The word "handle" in programming has a long history and comes from the early operating systems.
🕰 How the term appeared
- 1960s–70s: In the first OS (for example, Multics, early UNIX‑like systems) there was a need to work with many resources — files, processes, devices. Instead of programmers directly operating with physical memory addresses or devices, the system issued a descriptor — a special identifier.
- Windows API (1980s–90s): Microsoft popularized the word *HANDLE*. In WinAPI any resource (window, file, font, device context) was represented by a numeric value — a “handle.” This was an opaque pointer: the programmer doesn’t know what’s inside, but can pass it to functions.
- Analogy: a handle is like a cloakroom ticket. The ticket itself is not the item, but it lets you access the needed object.
📘 Usage in different environments
- C / C++ / WinAPI: HANDLE is a base type for any resources.
- Java / .NET: although the word “handle” is not always used explicitly, the concept exists as a “reference” or “descriptor.”
- MQL5: when creating an indicator (iMA, iRSI, iCustom) the function returns an indicator handle — an integer used to access buffers via CopyBuffer().
🔑 Why not “pointer”?
- A pointer directly refers to a memory address.
- A handle is an abstraction: it may be an index in an internal table, a pseudo‑address, or even a complex structure. This makes the API safer and more portable.
---
👉 So, the word “handle” in programming is a legacy from WinAPI and system programming, which has become a universal term for a “resource identifier.”

Changing the history of arrows.
This is a script — more of a joke than a fully-fledged piece of code.
However, it does its job once: it removes the system arrows from the trade history and makes significant changes

Shows good results on gold (needs some optimization). For forex currencies, you can find options for rebate services.
