// Наследование по умолчанию приватное. И в С++ и в mql

public наследование можно не указывать, оно по умолчанию

It's not good. If you started to copy C++, you should copy it exactly, and in this case you mislead respected programmers. After all, this is the only difference between a class and a structure - inheritance by default

This is bad, if you started to copy C++, you should copy exactly, but in this way you mislead respected programmers.

Apparently, it was left over from times immemorial when the decision to move to C++ had not yet become "party policy".

Now inheritance is private by default like C++.

Well, that's the only difference between a class and a structure - inheritance by default.

Well, it's not exactly so. I, for instance, can name three more differences at a glance

MetaDriver:

I agree.

A "command" to forcibly null all prev_calculated for the selected symbol would also be useful. With the subsequent generation of a tick would be a good combination.

Oh!

Write what the sd says?

Found such a command:

        MqlRates R[1];
        CopyRates(ChartSymbol(id),ChartPeriod(id),50000000,1,R);  // Обращение к бару 138-летней давности (на минутках)...:)

Exactly zeroizes all prev_calculated and causes generation of tick. Tweak: it does it twice in a row, which is unnecessary, but it works flawlessly. :)

MetaDriver, I've already patented this bug :)

Such a team is found:

Thanks. I'm managing with a timer for now, but I think it'll come in handy :)

Shh! Do not say it is a bug. They will fix it, but will not give you anything in return.

There's no one there, everyone's at the airport to meet some prick from Japan.

Using this bug leads to consequences like this...

[Maxim Khrolenko]

Please tell me (or give me a link) how to make it so that when optimising for a certain combination of input parameters, the test is not performed.

For example, there are parameters A and B, where start=10, step=5, end=30. At that, if B<=A, then test has no sense, e.g. at B=10 and A=15 we don't need test.

P.S.: found a solution.
