How the MT5 system is handled in series, and how does it work? - General

pivomoe:

29gb disk. The tests are from home machines and I understand you are either from a VPS or a virtual machine.

This is how the SSDs are partitioned. The last one (Z:) is the RAM disk for the MT5 tester.

My Sleep(1) test

Windows 10 build 17134, Intel Core i7-2600  @ 3.40 GHz, 7 / 15 Gb memory, 97 / 195 Gb disk, IE 11, UAC, GMT+3

TestSleep (PLD-12.20,M1)        total 19979585 microseconds (1.998 ms per iteration)

p.s I seem to have an even weaker computer than yours.

Yours:

What is your operating system? Probably some LTSC version for ATMs ?

Slava:

Not always and not everywhere a tenth of a millisecond. Checked with a simple script

Here is my log

OnTick users always see the freshest tick.

OnBookEvent users always see the freshest tick.

But if you want to compare ticks received with OnTick and received with OnBookEvent you're in for a disappointment because the events are processed sequentially and not in parallel. What user pivomoe tried to tell you

The handlers are handled in series? This is fundamentally wrong!
All the handlers should run in parallel!
And where's that statement about everything being asynchronous in mt5?

Please comment on this!

SymbolInfoTick() is executed in blocking mode or non-blocking?

For example, it is located in the body of while loop and there is no connection or market is closed for weekend,
it will be blocked by stopping the loop or it will be executed asynchronously?

Asynchronous and multi-threaded programming Close all order at graceful shutdown of services
