Boom and Crash Smasher EA: Trade Explosive Signals

Introduction

Hey there, future forex firestarter! Picture the forex market as a fireworks display, with prices bursting in wild spikes and crashes. The Boom and Crash Smasher EA is your match, using a custom “Boom and Crash Smasher” indicator to light up buy and sell signals in high-volatility markets like Boom and Crash indices. This article is your pyrotechnic manual, guiding you through the MQL5 code on MetaTrader 5 with vivid detail. We’ll explain every major function like you’re new to coding (no shade!), blending humor and flow like a storyteller at a bonfire. By the end, you’ll be ready to let this Expert Advisor (EA) ignite trades for you. Let’s spark some profits!

Strategy Blueprint

The Boom and Crash Smasher EA relies on a custom indicator tailored for volatile instruments. While the indicator’s logic is proprietary, it outputs:

• Buy Signal: A positive value (>0) signaling a potential upward spike.

• Sell Signal: A positive value (>0) indicating a potential downward crash.

The EA buys at the ask price on a buy signal, using a 0.01-lot size, a 400-pip stop loss, and a 100-pip take profit. It sells at the bid price on a sell signal with the same setup. Trades execute only on new candles to avoid duplicates, ensuring discipline. The strategy targets rapid, short-term moves in volatile markets, like catching a firework’s burst before it fades. See below.

Code Implementation

Let’s dive into the MQL5 code like pyrotechnicians prepping a fireworks show, crafting a narrative that flows seamlessly from setup to trading. We’ll present each major function in full, explaining every key function in detail for clarity, and quoting variables (e.g., "smasherBuy") and functions (e.g., "OnInit()") to keep it beginner-friendly. Our goal is to make the code as inviting as a glowing sparkler, guiding you through every step with ease.

Lighting the Fuse: Header, Includes, and Global Variables

We start by setting up the launch pad, like prepping a firework before ignition.

#property version   "1.00"

#include <Trade/Trade.mqh>
CTrade obj_Trade;

int handleBoom_and_CrashSmasher;

int totalBars = 0;

This opening sets the stage. The header declares the EA as “BOOM AND CRASH SMASHER EA,” crafted by Allan in 2025, with a link to your Telegram channel and version 1.00. The #include <Trade/Trade.mqh> directive imports the MQL5 trade library, enabling trade execution. The "CTrade" class creates an object named "obj_Trade", your trading assistant for opening buy and sell orders.

Globally, we define:

• "handleBoom_and_CrashSmasher": An integer to store the custom indicator’s handle, like a fuse for accessing signal data.

• "totalBars": An integer tracking the number of chart bars, ensuring trades only trigger on new candles.

These globals are like your firework kit, ready for the EA to light up the market.

Igniting the Setup: OnInit Function

Next, we load the custom indicator, like priming a firework for launch.

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
{
   handleBoom_and_CrashSmasher = iCustom(_Symbol,_Period,
                           "Market//Boom and crash smasher");
   return(INIT_SUCCEEDED);
}

The "OnInit()" function is the EA’s pre-launch checklist, running when you attach it to a chart. Key function:

• "iCustom()": Loads the “Boom and crash smasher” custom indicator from the “Market” folder for the current symbol ("_Symbol", e.g., Boom 1000 Index) and timeframe ("_Period", e.g., M5). It returns a handle, stored in "handleBoom_and_CrashSmasher", for accessing signal data.

• INIT_SUCCEEDED: A constant signaling successful initialization, returned here as no error checking is implemented (see notes).

This function ensures the indicator is loaded, like lighting the fuse before the show. It’s minimal but effective, assuming the indicator is correctly installed.

Extinguishing the Flame: OnDeinit Function

When the show ends, this function tidies up.

//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
{
}

The "OnDeinit()" function is the EA’s cleanup crew, called when you remove it from the chart. It’s empty, like a launch site left spotless. No cleanup is needed since the indicator and trades are managed by MetaTrader 5, keeping things lightweight.

