MQL5 Wizard - Trading signals based on Morning Star/Evening Star + RSI - MetaTrader 5 Expert

CheckCandlestickPattern(CANDLE_PATTERN_EVENING_STAR) and CheckCandlestickPattern(CANDLE_PATTERN_EVENING_DOJI) methods CC Candlestick Pattern class are used to check the formation of "Evening Star" and "Evening Doji Star" candlestick patterns.

2. Trading signals, confirmed by the RSI indicator

The closing of an open position depends on the following values ​​of the Relative Strength Index . This can be done in two situations:

Figure 3. “Morning Star” pattern confirmed by RSI indicator

2.1. Open long position/close short position

The formation of the "Morning Star" pattern must be determined by the relative strength index indicator: RSI(1)<40 (the RSI value of the last completed bar must be less than 40).

Short positions must be closed if the RSI indicator breaks above the key levels of 70 or 30.

//+------------------------------------------------------------------+
//|Check the conditions for entering and exiting the market |
//| 1) Enter the market (open long position, result = 80) |
//| 2) Market Exit (Close Position, Result=40) |
//+------------------------------------------------------------------+
integerCMS_ES_RSI ::longcondition()
  {
Integer result = 0 ; //--- idx can be used to determine the Expert Advisor working mode
//--- idx=0 - in this case the EA checks the trading conditions on every price move
//--- idx=1 - in this case the EA only checks the trading status of the news bar integer idx =StartIndex(); //--- checks the conditions for opening a long position
//--- Morning star pattern is formed and RSI < 30 if (check candlestick pattern (CANDLE_PATTERN_MORNING_STAR) && (RSI( 1 ) < 40 ))
    Result = 80 ; //--- check closing conditions
//--- Signal line crossover for overbought/oversold levels (up 30, up 70) if (((RSI( 1 )> 30 ) && (RSI( 2 )< 30 )) || ((RSI( 1 )> 70 ) && (RSI( 2 )< 70 )))
    result = 40 ; //--- return result return (result);
  }

2.2. Open short position/close long position

The formation of the "Evening Star" pattern must be determined by the relative strength index indicator: RSI(1)>60 (the RSI indicator value of the final completion bar must be greater than 60).

Long positions must be closed if the RSI indicator crosses below the key levels of 70 or 30.

 //+------------------------------------------------------------------+
//|Check the conditions for entering and exiting the market |

//| 2) Market Exit (Close Position, Result=40) |
//+------------------------------------------------------------------+
Integer CMS_ES_RSI::ShortCondition()
  {
Integer result = 0 ; //--- idx can be used to determine the Expert Advisor working mode
//--- idx=0 - in this case the EA checks the trading conditions on every price move
//--- idx=1 - in this case the EA only checks the trading status of the news bar integer idx =StartIndex(); //--- checks the conditions for opening a short position
//--- formation of Evening Star pattern and RSI > 60 if (check Candlestick Pattern (CANDLE_PATTERN_EVENING_STAR) && (RSI( 1 ) > 60 ))
    Result = 80 ; //--- check closing conditions
//--- Signal line crossover of overbought/oversold levels (down 70, down 30) if (((RSI( 1 )< 70 ) && (RSI( 2 )> 70 )) || ((RSI( 1 )< 30 ) && (RSI( 2 )> 30 )))
    result = 40 ; //--- return result return (result);
  }

2.3. Use the MQL5 Wizard to create an Expert Advisor

The CMS_ES_RSI class is not included in the standard library classes, to use it you need to download the acms_es_rsi.mqh file (see attachment) and save it to client_terminal_data_folder\MQL5\Include\Expert\Signal\MySignals. The same operation should be performed for the candlepatterns.mqh file. After restarting MetaEditor, you can use it in the MQL5 Wizard.

Create Expert Advisor Launch MQL5 Wizard :

Figure 4. Creating an Expert Advisor using the MQL5 Wizard

Let's specify the name of the Expert Advisor:

Figure 5. General properties of EA trading

After that we need to choose the trading signal module to use.

Figure 6. Signal properties of EA trading

In our case we use only one trading signals module.

Figure 7. Signal properties of EA trading

Added trading signals module:

Figure 8. Signal properties of EA trading

You can choose any trailing attribute, but we will use "Unused Trailing Stop":

Figure 9. Tracking properties of Expert Advisor

Regarding the money management properties, we will use "Fixed Volume Trading":

Figure 10. Money management attributes of EA trading

By pressing the "Finish" button we will get the code of the generated Expert Advisor in Expert_AMS_ES_RSI.mq5, which will be saved in terminal_data_folder\MQL5\Experts\.

Default input parameters of the generated Expert Advisor:

 //--- Main signal input
Input integer Signal_ThresholdOpen = 10 ; //Open signal threshold[0...100]
Input integer Signal_ThresholdClose = 10 ; // Close signal threshold [0...100]
Enter double Signal_PriceLevel = 0.0 ; // price level at which to execute the trade
Enter double Signal_StopLevel = 50.0 ; // Stop loss level in pips
Enter double Signal_TakeLevel = 50.0 ; // Take profit level (in pips)

Must be replaced with:

//--- Main signal input
Input integer Signal_ThresholdOpen = 40 ; //Open signal threshold[0...100]
Input integer Signal_ThresholdClose = 20 ; // Close signal threshold [0...100]
Enter double Signal_PriceLevel = 0.0 ; // price level at which to execute the trade
Enter double Signal_StopLevel = 0.0 ; // Stop loss level in points
Enter double Signal_TakeLevel = 0.0 ; // Take profit level (in pips)

Signal_ThresholdOpen/Signal_ThresholdClose input parameters allow specifying threshold levels for opening and closing positions.

In the code of the LongCondition() and ShortCondition() methods of the trading signal class, we specify the fixed value of the threshold:

The Expert Advisor generates opening and closing positions by the MQL5 Wizard using "votes" in the Trading Signals module. The vote of the main module (which acts as a container and consists of all added modules) is also used, but its LongCondition() and ShortCondition() methods always return 0.

The voting results from the main module are also used for "voting" averaging. In our case we have: main module + 1 trading signals module, so we need to take this fact into account when setting the thresholds. Therefore, ThresholdOpen and ThresholdClose must be set to 40=(0+80)/2 and 20=(0+40)/2.

The value of the Signal_StopLevel and Signal_TakeLevel input parameters is set to 0, which means that the position will be closed only if the closing conditions are met.

2.4. Historical backtest results

Let us consider the EA trading backtest on historical data (EURUSD H1, test period: 2010.01.01-2011.03.04, PeriodK=47, PeriodD=9, PeriodSlow=13, MA_period=5).

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 11. EA trading test results based on Morning Star/Evening Star + RSI

The best set of input parameters for the Strategy Tester MetaTrader 5 client can be found using the following command.

The study strategy of parameters is greatly simplified using the following formula 3D visualization mode of the tester , added starting from version 419 (Fig. 12):

The code for the Expert Advisor created by the MQL5 Wizard is attached in Expert_ms_es_rsi.mq5.
