Has anyone successfully upgraded to AmiBroker 6.39.1 RC?

I tried today a few times without success and had to unistall everything and go back to 6.30.5.

Just curious if the new features are noticeable and worth the effort to get it working. Although I have no idea what is needed to get it to work on my pc.

Yes, I have just installed the upgrade and have no issues at all so far.

One thing that I have noticed in all versions is that after I open Amibroker I need to run a quick backtest before running my exploration then I get the selections. If I change to another analysis then I do the same process. Its a little strange but its just a extra 10sec fix.

I just purchased a new laptop and installed Amibroker 6.40.5, clean install with no files copied from my old computer running 6.30.5.

Running the same .afl file, same exclude list and same market I am getting slightly different backtest results when comparing the result produced by each computer. I have reviewed all of the amibroker settings and exclude lists and so now the difference appears to just be rounding differences.

Does anyone have a process or checklist they use for setting up a clean instance of Amibroker for trading an MOC system on the US market?

Did you find there to be slight differences in the results produced by the two computers after all the settings were confirmed the same?

What’s the main differences?

Is it stock selection….. ? Different entry prices, # of shares purchased? Or end Profit/Loss?

If end profit/loss, maybe check commissions are the same between each computer?

I’ve inadvertently forgotten to include them in the past when shifting Amibroker to a new computer.

I’ve also observed that the Norgate database can ‘corrupt’ if I’ve used it for ‘several years’ before doing a fresh install of everything (Norgate/Amibroker)…. it’ll still work, but the results were a little ‘off’ between old/new laptop.

Glen, Thanks for reply and prompting me to dig deeper. After comparing the exploration files, old computer to new computer, I found the new computer exploration results includes a few stocks not included in the old computer results. Maybe it is a database issue, so I will go down that route and do a fresh install on the old computer.
