I do strategy optimizations using ninjamobiletrader too, using the 16gb ram VPS because backtesting / optimizations use all the RAM available, so the additional RAM really helped speed up the calculations. They also offered me a dedicated 32gb RAM, 16x cpu machine for 199, but I think for my purposes it's overkill and the 16gb ram VPS works well.

Why is this post now in "NinjaTrader Mobile / General Questions" ? It was originally in "NinjaTrader Desktop / Platform Technical Support / IP list for NT8 connection through VPN request", which is where is still should be. In particular, this is NOT a question about mobile computing. It is a question about VPS offerings. Please put this back to where it belongs.


Well, I use 16 cores and 32 GB of RAM on Google Cloud, so 16 GB is insufficient for my work. Also, I get charged only when I use it, rather than a monthly fee. In particular, I'm certainly not paying $200 every month for compute services.

I think it's because I have it reserved for me 24/7 because I also use it for leaving strategies running when not backtesting. I also tried AWS before, and it would frequently change the NinjaTrader machine ID when not in use, making me lose access to my paid indicators.

Do you know if your NinjaTrader machine ID changes occasionally on Google when you're not using it to avoid the charges?

I've looked at Google Cloud pricing, and last time I checked Google compute + storage + networking + all the other charges were much more expensive when using it for the entire month. But if you only need it for a few hours a month and don't care about the machine ID changing, I can see how Google would make more sense to you.

I don't use any paid indicators. I've developed my own. Perhaps, as such, I've never had an issue with the machine ID changing. Perhaps the machine ID changes on GC, or maybe it doesn't; I really don't know.

If you want to use GC on a continuous basis, they do provide a discount. I've never looked at it in detail (and, no, I'm not getting compensated in any way by GC or any other cloud provider. My motivation here is to allow me access to any provider, and this seems be threatened by NT's 8.1 effort.)

I ran a GC quote for comparison, and the lowest I could get it down to was $475/mo just for the compute, for 16x cpu and 32gb RAM. That's with 1 year commitment, and doesn't include the networking fees + SSD storage. Although half of it is from the Windows Server licensing, but still, that's already included in the dedicated server from ninjamobiletradervps. I just really like how the 199/mo is the final all in price.

Unless I'm missing something, way cheaper with my current ninjamobiletradervps, and they even help me with my Ninjascript errors as well. I doubt GC even has on demand phone support at this price

Well, I pay less than a dollar a day for my GC trading machine, so that's $20/month, all in.

Our traders backtest on both our virtual and dedicated servers. What interval are you testing? Tick? Minute?

[spottysallrite]

I use tick on the futures ES, then calc my self-designed and developed indicators from that. I've got 10 years of tick data, which I use for backtesting/ optimization, which typically take several days to run (cycle time for each iteration is ~20 minutes).

If you are testing 10 years of tick data, you are going to want to go with a dedicated machine.

I assume you are running these locally? How do you use your PC while the tests are running?

Running backtests on our servers would ultimately save you time (and headache by ensuring your machine is running and connected throughout the duration of the test).

We can give you a demo, reach out via live chat at [redacted] or email us [email protected].

I've had hit or miss experiences with market replay for years now.
For example I will leave a strategy enabled that takes a few trades and by end of day it's done and it will have made like $300 for example.
Then immediately after the market closes, I will download the replay data for the same day and go back and replay with the same strategy and it's like a negative $200 loss.
Wildly different results.

I have also found that i have 2 different VPS for example, and on the same data feed, same chart, same instrument, I will have same strategy running on both VPS they sometimes do not have the same entries. Like one will enter but the other didn't, and then sometimes it's the same.

It's crazy.
