I would like to know if anyone has any knowledge or experience with NT7 file structure. I am trying to track down a latency issue and would like to monitor NT to determine where this delay may be.

Is there a file on Windows that is accessed or modified when an indicator is updated ?

Many thanks for any help.

How much lag is there in your opinion ?
What are you trying to do / measure ?

The file system has its own latency, if the file is written and not flushed, you will measure an additional delay, that may not be what you are looking for.

1. What is your data provider ?
2. Drawing is event driven and might not update
3. What is the % load on your CPU (other resources ? network & file system)

You can alternatively look to a measurement like explained here (somebody made an indicator for that):

NinjaTrader Support Forum - View Single Post - ZenFire lag

This will measure the time stamp of the data with your machine.

There are also a few threads on NexusFi
Too often lagging is due to exceptional unefficient/badly coded indicators bringing your system down;
