data, strategy, pricing/spread logic, inventory management, execution, risk, persistence, alerts, and monitoring. For market-making, I’d implement dynamic spread control, quote refresh/cancel rules, inventory skew, max exposure limits, stale-order protection, partial-fill handling, and reconciliation between local state and Polymarket state. I’d add structured logs, alerts, unit tests, backtest/simulation support, and a small-stake forward-test procedure comparing intended quote price/size against actual executed fills. Deliverables would include full source, requirements file, README, test notes, and deployment steps for a Linux VPS. Question 1: What is the current bot written in: Python, Node, Rust, or another stack? Question 2: Do you already store order-book/fill history for backtesting, or should historical data collection be added first? Regards, Houssame

Hello, I reviewed your requirements carefully and understand that the objective isn't simply improving the existing bot—it's replacing the current copy-trading logic with a robust market-making engine that delivers accurate execution, resilient operation, and a maintainable architecture. My approach is to first audit the existing codebase, identifying weaknesses in pricing, inventory management, risk controls, order lifecycle, and error handling. I'll then implement a modular market-making strategy featuring dynamic spread calculation, inventory-aware quoting, quote refresh/cancellation logic, position limits, and robust recovery from API/network failures. The bot will include structured logging, configurable alerts, unit tests, and backtesting to validate execution quality before a controlled live rollout on a small stake. One technical question: Does your current bot already maintain a local order book with WebSocket updates, or is it relying solely on REST polling? This will significantly influence quote accuracy and refresh latency. I can start immediately and deliver the project in well-defined milestones, including the full source code, requirements file, one-command deployment, and concise documentation. The quoted price is an initial estimate and can be adjusted after reviewing the existing codebase. Best Regards
