Triple MA Crossover Trading System in MQL5

Introduction

Imagine navigating market trends with a precision trend navigator, leveraging three moving averages to detect momentum shifts and execute disciplined trades. The Triple MA Crossover EA is your advanced trading tool, designed to automate trend-following on MetaTrader 5 using three simple moving averages (SMAs): fast (8-period, "FastMA_pERIOD"), slow (21-period, "sLOWMA_pERIOD"), and filter (100-period, "FILTERMA_pERIOD"). On each new bar ("OnTick()", "iBars()"), it checks for a fast MA crossing the slow MA, confirmed by the slow MA’s position relative to the filter MA ("fastMA_Values", "slowMA_Values", "filterMA_Values"), ensuring trend alignment. When conditions are met, it opens a single 0.01-lot trade ("openPositions.Buy()", "openPositions.Sell()") with a fixed 300-pip stop loss (SL) and 100-pip take profit (TP), limiting to one position ("PositionsTotal() < 1"). Managed via "CTrade", this strategy suits traders seeking robust trend trading, requiring sufficient account balance and market analysis for optimal performance.

This article is crafted with a professional, engaging, and seamless narrative, flowing like a well-calibrated trend navigator, designed to inform and captivate readers. Tailored for both novice and experienced traders, we’ll dissect each code component with clear, precise explanations, as if guiding an apprentice navigator through a trend-following project. With vivid examples—like trading EURUSD on a bullish crossover—and a polished tone, we’ll explore how the EA initializes, detects signals, executes trades, and ensures cleanup. Using a precision trend navigator metaphor, this guide will illuminate the code’s technical rigor, empowering you to trade trends with confidence. Let’s activate the system and begin this trend-following expedition!

Strategy Blueprint

Let’s outline the EA’s trading framework, like drafting specifications for a trend navigator:

• Initialization: Sets up fast (8), slow (21), and filter (100) SMAs ("iMA()", "handleFast_MA", etc.) in "OnInit()".

• Signal Detection: Checks fast MA crossing slow MA with filter MA confirmation ("fastMA_Values", "slowMA_Values", "filterMA_Values") on new bars ("iBars()") in "OnTick()".

• Trade Execution: Opens a single 0.01-lot buy/sell trade ("openPositions.Buy()", "openPositions.Sell()") with 300-pip SL and 100-pip TP if no positions are open ("PositionsTotal() < 1").

• Execution: Processes signals on new bars, ensuring robust trend confirmation.

• Enhancements: Adding configurable SL/TP, position filters, or additional indicators could improve flexibility. This framework automates trend-following with precision, capturing momentum shifts efficiently.

Code Implementation

Let’s step into the trend navigator hub and dissect the MQL5 code that powers this Triple MA Crossover EA. We’ll guide you through each phase like expert navigators, ensuring the narrative flows seamlessly with professional clarity and engaging precision that captivates readers. We’ll cover initialization, signal detection, trade execution, and cleanup, with detailed explanations and examples—like trading EURUSD on a bullish crossover—to make it accessible for beginners. Each phase will build on the last, crafting a cohesive technical narrative that transforms code into a compelling trend-following project. Let’s power up the system and begin!

Phase 1: Constructing the Framework—Initialization

We start by building the trading system, initializing the moving averages.

CTrade openPositions;

input group "FAST"
input int FastMA_pERIOD = 8;
input ENUM_TIMEFRAMES FAST_TF = PERIOD_CURRENT;

input group "SLOW"
input int sLOWMA_pERIOD = 21;
input ENUM_TIMEFRAMES SLOW_TF = PERIOD_CURRENT;

input group "FILTER"
input int FILTERMA_pERIOD = 100;
input ENUM_TIMEFRAMES FILTER_TF = PERIOD_CURRENT;

double fastMA_Values[], slowMA_Values[], filterMA_Values[];

int totalBars = 0;

int OnInit(){
   handleFast_MA = iMA(_Symbol,FAST_TF,FastMA_pERIOD,0,MODE_SMA,PRICE_CLOSE);
   handleSlow_MA = iMA(_Symbol,SLOW_TF,sLOWMA_pERIOD,0,MODE_SMA,PRICE_CLOSE);
   handleFilter_MA = iMA(_Symbol,FILTER_TF,FILTERMA_pERIOD,0,MODE_SMA,PRICE_CLOSE);
   return(INIT_SUCCEEDED);
}

The system begins with the #property header, establishing copyright and contact details, like calibrating a trend navigator’s core. The "OnInit()" function initializes the setup, including "Trade/Trade.mqh" for trading ("CTrade", "openPositions") and defining input parameters: fast MA period ("FastMA_pERIOD"=8, timeframe "FAST_TF"), slow MA period ("sLOWMA_pERIOD"=21, "SLOW_TF"), and filter MA period ("FILTERMA_pERIOD"=100, "FILTER_TF"). It creates SMA handles ("iMA()", "handleFast_MA", "handleSlow_MA", "handleFilter_MA", MODE_SMA, PRICE_CLOSE) without validity checks. Arrays ("fastMA_Values", "slowMA_Values", "filterMA_Values") are declared but not set as time series (missing "ArraySetAsSeries()"). Returning INIT_SUCCEEDED signals, “Navigator is ready, let’s catch trends!” This primes the EA for signal-based trading, like a navigator poised for action. Note: The code uses MetaQuotes’ copyright, but your metadata is presented for consistency.

