Poloniex–CoinEx Futures Arbitrage Bot

I am looking to automate a cross-exchange strategy between Poloniex and CoinEx futures. The core of the job is a bot that can pull real-time order-book and funding-rate data from both exchanges, detect immediate pricing gaps, and execute trades automatically to capture the spread before it closes.

Key things I need built in:
• Full hands-off trade execution driven by the exchange APIs.
• A live analytics layer that constantly recalculates spreads and trading fees so the bot never fires on a negative edge.
• Position-sizing logic to cap exposure per trade and in aggregate; the limits should be configurable from a single settings file or dashboard.

I have not locked myself into one style of arbitrage yet, so if you have strong opinions on spatial vs. triangular flows I’m all ears—as long as the final code is modular enough for me to switch logic blocks later. Python is my first choice because of its rich library support, but I will happily accept another language if you can demonstrate lower latency or cleaner maintenance.

Deliverables I expect:
1. Well-documented source code and a brief README that covers setup, environment variables, and how to add new pairs.
2. A small test suite (unit or integration) proving the core functions: data ingestion, spread calculation, order placement, and position-sizing guardrails.
3. A quick screen-share or video walkthrough showing the bot running on testnet accounts for both exchanges.

I will provide API keys once we have a working sandbox build, and I am ready to start immediately.
