Boss Battle: Bug King
Storyโ As you approach the Bug King's fortress, your trading bot's logs begin to flicker with warnings. The market data feed grows erratic, order executions fail without reason, and your position sizes seem to multiply uncontrollably. This is the Bug King's domain - where logic breaks and trading systems crumble.
The Bug King emerges from the digital depths when trading systems grow complacent, feeding on untested code and overlooked edge cases. Legends speak of traders who vanished overnight when their bots encountered the Bug King's realm of infinite slippage and cascading failures.
Mind Note
โThe most dangerous bugs are the ones you don't know exist.โ
Lesson Content
In the Bug King boss battle, you'll face complex algorithmic trading challenges that test your ability to build robust trading systems. The Bug King represents the most insidious trading bugs that can destroy your capital - latency issues, API failures, logic errors, and market data inconsistencies. Your task is to develop a multi-layered trading bot for the Indian markets using the Zerodha Kite API that can handle these challenges. You'll need to implement proper error handling, connection resilience, and market data validation. For example, when trading Nifty 50 futures, your bot must account for exchange holidays, circuit filters, and unusual market conditions. You'll create a system that monitors execution quality, tracks slippage, and maintains position sizing discipline even during volatile market sessions like those seen during the 2020 COVID crash or the 2023 Budget announcement.
