Pricing Model Testing Changes

It is tempting to overfit pricing configuration for a partiular situation that arises. We can't assume changes to fit a single situation will work well in other timezones.

To test changes for one situation and their impact over a broader range of scenarios. We recommend:

Simulations

  • Simulate multi-week impact

  • Simulate multi-instrument impact

  • Observe:

    • spreads by timezone

    • predictivity of the model

    • predictivity of the signals

    • predictivity of the nodes

    • availability (how long we were not firm during a trading week)

Pre-Post Implementation Checks

  • Make the changes during the week, to avoid outages over the weekend where configuration is incorrect, but this is only discovered over the weekend.

  • Do a rolling bounce of the related processes during the day.

  • Observe the following pre-and post the change

    • spreads by timezone

    • predictivity of the model

    • predictivity of the signals

    • predictivity of the nodes

  • availability (how long we were not firm during a trading week)
