MQL4 Reference MQL5 features MQL5 functions Working with OpenCL

Working with OpenCL

OpenCL programs are used for performing computations on video cards that support OpenCL 1.1 or higher. Modern video cards contain hundreds of small specialized processors that can simultaneously perform simple mathematical operations with incoming data streams. The OpenCL language organizes parallel computing and provides greater speed for a certain class of tasks.

It is recommended to write the source code for OpenCL in separate CL files, which can later be included in the MQL5 program using the resource variables.
