Virtually any trading strategy can be formalized and implemented in the form of an Expert Advisor, which can automatically trade for you. A trading robot never gets tired or suffers from stress; it accurately follows its algorithm and is much more responsive to market changes.
The trading platform provides all the necessary tools for Expert Advisor development: the powerful MQL5 language with an integrated development environment, a multicurrency tester for testing and optimizing strategies, and the Code Base of free trading robots
from MetaTrader 5 Help → Algorithmic Trading, Trading Robots → Strategy Testing
The Strategy Tester allows backtesting strategies that trade multiple symbols. Such trading robots are conventionally called multicurrency Expert Advisors.
The tester automatically downloads the history of required symbols from the trading platform (not from the trade server!) during the first call of the symbol data. Only the missing price history data are additionally downloaded from the trading server.

How to visualize multicurrency trading history based on HTML and CSV reports
Since its introduction, MetaTrader 5 provides multicurrency testing options. This possibility is often used by traders. However the function is not universal. In particular, after running a test, the user can open a chart with performed trading operations. But this is only a chart of one traded symbol selected in the strategy tester settings. The entire trading history of all used symbols cannot be viewed after testing, while visual examination is not always efficient. Additional analysis may be required after some time after testing. Also, a report can be provided by another person. Therefore, a tool for visualizing trading on multiple working symbols based on the HTML testing report would be very useful.
The previous article provided a description of the HTML parser based on CSS selectors. The parser extracts the list of deals from the HTML report, based on which we can trades can be formed (graphical objects). Parsing of CSV files from the Signals section is a bit easier, while the file format for the MetaTrader 4 (*.history.csv) and MetaTrader 5 (*.positions.csv) signals is supported by the built-in MQL functions.
