## Overview
This expert advisor script is designed to automate trading on MetaTrader 4/5 platforms. The trading logic is based on a simple Moving Average Crossover Strategy. It analyses short-term and long-term moving averages to determine buy or sell signals and executes trades accordingly. The script also handles initialization, deinitialization, and error logging during its operation.

## Components
### OnInit
```cpp
int OnInit()
{
// Initialize any global or static variables here
// Setup any necessary configurations or parameters
return(INIT_SUCCEEDED);
}
```
- This function initializes the necessary configurations and variables when your Expert Advisor (EA) starts. It returns `INIT_SUCCEEDED` if the initialization is successful.
### OnDeinit
```cpp
void OnDeinit(const int reason)
{
// Clean up any resources or states initialized during OnInit
}
```
- This function cleans up any resources or states that were initialized in the `OnInit` function when the EA stops.
### OnTick
```cpp
void OnTick()
{
// Main logic to be executed on every tick
// E.g., Opening, modifying, or closing positions based on conditions
CheckTradingConditions();
}
```
- This function contains the main logic that gets executed on every new market tick. It calls the `CheckTradingConditions()` function to evaluate trading signals.
### CheckTradingConditions
```cpp
void CheckTradingConditions()
{
// Example: Simple Moving Average Crossover Strategy
double shortSMA = iMA(NULL, 0, 14, 0, MODE_SMA, PRICE_CLOSE, 0);
double longSMA = iMA(NULL, 0, 50, 0, MODE_SMA, PRICE_CLOSE, 0);
// Cross above: Buy Signal
if (shortSMA > longSMA && PositionSelect(_Symbol) == false)
{
// Place a buy order
ExecuteTrade(ORDER_TYPE_BUY);
}
// Cross below: Sell Signal
else if (shortSMA < longSMA && PositionSelect(_Symbol) == true)
{
// Close previous buy order
ExecuteTrade(ORDER_TYPE_SELL);
}
}
```
- This function checks the trading conditions based on a Simple Moving Average (SMA) Crossover Strategy. It compares the short-term SMA with the long-term SMA to generate buy or sell signals.
### ExecuteTrade
```cpp
void ExecuteTrade(int orderType)
{
MqlTradeRequest request;
MqlTradeResult result;
MqlTick last_tick;
// Fill in the request structure
ZeroMemory(request);
request.action = TRADE_ACTION_DEAL;
request.magic = 123456; // Unique identifier for expert trades
request.symbol = _Symbol;
request.volume = 0.1; // Trade volume, e.g., 0.1 lots
SymbolInfoTick(_Symbol, last_tick);
request.price = (orderType == ORDER_TYPE_BUY) ? last_tick.ask : last_tick.bid;
request.type = orderType;
request.deviation = 10; // Allowable slippage in points
// Set stop loss and take profit (optional)
if(orderType == ORDER_TYPE_BUY)
{
request.sl = last_tick.bid - 100 * _Point; // 100 points stop loss
request.tp = last_tick.bid + 200 * _Point; // 200 points take profit
}
else if(orderType == ORDER_TYPE_SELL)
{
request.sl = last_tick.ask + 100 * _Point; // 100 points stop loss
request.tp = last_tick.ask - 200 * _Point; // 200 points take profit
}
// Send the trade request
if(!OrderSend(request, result))
{
// Handle any errors during the trade request
Print(OrderSend failed: , GetLastError());
}
else
{
// Confirm the trade was successful
Print(Trade successfully executed: Ticket# , result.deal);
}
}
```
- This function handles trade execution. It fills in the trade request structure, sets parameters like price, volume, stop loss, and take profit, and sends the trade request. If the trade fails, it logs an error message.
### PrintError
```cpp
void PrintError(const string msg)
{
// Outputs error message to the Experts tab
Print(Error: , msg);
}
```
- This function handles error logging. It prints error messages to the Experts tab for debugging purposes.
### Main Script
```cpp
void Start()
{
// If the script is run manually, this can be the main function to start trading
while(true)
{
OnTick();
Sleep(1000); // Pause execution for 1 second
}
}
```
- This function is a main loop that continuously calls `OnTick()` and pauses execution for 1 second. It mainly serves as a manual start point for the script.
