Since we have a little time before market open, why don't you try disconnecting from live data and reconnecting to market replay data. I've done a lot of different things today but I think I got the crash when I connected to market replay data in NT7.
The other 2 custom bar types I have are SBSRenko and NoGapRange bars.
SBSRenko is listed as bartype Custom6
NoGapRange is listed as bartype Final2
MedianRenko is listed as bartype Final3
So they don't seem to be interfering in that way.
Let me know if MedianRenko continues to work for you in NT7 (even in market replay).
Let me clarify what I mean when I said "NT" crashed. I mean that it told me that an error had occured and it needed to shut down. When I restarted, it loaded all of my other charts except for the MR chart. When I closed that chart and deleted the MR bar type from the bin/custom/type folder, then everything worked fine. I didn't want to imply by "crash" that somehow it had totally hosed up my NT7.
I'm running both MedianRenko and Minute ( 2 charts, side-by-side) now in Market Replay for May 3, 2010 (YM). Both appear to be operating fine. I can't confirm, since I don't have SBSRenko or NoGapRange installed, but would suspect it's one of the other bar types.
The only non-NT7 provided bar type I've installed is MedianRenko. You might try getting rid of the others, then adding one at a time back in, and then repeating the process until you find the culprit.
After all, it's what you learn AFTER you know it all, that counts!
I just tested the MR that Rjay posted. I tested a 2 MR bar chart next to a 1 min chart - both chart using CMI pivots. I tested them using CL 07-10.
In NT6.5, my MR charts and my NoGapRange charts had inaccurate pivots because the last bar of the day didn't necessarily end right at the session close which created an inaccurate "prior day close" which in turn created an inaccurate pivot.
NT7 changed something which causes the prior day close on the RNG bars and the SBS bars to be accurate. I've been told that NT7 cuts off the last bar of the day at the close of the session. That has worked great in NT7 for RNG and SBS.
However, I just tested MR bars and they are not cutting off at the session close so the pivots are inaccurate.. at least on my CL 07-10 charts.
This may not matter to those who don't use pivots but unless someone can fix this issue, I won't be able to use the MB bars in NT7.
I'll keep testing them on other instruments.
I like the MR bars best but I can't have them creating inaccurate pivots on my charts.
Can someone modify these bars to truncate at the session close?
edit - I just tested the MR bars on ES 06-10 and the prior day close, prior day high and low were very close to the 1 minute ES chart. Don't know if that CL issue is because of some CL data issues or what. With CL, there was one day last week when the 1 minute chart had a totally different prior day high than the MR bar chart.
