Yes, I understand, anyway the native one is better, you have to watch the sockets and the logic is more cumbersome.
For example, if you run several copies, it becomes a mess
but in other words, you may just copy Python code fragments directly into the Expert Advisor's code and that's it
but if I copy R, it's ok, but if I redo it, it makes no difference at all
Yeah, so is 4. Once I ported lwma and BB computations from 4 to dll for fun (I was playing with TDI) and got exactly the same ~10% performance gain. Both compilers are very decent.
Wine kernel is written in simple sys, without classes, by the way. The cheduler is written in asm. vtable has a noticeable effect on performance in system cases.
I want to bring you closer to reality given the discussions of the thread What would it take to get everyone to finally switch to MT5? (collecting opinions):
Progress is unstoppable
That's all great, but there are needs and ways to implement them. Who needs to quickly write an indicator or check the manual strategy - that's 4. Who needs to get high on ticks - that is 5.
Regarding the speed of the trading part for the user-trader - very ambiguous. The difference is not perceptible. However, 5 is aggressive to traffic. Observation: music is playing on laptop, at startup 5 music starts stuttering (network interruptions load, of course), after establishing connection and downloading missed data stuttering goes away. In 4 there is no such thing. So sorry, but 4 lighter than 5 will be both the CPU and the network.

If ticks are not busy, there is a load on the network and computer, but after that there shouldn't be any differences.

Here you go, it was on Wednesday, not Thursday, my mistake. File E:\Forex\School\MT5_Develope\Tester\logs\20190206.log. In the last run of17:11:24.609, pressed Stop manually as the loading bar froze at 2/3.
And then ran again tonight with the same date, all went fine.

Press start again and stop talking about how replacing one click is a thousand times more complicated.

Another set of self-deception.
The speed of MQL4 code is the same as in MQL5, while rewriting from MQL4 to DLL gives 10% speed increase.
Another set of self-delusions.
For you, the speed of MQL4 code is the same as in MQL5, rewriting from MQL4 to DLL gives 10% increase, for you "the speed of the trading part is ambiguous".
This is a "reality given to us by experience". And rewriting from 4 to dll is also a metric.
The speed is really ambiguous, because at (re)connect the system stutters, and after that 5 for forex is indistinguishable from 4 (although every newscaster tells us that "everything was rewritten from scratch", but charting hasn't been improved for 15-20 years).
This is 'reality given to us by feeling'. And rewriting from 4 to dll is also metering.

I've got the proof on my hands as a developer, and you've got the feel of a laptop with stuttering sound.
Upgrade your laptop and don't mislead people with tales of simplicity.