Launching the Fireworks: OnTick Function

Now we hit the EA’s core, where it trades explosive signals on every price tick.

//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
{
   double
         Ask = NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits),
         Bid = NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_BID),_Digits);
         
   double smasherSell[];
   ArraySetAsSeries(smasherSell,true);
   CopyBuffer(handleBoom_and_CrashSmasher,0,0,2,smasherSell);
   
   double smasherBuy[];
   ArraySetAsSeries(smasherBuy,true);
   CopyBuffer(handleBoom_and_CrashSmasher,1,0,2,smasherBuy);
   
   int bars = iBars(_Symbol,_Period);
   if (totalBars == bars) return;
   totalBars = bars;
   
   if (smasherBuy[1] > 0){
      Print("BUY SIGNAL");
      obj_Trade.Buy(0.01,_Symbol,Ask,Ask-400*_Point,Ask+100*_Point);
   }
   else if (smasherSell[1] > 0){
      Print("SELL SIGNAL");
      obj_Trade.Sell(0.01,_Symbol,Bid,Bid+400*_Point,Bid-100*_Point);
   }
}

The "OnTick()" function is the EA’s fireworks launch, running on every price tick to trade volatile signals. It’s the heart of the strategy, so let’s unpack it with detail, explaining each major function:

• "SymbolInfoDouble()": Retrieves real-time market data, grabbing the ask price ("SYMBOL_ASK") for buying and bid price ("SYMBOL_BID") for selling, stored in "Ask" and "Bid".

• "NormalizeDouble()": Rounds prices (e.g., "Ask", "Bid") to the symbol’s decimal places ("_Digits", e.g., 2 for Boom indices), ensuring trade-ready formatting.

• "ArraySetAsSeries()": Configures the "smasherBuy[]" and "smasherSell[]" arrays as time series, so index 0 holds the latest value, like sorting your firework triggers newest first.

• "CopyBuffer()": Copies data from the custom indicator (via "handleBoom_and_CrashSmasher") into arrays. It pulls two values from buffer 0 (sell signals, "smasherSell[]") and buffer 1 (buy signals, "smasherBuy[]"). No error checking is implemented (see notes).

• "iBars()": Returns the number of bars on the chart, stored in "bars", to check for new candles.

• Bar Check Logic: If "totalBars" equals "bars", the EA skips to avoid reprocessing the same candle. When a new bar forms, "totalBars" updates, ensuring trades trigger only on fresh candles.

• "Print()": Logs a message to the MetaTrader 5 journal, announcing “BUY SIGNAL” or “SELL SIGNAL” when triggered.

• Buy Signal Logic: If the previous candle’s buy signal is positive ("smasherBuy[1] > 0"), the EA logs “BUY SIGNAL” and opens a buy trade with "obj_Trade.Buy()", using 0.01 lots, "Ask" price, a 400-pip stop loss ("Ask-400*_Point"), and a 100-pip take profit ("Ask+100*_Point").

• Sell Signal Logic: If the previous candle’s sell signal is positive ("smasherSell[1] > 0"), the EA logs “SELL SIGNAL” and opens a sell trade with "obj_Trade.Sell()", using 0.01 lots, "Bid" price, a 400-pip stop loss ("Bid+400*_Point"), and a 100-pip take profit ("Bid-100*_Point").

• "Buy()", "Sell()": Methods of the "CTrade" class, opening buy or sell trades with parameters like lot size (0.01), symbol ("_Symbol"), price, stop loss, and take profit.

• "_Point": A built-in variable for the symbol’s pip size, used to calculate stop loss and take profit distances.

This function flows from fetching prices and signals to checking for new candles and executing trades, like launching a firework at the perfect moment.

Putting It All Together

To unleash this EA:

1. Ensure the “Boom and crash smasher” indicator is in the MetaTrader 5 “Market” folder.
