For those who have limited internet or processing power

  Hello.

  For those who has limitations on reliable broadband internet access or computers that can’t run 24/7.

  After some testing on various computers and internet throughput, I came to realise the common denominator that limits the speed of backtesting and WFA is internet bandwidth.
  Ok – one never have enough processing power and RAM.

  Talk to your local ISP or an ISP anywhere in the world.
  Let the ISP setup a computer for you that has direct access to the backbone or at least very fast internet. The ISP can setup a VM (virtual machine) with a secure VPN connection to this machine. You won’t need much storage space on the computer so that’s not an issue for the ISP.  Can be any operating system. Whichever OS you are familiar with.

  The idea is then you can login remotely to that server using remote desktop software and run your time consuming backtesting/WFA on that machine. You stop/start multiple backtesting/WFA processes on this machine and then log off. After so many hours you login change some parameters and let it run again.
  You can access with remote desktop and VPN from anywhere in the world.

  The results you can copy&paste from remote computer to your local computer for further analysing, tweaking/tuning.

  Yes, this will cost some money but not as expensive as you think. Compare costs to speed and realibility with the frustrations on the side.

  How much faster will it become? Seems to be really some effort.

  Then we still all hope for the MUCH faster backtest engine Nicolas announced.

  I have not noted the differences in time it takes.
  I compared running on my laptop at home with LTE internet connection VS when I’m connected to a network point that has 4 x 10Gig fibre. Same laptop.
  There is a big difference though.
  I will make some comparative tests and publish it here.

  Having access to a powerful machine with fast internet access that is running 24/7 is also about convenience.
  I’m away from home many times for weeks at a time and during this time I don’t have fast internet.  Having a remote machine with fast internet solves that for me.

  Yes am also waiting on the latest PRT release in anticipation 🙂

  I have suggested to ProRealTime that it might be a good product development to offer an “in house” vpn service for backtesting/WFA purpose. If the vpn would be inside the PRT network,  there would be no issue with broadband, and the combination limitation of 100k could most likely be millions in stead 🙂 I keep my fingers crossed!

  Why PRT make everything is his servers?

  and why always my backtesting stops between 5am and 6am! I hate that!

  The new backtest engine is already deployed for prorealtime.com account. Backtesting is on average, now up to 5 times faster, depending of the code.
