During hi volatility, my computer lag!!!
Impossible to take position ...
I have cpu 2gigashertz bought in 2007 with (4*2gigas)of 800mhz memory... It is not sufficient i think
8 gigas hertz
My internet connection: 12 mégas with 30 ms ( ping): not so bad...
If i bought a new computer e5-2670 v3 xéon with 32 gigas:
Will it change something?
Anybody in my situation?
I have 3 laptop with 3 graphs with 15 indicators each which come from BT Website.
Ty/is it bécause of the lack of cpu powerful or bécause of my internet connection speed (ping)?
Depending of the indicators coding quality, bar type used, COBC or not, 15 indicators can be way too much, whatever the CPU type.
I doubt you have 30 ms from your your data feed provider, unless it's in Europe. An high latency has nothing to do with freeze, you'll only receive the price data late.
Check with a Perfomance Monitor where the problem first: CPU usage by NinjaTrader.exe, disk queue and latency, overhall memory usage, ...

The following user says Thank You to sam028 for this post:
Ty very Much
It is a such quickly response!!!!!
(I dont Know if This sentence is correct...)
I have tested my ping on a Website googling "test adsl", something like that. But i ignore the server used...
Lag=late so i have not used the good Word to explain What it has happened!!!
During high volatility like 2 days ago (not really very often), i dont Remember the last time before this week...
It was as if my computer was blocked, and 3 secondes later, 70 ticks at the same time!!!!!!!!!!!!!!!
To explain What happened : my cursor looks like hourglass or eggtimer in english, in french it is "sablier"...
My computer calculate, think....
During 5 secondes - 50 tifs at the same time - normal feed - block during 4 secondes - 20 ticks - normal feed....
About cpu ninjatrader usage, windows shows 56%, bécause i have two cores but nt7 manages only one core (except during backtesting...)
My cpu is busy, it is My opinion.
And 3.5 gigas of memory (i have 8 gigas)
My cpu seems to be busy bécause it is old and the fréquency is not High: 800Mhz
Nowadays, a computer uses 2133Mhz memory.........
Is it correct'?
Have u understood?
I hope so!

YES, anybody running NT7 suffers from lag. NT7 was designed in the rock-age of CPUs (one CPU, one core). It assumes it has the entire core to work with, and this is NOT realistic in today's computing environment. If you have 4 cores and 8 threads, it will use one of the cores or one of the threads, whichever is smallest. So if you have 8 threads, go to the bios and disable them, so it can at least use one of the 4 cores. More memory does not help because it is not the problem. I still have huge lags. Also, there are times when only restarting the entire system will help a "laggy day." Been like this for 2 years now.
NT8 is a broken promise and a broken record (it has been in the making for 3 years now). It may never happen. A "build" is nowhere to be seen, even less an Alpha or Beta version. So just suffer quietly and wait your turn on NT8 or go to another trading app. like Multi-Charts.
Yes 800 Mega-Hz is very slow so you are compounding the problem. An old Intel Core 2 Duo (2008 vintage) would be around 2.66 Giga-Hz. Are you sure you Core speed is correct?
If all is correct at your end, the answer is Yes.
Memory speed has little to do with your machine performance. and NT7 LOVES single dual cpus. so you should be Okay.
The problem could be with you datafeed. who is your datafeed? and did you run an internet test?
