Price Limits Message Fields
The Price Limits message can be sent as a sequenced or un-sequenced message. As a sequenced message, it is sent out at the start of the session for products that are subject to price limits per the contract specifications. The Price Limits message does not signal whether price limits are in effect for that symbol; it simply provides those values for when they are in effect. If multiple Price Limits messages are received for the same Symbol, the most recent values will override the previous values.
As an un-sequenced message, it is sent out with a Market Snapshot message as part of the Periodic Refresh mechanism.
Price Limits messages are included in a spin response.
