  1. Fat Finger Checks - These limits are entirely unrelated to the overall position. They either enforce properties of a single order/execution (single limit), or measure some side-channel effect (submission rate).
  2. Tranched Limits - These limits encompass only some defined subset of the overall position, providing fine-grained control:
    1. Pending limit
    2. Currency-exposure limits
    3. DSL
  3. Credit Limits - The following limits accumulate over the entire position, emits an ordering (required for de-escalation mode) and maps to a well known notion of risk. Every pool of risk must choose one of them as its primary measure of risk:
    1. Downside limit
    2. Upside limit
    3. Exposure
    4. Displacement
  4. Daily Credit Limits - Just like credit limits, but divided by settlement date.
  5. Counterparty Credit Limits - Just like credit limits, but divided by settlement counterparty.
