The cost of building a profitable arbitrage trading bot depends on the complexity of the development process, which includes designing a statistical arbitrage strategy, choosing the right infrastructure, integrating with multiple exchanges, programming using optimal languages and frameworks, thoroughly testing, and ongoing maintenance.

A sound statistical arbitrage strategy is key to profitability, requiring research and backtesting. Supporting multiple exchanges and currency pairs identifies more opportunities. The bot needs to be fast enough to capitalize on fleeting mispricings. Choosing the right programming language and frameworks ensures efficiency.

Extensive testing in simulated environments is critical before going live to ensure profitable strategies. Ongoing monitoring and maintenance is required to maximize uptime and adapt to changing market conditions. Factors like cloud vs local infrastructure, features, and UI also impact cost.

The goal is to build a bot that can generate passive income through arbitrage. With the right development approach and optimization at each step, the investment in an arbitrage trading bot can pay off handsomely.
