Order feed message stream integrity

A computer readable medium having stored therein instructions executable by a processor, including instructions executable to:

• send a first data message, wherein the first data message includes data related to a topic, wherein the first data message includes a first data message sequence number with a value of a predefined initial sequence number, wherein the first data message includes a first data message phase number;
• send a first stop message, wherein the first stop message includes a stop message phase number, wherein the stop message phase number is the same as the first data message phase number, wherein the stop message indicates that no heartbeat messages will be sent after the stop message is sent and before another data message is sent;
• and
• send a second data message, wherein the second data message is sent after the first stop message, wherein the second data message includes data related to the topic, wherein the second data message includes a second data message sequence number with a value of the predefined initial sequence number, wherein the second data message includes a second data message phase number, wherein the second data message phase number is different than the first data message phase number.

A system including:

• a computing device,
• wherein the computing device is configured to send a first data message, wherein the first data message includes data related to a topic, wherein the first data message includes a first data message sequence number with a value of a predefined initial sequence number, wherein the first data message includes a first data message phase number;
• wherein the computing device is configured to send a first stop message, wherein the first stop message includes a stop message phase number, wherein the stop message phase number is the same as the first data message phase number, wherein the stop message indicates that no heartbeat messages will be sent after the stop message is sent and before another data message is sent;
• and
• wherein the computing device is configured to send a second data message, wherein the second data message is sent after the first stop message, wherein the second data message includes data related to the topic, wherein the second data message includes a second data message sequence number with a value of the predefined initial sequence number, wherein the second data message includes a second data message phase number, wherein the second data message phase number is different than the first data message phase number.
