Testing Trading Systems Against Bad Data and Wild Markets
Feeds glitch, ticks arrive out of order, and prices sometimes lie. Proper testing trading systems means feeding them exactly that kind of chaos on purpose. Malformed data, stale quotes and absurd swings all get thrown at the system in rehearsal. How it responds gets observed, measured and fixed. Real turbulence then arrives to find a system that has seen it all before. The system has already handled every kind of wild trading day. That's the resilience, firms are shortlisting QASource for.
