One of the important aspects in financial trading is the ability to monitor performance and analyze your trading history. Past data allow you to track the trading dynamics and evaluate the overall performance of the strategy used. This is useful for all traders: for those, who perform operations manually and for algorithmic traders. In this article, I suggest creating tools that implement such a function.

This article will be divided into 2 sections. In the first (technical) section, I will describe methods for generating trading reports based on the bulk of information, which is stored in your terminals. This section deals with the source data used for analysis. In the second section, we will deal with the main values, by which we will evaluate the trading retrospective on the selected data. Data sampling can be varied: all assets or a selected symbol, for the entire available history or for a certain period of time. The analysis results will be presented in a separate file and briefly visualized in the terminal.

When developing trading algorithms, we almost always encounter a problem: how to determine where a trend/flat begins and ends? It is difficult to find a clear-cut solution. This goal seems achievable by combining the both trend-based and flat-based strategies in one algorithm. In this article, we will create a universal indicator that will combine signals for different types of strategies. We will try to simplify the generation of trade signals in an expert as much as possible. An example of combining several indicators in one will be given. This will be done using object-oriented programming, with each indicator or its part being implemented in the form of a class included in the main program file.

There are numerous trading strategies out there. Some of them look for a trend, while others define ranges of price fluctuations to trade within them. The market is volatile. Trends are always followed by flats. This provides profit opportunities both for trend followers and those who trade within ranges. When one of these two groups makes profit, another either loses or waits for the right moment.
Is it possible to combine these two approaches to increase profitability? Can two strategies complement each other? Let's try to combine seemingly different trading models and see the result of such a combination.

Elder-Ray trading system was described by Alexander Elder in his book "Trading for a Living". It is based on Bulls Power and Bears Power oscillators, as well as Moving Average trend-following indicator (EMA — exponential averaging).


The system is both simple and complex:

• it is simple if we perceive it literally: buy if a trend is upwards (EMA) and Bears Power is below zero, but is increasing;
• it is complex, if we read more carefully and also look at the chart EMA and Bears Power are launched at: it turns out, it is not as simple as it seems since such conditions are few.

In this article, we will go through all the stages from simple to complex and check two types of trading system:

1. all indicators on the same chart (and therefore, on a single timeframe);
2. in combination with the "Triple choice" system.

It is unrealistic to launch this type of process each week manually, so we looked for an existing mechanism to perform repetitive tasks but without success (for MetaTrader 5) so we developed this one.

The implementation of this process requires a minimum knowledge of MetaTrader 5, its optimization mechanisms and programming.
Thanks to Igor Malcev who write the article "Automated Optimization of a Trading Robot in Real Trading" for MetaTrader 4.
