MQL5 Wizard - Trading Signals Based on Three Moving Averages - MetaTrader 5 Expert - MT4/MT5 Resources
MQL5 Wizard allows automatic creation of Expert Advisor codes. See Creating a Ready-made Expert Advisor in MQL5 Wizard for details.
Here we will consider a trend strategy based on three moving averages. This strategy is called "Signal Based on Three EMAs" . To determine the trend, it uses three exponentially smoothed moving averages: FastEMA, MediumEMA and SlowEMA.
The strategy is implemented in the CSignal3EMA class (signal3ema.mqh must be placed in terminal_data_folder\MQL5\Include\Expert\Signal\Signal3EMA.mqh).
Figure 1. Trading signals based on three moving averages
The trading strategy is implemented in the CSignal3EMA class, which has some protected methods to simplify access to the values of the three moving averages (fast, medium and slow):
Double fast EMA ( Integer Industrial) // Returns the fast EMA value of the bar Double the middle EMA ( Integer Industrial) // Returns the middle EMA value of the bar Double Slow EMA ( Integer Industrial) // Returns the slow EMA value of the bar
1. Open a long position
An uptrend is determined by the following conditions: FastEMA>MediumEMA>SlowEMA:
//+------------------------------------------------------------------+ //|Check the conditions for opening a long position (Buy) | //+------------------------------------------------------------------+ Boolean value CSignal3EMA::CheckOpenLong( double & price, double & SL, double & TP, date time and validity period) { Double mid = mid EMA( 1 ); //--- price = 0.0 ; sl =m_symbol.Ask()-m_stop_loss*m_adjusted_point; tp =m_symbol.Ask()+m_take_profit*m_adjusted_point; //--- Check the uptrend (on the last completed bar): FastEMA(1)>MediumEMA(1)>SlowEMA(1) returns (FastEMA( 1 )>Medium&& Medium>SlowEMA( 1 )); }
2. Long position closing
Downtrend is determined by: FastEMA 3. Open a short position 4. Close position You can improve closing: you do not have to wait for the uptrend, you can close the position when it is closed, which can be determined by: FastEMA>MediumEMA Create an Expert Advisor using the MQL5 Wizard To create a trading robot based on a strategy, you need to select the signal property as " Signal based on three EMAs " in the "Create ready-made Expert Advisor" option in the MQL5 Wizard : Figure 2. Selecting "Signal based on three EMAs" in the MQL5 Wizard Next you must specify the required trailing stop algorithm and money and risk management system. The code of the Expert Advisor will be automatically created and you can compile and test it with the Strategy Tester MetaTrader 5 client terminal. Test results Let's consider back testing the Expert Advisor based on historical data (EURUSD H1, testing period: January 1, 2010 to January 5, 2011, FastPeriod=5, MediumPeriod=12, SlowPeriod=24, StopLoss=400, TakeProfit=900). When creating the EA, we used a fixed trading volume ( fixed lot size for trading , 0.1) and did not use the trailing stop algorithm ( trailing was not used ). Figure 3. Historical backtest results of EA trading (based on three EMAs) Attachment: Signal3EMA.mqh with CSignal3EMA class must be placed into terminal_data_folder\MQL5\Include\Expert\Signal.

{
Doubled Medium = MediumEMA( 1 ); //--- Price = 0.0 ; //--- Check the uptrend (on the last completed bar): FastEMA(1)>MediumEMA(1)>SlowEMA(1) returns (FastEMA( 1 )>Medium && Medium>SlowEMA( 1 ));
