Velocity Check HIGH
Burst detection · Rolling window counter

enabled: true
severity: "HIGH"
parameters:
threshold: 5 # Max transactions before alert triggers
window: "60s" # Rolling time window for count
account_scope: "source_account" # Field used to group transactions

enabled: true
severity: "CRITICAL"
parameters:
max_miles: 500 # Maximum plausible travel distance
window: "1h" # Time window for location comparison
