When the Algo SE server is restarted, all algos marked as persisted are loaded and made available for use. Algos that were not tagged as persistent when the algo was deployed will not be available and will need to be re-deployed.
The following tables describes what happens to algo parent orders and their related child orders when X_TRADER loses connectivity to the Algo SE server.
Note: See the TT Algo Strategy Engine System Administration Manual for a complete list of scenarios.
|Scenario||Action taken to parent order||Action taken to child orders|
Algo SE is stopped normally.
Algo SE takes the following actions to child orders for which the corresponding TT Gateway is available:
X_TRADER detects loss of connectivity to Algo SE while algo instance owner is connected to server.
X_TRADER deletes all non-ASE orders if either of the following are true:
X_TRADER deletes all ASE child orders if Client disconnect Action is set to either Pause or Delete.
X_TRADER exits normally.
Tip: The Algo SE server always cancels running algos whose input parameters contain Excel links.
