Does spread check works on MT5 strategy tester?

[Syed Oarasul Islam]

Hello,

I am moving from mql4 to mql5. I was wondering does pragmatically spread check works on mt5 strategy tester? 

What will happen if I use a spread check?

And how the experienced traders cum programmers see the spread check phenomenon? Is it worth it?  If it is what should be the usual spread check value on FX majors?

Thanks for your time
