The article deals with managing MetaTrader user interface elements via an auxiliary DLL library using the example of changing push notification delivery settings. The library source code and the sample script are attached to the article.
It has been over a year since MQL5 started providing native support for OpenCL. However not many users have seen the true value of using parallel computing in their Expert Advisors, indicators or scripts. This article serves to help you install and set up OpenCL on your computer so that you can try to use this technology in the MetaTrader 5 trading terminal.
This article focuses on some optimization capabilities that open up when at least some consideration is given to the underlying hardware on which the OpenCL kernel is executed. The figures obtained are far from being ceiling values but even they suggest that having the existing resources available here and now (OpenCL API as implemented by the developers of the terminal does not allow to control some parameters important for optimization - particularly, the work group size), the performance gain over the host program execution is very substantial.
In late January 2012, the software development company that stands behind the development of MetaTrader 5 announced native support for OpenCL in MQL5. Using an illustrative example, the article sets forth the programming basics in OpenCL in the MQL5 environment and provides a few examples of the naive optimization of the program for the increase of operating speed.
Multitimeframe navigation and research tool MT4 ( XY expert advisor) is a convenient tool that allows analyzing the trading instruments on different time frames and fast switching between them. Easy to use. It has no adjustable parameters. Charts with an XY Expert Advisor can be either the same symbol (instrument) or different (from version 2.0). When a symbol is changed on one of the charts with the XY expert advisor , cascade change of symbols occurs on other charts with the XY attached. The
The Market Profile was developed by trully brilliant thinker Peter Steidlmayer. He suggested to use the alternative representation of information about "horizontal" and "vertical" market movements that leads to completely different set of models. He assumed that there is an underlying pulse of the market or a fundamental pattern called the cycle of equilibrium and disequilibrium. In this article I will consider Price Histogram — a simplified model of Market Profile, and will describe its implementation in MQL5.
