The MinVol OMA is an Order Management Algo (OMA) that lets you specify a minimum quantity required at a price level to work an exchange order. The algo will cancel the order if the volume drops below the minimum quantity. If the volume builds back up to the required quantity, the algo will re-submit the order. You can also specify the maximum number of times the algo will submit an exchange order.

Monitoring the requote count

As the available quantity at the selected price level fluctuates, the MinVol OMA will delete and resubmit orders until the order is filled or until the number of times the algo resubmitted the child order reaches the specified maximum. You can monitor the number of times the MinVol OMA has sumbitted its child order from the Algo Dashboard. The MinVol OMA displays the infomration in the RequoteCount column, as shown.

Canceling MinVol parent orders

If you cancel the parent order of an MinVol parent order, the parent order is deleted and:

• Child orders added from existing orders will remain working in market.
• Child orders added as new orders will be deleted.

MinVol OMA parameters

The MinVol OMA uses the following parameters:

• Min Qty: Minimum quantity that must be available at the price level to work the child order. When the available quantity drops below this value, the MinVol algo cancels the order,
• Requote Max: Maximum number of times the MinVol algo will resubmit its child order. When this value is reached, the algo is suspended.
• Ignore Market State: Whether to ignore the market state when submitting the parent MinVol OMA.
• Instance name: Optional name for this algo instance.
• Co-location: Location of the Algo Server to run this algo.
  The Co-location drop down is seeded based on the market of the default instrument in the selected algo. It will also seed when multiple instruments are defined if all instruments are from the same market.
• Disconnect action: Action to take if the client loses its connection to TT:
  • Leave to allow the algo to continue running normally.
  • Pause to suspend the algo until you manually restart it.
  • Cancel to delete the algo.
