No.31: Indicators - One indicator line used
Description
You can find an example for the Expert Advisor Builder on this page. If you need to familiarize yourself with the MetaTrader strategy tester and the Expert Advisor Builder, please begin with the Getting Started article.
This example illustrates the process of generating signals using indicators. Indicators are widely used tools that simplify a price chart, making the information more digestible for human interpretation or automated processing. These indicators can either be used in conjunction with each other or interpreted independently. A Simple Moving Average indicator (SMA) is in use in this example. A signal is generated whenever a turning point, indicated by the angle (displayed in the chart window at the bottom), is detected. This leads to placing a long order with an enabled average true range stop loss trailing and a risk ratio-based (1.4) take profit. As with many examples for the Expert Advisor Builder, only one trade can be open at a time. This implies that some signals may be overlooked.
Please note that this is not a plug-and-play trading strategy. A trading strategy needs suitable adjustments, fine-tuning to the timeframe and symbol, and thorough backward and forward testing. Therefore, providing fully working trading strategies as read-to-use examples is impossible. However, this example could serve as a foundation for your trading strategy.
Reset of inputs
Locate the Expert Advisor Builder application in the dropdown menu of the strategy tester settings under FEA Trading\MT4\Expert Advisor Builder 2.0 if you're using a MetaTrader 4 instance or FEA Trading\MT5\Expert Advisor Builder 2.0 if you're using a MetaTrader 5 instance. You can replicate the entire example in minutes by following the steps outlined in this article. To begin, kindly reset the strategy tester input as indicated.
The default input parameters of the Expert Advisor Builder are designed to be highly functional. This implies that only some parameters must be adjusted when creating a new strategy. As a result, even with minimal reconfiguration, the output strategy can be significantly different.
Inputs configuration
Most examples can be executed in any timeframe and on any symbol. However, please set EURUSD as the symbol to be tested, M15 as the timeframe, select Open prices only (MT4) or 1 minute OHLC (MT5) as the model, and the previous four weeks as the test period. Finally, enable the visual testing mode.
Refer to the table below to set up the input parameters for the Expert Advisor Builder.
| Input variable within MetaTrader (Identifier in SET file) | Example value | User manual chapters |
|---|---|---|
| > (OUF) Idea output description (max 63 characters) (IN_strOufIdeaOutputDescription) | No.31: Indicators - One indicator line used | Output Folder |
| > (INA1) CONF, Signal in use (IN_enmIna1SignalInUse) | ON | Configuration Available Indicators and Default Values Example |
| > (INA1) COND, Angle limit condition (IN_enmIna1AngleCondition) | CROSS LIMIT 1 |
Confirm the inputs by pressing OK, and finally, start the test run with Start.

The underlying algorithm is highly optimized for execution speed. Generally, it only takes a few minutes until the entire test period is simulated. At the end, you will see a chart similar to the following.
To reproduce the chart from this example, you can download and use the SET file package eab_example_31_v_2_0.set.
