optimization Symbol Properties changes?

 

I've done some optimizations lately that have different results for same EA/params/data/etc. As I understand, as long as you are connected to a certain broker, Tester takes the properties shown in "Symbol Properties" live from that broker.


My question is this: how do I know the exact properties when I pressed "Start"? I mean even if I look at properties and then close it and press "Srart", between the time I closed it and the time I pressed "Start" it might have changed.


Also - are the properties ever changed DURING an optimization run? Is there any better way/solution to control the properties while doing optimizations?
