Hello ,
I am Unable to download any indicator, this shows and ninja crashes every time.

Error
"Unhandled exception. Attempted to read or write protected memory.
This is often an indication that other memory is corrupt."

Does anyone has a idea on how to correct this. Platform support not finding the problem that is being going on for about 2 weeks with emails and one live support.

I have unistall and deleted all workspaces,imported indicators, tested in new ninja in safe mode( cant import on safe mode) download new ninja , new/fresh everything and Crashed again. Support says to get my IT guy, that is not ninja.

What can I do, any suggestion will help

Thanks
Javier

I'm not sure what is causing your issue but Ninjatrader definitely needs to get rid of that error message and replace it with something that has a real meaning.

I get that from time to time and last week I finally tested my memory. The results? You guessed it... Nothing wrong with my memory. Not a single error.

And like you, I too come back to my computer to find it has crashed. This messes up my indicators that measure volume areas on an hourly basis. (They get corrected next hour so not that big a deal)



That happens all the time. I guess I've just accepted the notion that Ninjatrader is a POS and I stay because I'm too lazy to learn how Sierra Charts or something else works.

Javier: This might not be too helpful, but I find that when nothing seems to work it's time to look elsewhere. Is your computer OK? From the description this might not be an NT problem.

I am a lifetime member of NT for 15 years and got fed up with crashes. Moved to Sierra Chart

Assuming you do not want to buy a new computer, maybe think of using a VPS service.

OR, I occasionally reset my windows PC back to its original, from store, set up. Iarchive my personal files to another scandisk memory stick. Then:

Reset or reinstall Windows 10
There are three options that allow you to reset your PC. If you’ve tried just about everything else and your PC still isn't running well, resetting it might fix the problem.
Option 1
1
Open Recovery settings or select Start Windows logo Start button > Settings Gear-shaped Settings icon > Update & Security Circular arrows Sync icon > Recovery.
2
Under Reset this PC, select Get started.

You will have to reinstall any applications. But NT8 will likely work fine after this. Let us know if you try this and it works.

Oh, BTW, the first thing I do after getting back to be able to open my browser is reject third party cookies. It helps a lot to avoid them.

I am a lifetime member of NT for 15 years and got fed up with crashes. Moved to Sierra Chart

Well, I gave up as well. I also have a lifetime license and invested in third party indicators. I can't blame anybody but me. I kept hoping the many issues would eventually resolve. But it was only wishful thinking. I switched to Sierra and took the loss.

This may be of use, so I will add this for general information regarding crashes. The performance part only refers to v8.0.nn, not v 8.1.

A couple of years ago I found that NT8 was taking minutes to load and would often crash. Even when loaded and running, it would crash later. The error message was the same as posted earlier. I had around 10/12 workspaces with some quite CPU intensive indicators on the charts (3 screens, 6 charts, DOM, databox, market analyser, and CC showing on each workspace). I spoke to a friend who had been using NT since v6. I have had it since v7. He has a lot of IT experience as well as NT experience. His comment was that it was almost certainly a combination of the amount of work I was expecting the computer to perform and the power of the computer. This was on an i7 3770, W10, 16Gb RAM which benchmarked at 6,400. I upgraded the computer and dedicated it to trading plus a couple of other processes, but no email or general browsing. The indicators have been increased but the number of workspaces is now down to about 8.
The new machine has 64Gb RAM, W10, runs NT8 and the OS from a SSD and benchmarks at 39,000. Since I have had this machine I haven't had a single crash.

As an aside, I have read a number of posts (maybe elsewhere), about bad fills through NinjaBrokerage and incorrect data. As far as v8.0.nn goes, I have had no problems other than the charts needing an occasional historical refresh. No bad fills. Regarding slippage in general, I don't leave stops in obvious places but even allowing for that, slippage hasn't been a problem.
