Different hardware could create big difference result in portfolio trade ?

Postby strelow » 31 May 2020

Hello

I use two machines :

1 - I7 2th generation 16GB RAM
2 - i7 8th generationn 32 GB RAM

-Same files , same software installed , same base data feed.

For my surprise running same portfolio trade I huge differences performace like machine 1 give me 27,53 Cum. Profit (%) and other -23,76% Cum. Profit (%) .

I cant understand why this happen . I already checked everything

Other test I did Running same machine but Mc12 and MC14 beta here have big difference again too but here I know is a different sofware can cause this but first example only i have hadware difference that I have more 16GB of RAM in machine 2 .

There is any other thing in my setup that I need to ckeck to understand why this have even I using same files ?

Hello strelow,

Please make sure that you use the same set of signals, the same portfolio workspace, the same symbols, etc.
According to your reports (Portfolio_Machine_1 and Portfolio_Machine_2 ), there is a difference in the list of trades, symbol names, prices, and position entry time.

Please refer to the attached screenshot with the differences highlighted.

Hello Vlada

I have sure that I am using same setup . My doubt is that why this list that you show is different .If you look tab setting you will see the same set up for both machines.
You analysed the output data . Try to see the input data in reports.You will see that I used same 204 instruments to simulate
The decision of multichart buy different paper in different period is why I asked you.
There any test that I can do to prove you I am using the same setup ? I already put all my setup attachement in this message.
My procudure was:
using same cloud folder I opened portfolio trade both machines that are using same data server I runned the same portfolio workspace file and runned backtest simulation . I only was waiting that machine more faster will finish the process first .
