Artyom Trishkin:

You don't receive. You're writing it down.

Can I help you with something?

[Алексей Тарабанов]

Artyom, in a difficult life situation, help may not be out of place.

There are lines in the MT5 Helpdesk https://www.metatrader5.com/ru/terminal/help/trading/market_watch

• Purchase Orders - the total number of purchase orders;
• Volume of buy orders - total volume of buy orders

What is the difference? "Volume" is not synonymous with "Quantity"?

You have 3 banknotes (total number of orders) of 10 rubles each (total 30 (total volume of orders))....

You have 3 banknotes (total number of applications) of 10 roubles (total of 30 (total number of applications))....

It would be more logical to write "number of lots"

Not exactly. Each bid can contain a different number of lots.

You have 3 notes (total number of bids) of 5, 10 and 50 roubles (lots)(total 65 (total number of bids))....

I want to write a dll library and connect it to the main program (to mql4). In this dll library will be allocated dynamic memory to work with arrays that will be located within the library and not in the main program, if the main program is closed is it necessary to delete memory that was allocated within the library because the main program itself can not free memory occupied by the library or can it?
