Sleep and RefreshRates

I've noticed some codes Sleep at the start of a code then Refreshes to update values before continuing with the rest. Is it not better to Sleep at the end of the code? Then RefreshRates is not required? edit: should probably specify purpose: to make sure the code only runs once per second for

How many MT4 terminals could this laptop run?

Asus Transformer Book T100 . Intel Atom Z3740 1.33GHz Quad Processor, 32GB SSD, 2GB DDR3, Intel HD Graphics, Win 8.1 I didn't find much in the way of minimum specifications for MT4 but I want to run this laptop 24/7, do you think I could run 12 MT4 EA terminals?

MT4 updates and 24/7 EAs (and other questions)

If there is an update to MT4 and I am a running an EA 24/7, what happens? Does it just keep going as normal? Or does it auto-update then restart itself? Can you run two different EAs on two different chart windows on the same account (same terminal)? How many instances of MT4 can I have running at

Was return(0) important?

Just a curiosity question more than anything, since I deleted most of the return(0)s in the old build with no ill effects. The new 600 build debugger keeps telling me off if I accidentally copy and paste return(0); into the void OnTick section. My solution was to delete return(0)

Using switch to determine the AccountCurrency() ?

I tried the following but it didn't work. The error in compiling says it expected each case to be an integer but I have strings such as "USD", "EUR", etc. double USDBalance; switch ( AccountCurrency ()) { case "USD" : USDBalance = AccountBalance (); break; case "GBP" : USDBalance =
