I have problem to open 40 MT4 on my PC. Maximum open 32 MT4 platforms.
This problem happen whit this new built 600 and whit 604 is a little better.
Before, whit version 509 I opened over 40 MT4 platforms.
How can I fix this?
You can't . . . contact the MetaQuotes Service Desk
And if you continue to double post you will receive a BAN, please do not do it.
ArrayCopyRates() as in passing price data to a DLL and then processing it using the MqlRate structure? Not ArrayCopy()?
If ArrayCopyRates(), then I think you need to replace the DLL: https://forum.mql4.com/60417#899562. I haven't re-tested this with v604, but AFAIK MetaQuotes simply are not maintaining backward compatibility in this area. The DLL has to be changed to use the new structure.
gchrmt4 Thanks. you may be right but below is a quote from The documentation about the new release . It Clearly states it has been left intact. I think the way the oldl system worked was arraycopyrates took ALL the data at run time and set aside memory for it. This one I am not sure what is doing.