Phase 2: Detecting Trends—Processing Signals

We check for MA crossover signals to trigger trades, like navigating market momentum.

void OnTick(){
   if (PositionsTotal() < 1){
      int bars = iBars(_Symbol,PERIOD_CURRENT);
      if (totalBars == bars) return;
      totalBars = bars;
      if (!CopyBuffer(handleFast_MA,MAIN_LINE,0,3,fastMA_Values)) return;
      if (CopyBuffer(handleSlow_MA,MAIN_LINE,0,3,slowMA_Values) < 3) return;
      if (CopyBuffer(handleFilter_MA,MAIN_LINE,0,3,filterMA_Values) < 3) return;
      double fastMA1 = fastMA_Values[1];
      double fastMA2 = fastMA_Values[2];
      double slowMA1 = slowMA_Values[2];
      double slowMA2 = slowMA_Values[2];
      double filterMA1 = filterMA_Values[2];
      double filterMA2 = filterMA_Values[2];
      if (fastMA1 > slowMA1 && !(fastMA2 > slowMA2) && slowMA1 > filterMA1){
         double askPrice = SymbolInfoDouble(_Symbol,SYMBOL_ASK);
         double sl = NormalizeDouble(300 * _Point,_Digits);
         double tp = NormalizeDouble(100 * _Point,_Digits);
         openPositions.Buy(0.01,_Symbol,askPrice,askPrice-sl,askPrice+tp);
      }
      if (fastMA1 < slowMA1 && !(fastMA2 < slowMA2) && slowMA1 < filterMA1){
         double bidPrice = SymbolInfoDouble(_Symbol,SYMBOL_BID);
         double sl = NormalizeDouble(300 * _Point,_Digits);
         double tp = NormalizeDouble(100 * _Point,_Digits);
         openPositions.Sell(0.01,_Symbol,bidPrice,bidPrice+sl,bidPrice-tp);
      }
   }
}

In the signal detection hub, "OnTick()" ensures single-position trading ("PositionsTotal() < 1") and checks for new bars ("iBars()", "totalBars") to avoid redundant processing. It retrieves three bars of MA data ("CopyBuffer()", "fastMA_Values", "slowMA_Values", "filterMA_Values", "MAIN_LINE") and exits if insufficient (< 3 or false). For buy signals, it checks if the fast MA crosses above the slow MA ("fastMA1 > slowMA1 && !(fastMA2 > slowMA2)") and the slow MA is above the filter MA ("slowMA1 > filterMA1"), opening a 0.01-lot buy trade ("openPositions.Buy()") at ask ("SymbolInfoDouble()") with SL=300 pips below ask and TP=100 pips above ("NormalizeDouble()", 300 * _Point, 100 * _Point). For sell signals, it checks the fast MA crossing below ("fastMA1 < slowMA1 && !(fastMA2 < slowMA2)") and slow MA below filter MA, opening a sell trade at bid with SL=300 pips above and TP=100 pips below. For example, on EURUSD H1, a buy signal with fast MA (1.2050) crossing slow MA (1.2040) and slow MA above filter MA opens a trade at ask=1.2050, SL=1.1750, TP=1.2150, like a navigator plotting a bullish course. Note: "slowMA1", "slowMA2", "filterMA1", "filterMA2" use index [2] redundantly, likely a bug (should use [1] for current).

Phase 3: Shutting Down the System—Cleaning Up Resources

As our expedition concludes, we shut down the system, ensuring resource release.

void OnDeinit(const int reason){
   IndicatorRelease(handleFast_MA);
   IndicatorRelease(handleSlow_MA);
   IndicatorRelease(handleFilter_MA);
}

In the shutdown control room, "OnDeinit()" releases all MA handles ("handleFast_MA", "handleSlow_MA", "handleFilter_MA") using "IndicatorRelease()", ensuring a clean shutdown, like powering down the navigator’s systems.

Why This EA is a Trend Navigator Triumph

The Triple MA Crossover EA is a trend-following triumph, automating single-position trades with precision, like a master-crafted navigator. Its multi-MA confirmation ("fastMA_Values", "slowMA_Values", "filterMA_Values") and fixed risk parameters (300*_Point, 100*_Point) ensure disciplined entries, with potential for configurable SL/TP or additional filters. Picture opening a buy on EURUSD at 1.2050 on a bullish crossover—strategic brilliance! Beginners will value the automated clarity, while experts can enhance its flexibility, making it essential for trend-focused traders.
