The provided MQL4 code is for a trading expert advisor that performs stop-loss (SL) and take-profit (TP) adjustments on open positions in MetaTrader 4. Below, I'll explain the key components of this code:
Key Components
-
Initialization Functions:
init(): Initializes variables such as the minimum distance for SL/TP (Min_Dist) and flags to control working states (Work,New_SL,Close_TF).- Global variables are declared at the beginning, which include configurations like
Slippageand booleans to manage different operational modes.
-
Deinitialization Function:
deinit(): Resets some of the global flags (New_SL,Close_TF) when the EA is uninstalled or stops running.
-
Timer Event Handler:
OnTimer()handles periodic execution based on specified intervals.- It processes open positions to check if they are pending (i.e., waiting for a new SL/TP) and updates these values accordingly using
OrderModify.
-
Trade Management Functions:
Open_Condition(): Determines conditions under which an order can be opened based on several criteria like price trends, custom indicators (sma,ema), RSI levels, etc.Stop_loss()andTake_profit(): Calculate new SL and TP values for open positions.
-
Order Modification:
- Uses the
OrderModifyfunction to adjust the SL and TP of existing orders based on market conditions evaluated during each timer tick.
- Uses the
-
Error Handling:
- The
New_Stop()function ensures that SL/TP adjustments respect minimum distance requirements set by the broker.
- The
-
Utility Functions:
- Functions like
Close_Trend()are used for additional checks or processing, although their implementation is not fully shown here. - The
MyPrint()function logs messages to the MetaTrader console, which is useful for debugging and monitoring EA activity.
- Functions like
Important Considerations
-
Slippage Handling: Slippage is set explicitly in orders, which can be adjusted as needed based on trading conditions or broker settings.
-
Dynamic Adjustment:
- The EA adjusts SL/TP dynamically based on market volatility using the Average True Range (ATR) indicator. This allows for flexible risk management tailored to current market conditions.
-
Indicators and Custom Conditions: It uses custom indicators (
sma,ema) and RSI levels as part of its logic, which are common tools in technical analysis to determine trend strength and momentum. -
Debugging and Monitoring:
- Extensive use of the
MyPrintfunction provides insights into what conditions are met or not during EA execution. This is valuable for understanding the behavior of the strategy over time.
- Extensive use of the
Example Explanation
Let's take a closer look at the OnTimer() function logic:
-
Order Iteration: It iterates through all open positions and checks if they need SL/TP adjustments.
-
Pending Orders Check: The EA specifically looks for orders with pending actions (
ORDER_ACTION_PENDING) to modify them. -
Modification Logic:
- Calculates new TP using the
Take_profit()function, which factors in market conditions like RSI levels and current price trends. - Adjusts SL based on recent volatility (ATR) or other criteria defined in the strategy logic.
- Calculates new TP using the
-
Market Conditions: The EA considers market trends and direction changes to decide whether to adjust or close positions.
This code exemplifies a complex trading bot that manages open positions dynamically, adjusting risk parameters in response to market behavior. It requires careful testing and optimization for different assets and market conditions to ensure robust performance.
