The article provides a detailed description of the process of testing and optimizing Expert Advisors in the MetaTrader 4 Strategy Tester.

The article introduces a structure for an Expert Advisor that trades multiple symbols and uses several trading systems simultaneously. If you already identified the optimal input parameters for all your EAs and got good backtesting results for each of them separately, ask yourself what results you would get if testing all EAs simultaneously, with all your strategies put together.

In this article, we will consider the development of a multi-symbol volatility indicator. The development of multi-symbol indicators may present some difficulties for novice MQL5 developers which this article helps to clarify. The major issues arising in the course of development of a multi-symbol indicator have to do with the synchronization of other symbols' data with respect to the current symbol, the lack of some indicator data and the identification of the beginning of 'true' bars of a given time frame. All of these issues will be closely considered in the article.

Securing MQL5 code: Password Protection, Key Generators, Time-limits, Remote Licenses and Advanced EA License Key Encryption Techniques

Most developers need to have their code secured. This article will present a few different ways to protect MQL5 software. All examples in the article will refer to Expert Advisors but the same rules can be applied to Scripts and Indicators. The article starts with simple password protection and follows with key generators, licensing a given brokers account and time-limit protection. Then it introduces a remote license server concept. My last article on MQL5-RPC framework described Remote Procedure Calls from MetaTrader 5 to any XML-RPC server.

I will make use of this solution to provide an example of a remote license. I will also describe how to enhance this solution with base64 encoding and provide advice for PGP support to make ultra-secure protection for MQL5 Expert Advisors and Indicators. I am aware that MetaQuotes Software Corp. is providing some options for licensing the code directly from the MQL5.com Market section. This is really good for all developers and will not invalidate ideas presented in this article. Both solutions used together can only make the protection stronger and more secure against software theft.

The article describes one of the approaches to determining a useful signal (trend) in stream data. Small filtering (smoothing) tests applied to market quotes demonstrate the potential for creating non-lagging digital filters (indicators) that are not redrawn on the last bars.

Updated MQL4 has the new format for storing historical data and provides the appropriate MqlRates structure for convenient storage of Time, Open, Low, High, Close and Volume values. For many years, traders have developed their MQL4 applications that collect and store their data in HST files for generating offline charts. We can assure you that all previously compiled EX4 files will work in the new MetaTrader 4 terminal the same way as before.
