More is possible for 32. Only the motherboard limits this. It seems that up to 200 GB can be connected. I saw a table somewhere.
Vadim, is this the kind of unlock you mean?
TarasBY:
You can Google "Windows Task Scheduler". You can check it out here.
Do you need to create separate programs (tasks) to disable enabled terminals?

Docent, read the document at TarasBY 's link carefully and don't make up nonsense.

int GetCrossingMa(double& i_maFast1, double& i_maFast2, double& i_maSlow1, double& i_maSlow2) function gets the crossing signal.

intGetStochSignal(double& stochD1, double& stochD2, double& stochK1, double& stochK2) function receives signal from stochastic.

The void GetMomentumSignal() function gets the value of momentum.

The int GetSignal() will get the general signal based on the previous 3 functions and not only them. The question is this. Since theint GetSignal() function is the main one, so to speak, and it gets the main signal, I get all the values of the flaps(i_maFast1,i_maFast2, i_maSlow1 andi_maSlow2) and stochastics(stochD1,stochD2,stochK1,stochK2)

Was I correct in optimizing the code?

Of course, all parameters obtained in the functionGetSignal() are passed by reference to the corresponding functions.

But here this fragment 

     if( GetCrossingMa(double& i_maFast1, double& i_maFast2, double& i_maSlow1, double& i_maSlow2)==CROSSINGTOUP || i_maFast1>i_maSlow1 )

I don't like poking around in left-hand code, but it immediately struck my eye why there is an & (!) after double in functions. This is what causes errors!

I don't like digging in custom code, but I immediately noticed why there is & (!) after double in functions. This is what causes errors!

So it makes sense. It means transferring parameters via links.

To avoid explaining the code in details, I will explain it briefly.

There are 3 functions:(int GetCrossingMa, int GetStochSignal and int GetSignal())

The int GetSignal() function gets values of flaps and other indicators which are passed by referenceto non-core functions(int GetCrossingMa andint GetStochSignal) to get corresponding signals in them. I want to do it to avoid getting the same data in different functions. I don't think it's wise to calculate the same mask in 2 or more functions. It's easier to just calculate it once, and that's it. Why waste additional resources on this?

And in the last function GetSignal() you make "adding" of all signals (by yourself).

P.S. There is a "delicate" moment in getting the signal from the indicator. For example, you can fix the fact of finding maSlow over / under maFast, or you can "catch" the moment of their intersection. The approach and the code are different.

A little bit in Perl and a little bit in Pxp. But I haven't seriously approached other languages as I haven't needed to. Does it matter?
