Cosine distance and cosine similarity
Info
The Cosine distance and cosine similarity is a Library for MetaTrader 5 that function to calculate the cosine distance and the cosine similarity. The cosine distance between 2 vectors A and B is :So 1-CosineSimilarityAnd the cosine similarity is :In simple terms :the cosine of the angle between the 2 vectors or , the dot product of the vectors divided by their magnitudes multiplied Here is the simplest explanation (although his cos(45) is wrong) :.
Usage
This tool is typically used for enhancing chart analysis and decision making.
Platform
This Library works exclusively on MetaTrader 5 (both build 600+ and newer versions).
Setup
Place the downloaded file in MQL5/Libraries folder via File ? Open Data Folder in MetaTrader 5.
How to Install and Use Cosine distance and cosine similarity
1. Storage: Place library files in the MQL/Libraries directory to ensure they are accessible to your projects.
2. Implementation: Include the library in your code using the #import directive, ensuring you match the exact function names and parameters.
3. Compilation: Ensure the library is present in the directory before you compile your main EA or script, as the compiler links them during this phase.
4. Management: Keep libraries organized in sub-folders if you manage many custom functions to maintain a clean project structure.
Frequently Asked Questions
Q: What is a library file used for? A: Libraries store reusable code modules, allowing you to centralize common logic used by multiple EAs or indicators.
