When running with live data and in trade sim mode, is the execution of simulated trades subject to a delay that is based on the current round-trip-time to the SC servers?

E.g. if RTT=80ms, this means market data arrives with 40ms delay. A real trade would have 40ms delay minimum. Does the trade simulation account for that, such that it waits 40ms and calculates the execution price based on what the received market data is after that delay?

There is no built-in delay when using the built-in simulation mode in Sierra Chart. Refer to the following for how orders are filled in the built-in Simulation mode:
Trade Simulation: How Orders are Filled

If you want a system that will give you more realistic fills, then use our "Simulated Futures Trading Service", which uses one of our servers to process the orders, so it will have a built-in time delay due to the orders being sent over the Internet. Refer to the following:

For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
