Crate ea on pending order mt4 and mt5 both platforms

Creating an expert advisor (EA) in the MetaTrader 4 & 5 (MT4/ MT5) platform involves several steps, including defining input parameters, writing the logic for trading operations, and handling order management. Let's break down each point with a full explanation:

1. **Input Parameters:**

   - **Lot Type (LotType):** This parameter allows the user to choose between a fixed lot size or an automatic lot size. If set to "fix," the EA will use a fixed lot size specified by the user. If set to "auto," the EA will calculate the lot size based on the user's equity and the specified lot amount.

   - **Lot Amount (LotAmount):** This parameter specifies the amount per lot for automatic lot sizing. For example, if the user sets it to 100$, the EA will calculate the lot size based on the equity and this amount. If the equity is 300$, the EA will open a 0.03 lot size.

   - **Lot (Lot):** This parameter defines the fixed lot size to be used if Lot Type is set to "fix."

   - **Order Gap (OrderGap):** This parameter determines the distance in pips from the current market price at which the EA will place buy stop and sell stop orders.

   - **Take Profit (TP):** The take profit level in pips.

   - **Stop Loss (SL):** The stop loss level in pips. If set to 0, it means no stop loss will be used.

   - **Trailing Stop Loss (TSL):** This parameter activates or deactivates the trailing stop loss feature. A value of 1 enables the trailing stop loss, while 0 disables it.

   - **EA Name (EAName):** The name of the expert advisor. This name will be displayed in the comment section of trading history and the terminal.

2. **Logic for Trading Operations:**

   - The EA will run continuously and execute its logic on each tick received from the market.

   - It will calculate the lot size based on the input parameters and the user's equity, considering whether the lot type is fixed or automatic.

   - Buy stop and sell stop orders will be placed at a specified distance from the current market price (Order Gap).

   - Take profit and stop loss levels will be set according to the input parameters.

   - If the trailing stop loss feature is enabled, the EA will adjust the stop loss level dynamically as the trade moves in the desired direction.

3. **Order Management:**

   - The EA will manage pending orders by canceling existing ones before placing new ones.

   - It will monitor the status of trades, adjusting stop loss and take profit levels as necessary.

   - The EA will handle error conditions gracefully, providing feedback in the terminal if any issues occur during order placement or modification.

4. **User Interaction:**

   - Users can interact with the EA by setting input parameters according to their trading preferences.

   - The EA name parameter allows users to identify the EA in the trading history and terminal comments.

By implementing these features, the expert advisor will provide users with a flexible and automated trading solution, capable of managing pending orders effectively based on the specified input parameters.
