Is 'Allow DLL import' and 'Allow modification of signal setting ' in MQL4 Indicators dangerous?

Rules of Using the Virtual Hosting Service MetaTrader (Forex VPS)
No DLLs are allowed on a Virtual terminal. There is no physical capacity to use DLLs there.
If a program launched on a Virtual terminal tries to call a function from any DLL, this EX4/EX5 program is immediately stopped due to a critical error. Any DLL calls are forbidden.
Some other limitation - from VPS rules -
Execution of any unrelated trades on the account managed in a Virtual terminal can lead to unpredictable trading results.
Some more limitation (from this article) -
Terminal global variables are not migrated to the virtual hosting. If you need to initialize lots of variables when starting a program, you can use reading from files that can be passed using the "#property tester_file" directive.
It is what I found now.
"disabled dll" is nothing ...if Ea is calling dll (irrespective off - you disabled it in Metatrader or not) - this EA will not work in VPS.But you only know from the code of EA - your EA is calling (trying to use) dll or not ...
As to code 0 ...You can try to see/read VPS logs to understand about (something).I am not a coder (and I am not VPS expert) to provide the correct reply concerning "code 0" error; and the service desk is not providing the personal support for now sorry.

VPS is the copy of your Metatrader in the cloud.To make this copy of your Metatrader in cloud so you need to open chart (or charts) and attach your EA to the chart (or to the charts) to ready to trade.After that - you make the migration: you are synchronizing your Metatrader with open charts with EA attached to the charts - with the copy of your Metatrader in the cloud.Once you synchronized (once you sent everything to VPS) so you can close your pc (in you want): your EA will work on VPS (means: your EA will work on the copy of your Metatrader in cloud).
And all those actions (with possibe errors) are written in your VPS log files (you can check it inside your home Metatrader).
