Explanation:

1. Inputs:

   • LotSize: The size of the lot to trade.
   • PendingPrice: The price at which the pending order will be placed.
   • StopLoss: The price at which the stop loss will be set.
   • TakeProfit: The price at which the take profit will be set.
   • Slippage: The maximum slippage allowed in pips.
   • IsBuyLimit: A boolean flag to determine whether the order is a Buy Limit (true) or a Sell Limit (false).

2. OnInit() Function:

   • This function initializes the expert advisor. It checks if there are enough funds to place the order using AccountFreeMarginCheck.
   • It determines the order type (OP_BUYLIMIT or OP_SELLLIMIT) based on the IsBuyLimit input.
   • If there are enough funds, it places a pending order using OrderSend.
   • If the order is placed successfully, it prints the ticket number; otherwise, it prints an error message.

3. OnDeinit() Function:

   • This function is called when the expert advisor is removed. It is left empty in this example.

4. OnTick() Function:

   • This function is called on every tick. It is also left empty in this example.

How to use:

1. Open the MetaEditor from MetaTrader 4.
2. Create a new Expert Advisor and paste the code above into the editor.
3. Save and compile the code.
4. Attach the compiled EA to a chart in MetaTrader 4.

Customization:

• Modify the input parameters (LotSize, PendingPrice, StopLoss, TakeProfit, Slippage, IsBuyLimit) as needed before attaching the EA to the chart.
• This script will place a pending order (Buy Limit or Sell Limit) with the specified parameters when the EA is initialized.
