Other Integration Sonstiges Python MySQL JavaScript Java Sammeln von Daten im Internet SQL Data mining Linux

Spezifikation

We are looking for a developer to finish and stabilize an existing Kalshi trading bot (~60% complete) built in TypeScript.

This is not a MetaTrader EA. The system interacts with the Kalshi API and requires strong understanding of execution logic, order handling, and state management.

Scope of Work:
  • Review and understand existing TypeScript codebase
  • Complete missing functionality
  • Fix execution issues (order placement, retries, state sync)
  • Handle edge cases (partial fills, API errors, timeouts)
  • Improve reliability and stability
  • Implement proper logging and trade tracking
Key Requirement (Important):
Experience with API-based trading systems (not just MT4/MT5 EAs)

You MUST have:
  • Node.js / TypeScript experience
  • Experience working with trading APIs
  • Understanding of order lifecycle (placed → partial → filled → cancelled)
  • Experience debugging real-time systems
Do NOT apply if:
You only build MT4/MT5 indicators or EAs without API integration
You have no experience handling order state or execution logic

To Apply, answer these:
  • What trading APIs have you worked with?
  • Have you handled partial fills and order state tracking? Explain briefly
  • Describe how you prevent duplicate orders during API retries
  • Share 1 relevant project (GitHub or description)
  • Your experience with TypeScript
Availability to start

Goal:
Deliver a stable, reliable trading bot that runs without execution errors.
