Hello,
1. RequestTimedRefresh works in Indicators only.
In AA there is "Run Every" feature that allows to re-run the AA formula automatically
2. AFL execution is quote driven (when new quote arrives then indicator executes)
+ interval refreshes (that allow you to process other things including status
messages). Implementing formula execution upon every response from TWS
would cause significant extra CPU load. I am not saying no, but it is not planned any time soon,
as querying order status can be done easier using RequestTimedRefresh
plus it gives opportunity to handle situations when TWS STOPS sending anything
(such as internet connection failure). RequestTimedRefresh
works as watch dog and allows to send say alerts to notify that something is wrong.
It is more secure than relying on TWS notification.
Best regards,
Tomasz Janeczko
