I would like to move from Ninja Trader to Sierra Chart. After reading the documentation, I have to admit that the support from Sierra Chart is much better, and the learning curve of the ACSIL is deep.

Now the biggest question for me is how to implement the order callbacks in ACSIL. In ninjatrader, when the order changes status, I can hook up the call back function and update my strategy accordingly. I am wondering how to achieve this in Sierra Chart. Do I have to iterate through the whole order list and figure out what has just changed status?

If you don't get an answer here, I suggest you post the question on the SC support forum (if you haven't already) for the SC engineers to answer.
