My main concern is reliability. The idea is to run many automated strategies on many instruments, so eventually any down time can be a big headache. Many VPS guarantee 99.999% up time, and I suspect it is more reliable than running everything from my own PC. There is also licencing issue: if I want to run one MC at home for testing and another on the cloud I need two licenses. On the other hand MC allows running multiple instances on one machine, virtual or physical. So I can set up everything on VPS and run all trading and testing via remote desktop application.

This is almost exactly what I have set up and I can tell you it was WORTH IT. I have about 75 different symbols (equities and futures) all algo trading. I use Tradestation for my live trading and run multicharts on the same vps for backtesting at the same time using Tradestation data. I do not backtest using all cores though as the latency is greatly reduced for my live trading. The great thing about multicharts is you can quickly select core usage while backtesting. I set backtesting to use 4 cores if I am away and 5 if I am monitoring. I only use all 8 cores during downtime which is weekends or 1 hour futures break. I will DM you my server details tomorrow. In algo trading, 1 missed trade per month could completely ruin your trading results. You have to take ALL valid signals. It's a statistics game and you can't predict winners and losers.

I am currently looking and asking questions at mytradehost.com. They are somewhat more expensive, but have more options than speedy in their VPS packages.

After researching the options for a few hours I realize that while cheaper services are... well, cheaper they will turn out more expensive. In terms of crashes, missed trades and missed stops. SO I am very careful here.

Options like what? Having a VPS hosted in Shenzhen or Moscow (or Miami, Dallas, SF, ...) where there's no market gateways or market data servers?
This is typically the kind of company which is reselling generic providers VPS, and not owning/managing their own infrastructure, who added some "trading flavor" on their web site.
I checked their web site and I'm surprised that some of the brokers mentioned in "Special Offers for Select Clients" are long time clients with us at Speedy...

About AWS and others generic cloud providers there's few problems:
- you never know what would be your costs at the end of the month (you're not only paying for the RAM/CPU usage but also for the disks I/O, the network usage, ...)
- it's not as easy to use as a ready to go VPS
- there latency to the market gateways is not great
- good luck to talk with the support!

@Cutloss: the CME VPN tunnel is not retail users (and $500/mo for a VPN access, seriously...).

About uptime/reliability we good numbers (but I won't recommend to not install updates and not restart Windows in more than 4 years!) :

When you algo trade, do you use a 1:1 risk to reward ratio?

It depends on the asset and how you trade it. If you are statistically 90% accurate on your trade you can take a higher risk. Many algo's have defined profit and loss, some use trailing stops, some don't utilize profit or stop losses and they can all be profitable. For my algo's I look for a high reward/risk ratio so I am typically above 1.2 avg win/loss and above 50% win/loss rate, typically above 55%. I target above a 1.3 PF but average around a 1.7 PF for portfolio's with some markets returning 2.5+ PF's. The key thing for me though is consistency of returns. You can have a 5 PF but if it all came from 2 months of trading over a 20 year period, its difficult to say if you can expect those kinds of returns. There is probably way better information on this somewhere else on the forum as well.
