Connection to Ninjatrader historical market data server lost. The process cannot access the file.last.ntd because it is used by another process.
When I get this I cannot get the chart up for the relevant instrument in this case TF, even repairing the database, refreshing the data and even deleting the tick data directory. Usually after a few hours I can get it to work with reboots etc which is painful. Now this hasn't happened for a couple of months and then all of a sudden it started happening again yesterday. I was thinking what did I start doing now that I was doing back then? Then I realized I started using windows process explorer again.
When I shut process explorer down and rebooted I had no problems again. So I am thinking this is the cause of this very annoying issue. For some reason process explorer is using the data.
The purpose of this post is twofold.
1. Firstly if others have had the same problem try shutting down process explorer.
2. Does anyone at ninja know why this would be the case? I quite like process explorer so would like to keep using it when I use ninja.
I will monitor this issue as it is possible that it is not process explorer at all but I remember that I started to get these problems last time when I started to use process explorer about that time as well. I will report back if I still have the issue without using process explorer.
Cheers
