Pending orders DOWN - MetaTrader 5용 스크립트

The "Pending orders DOWN" script sets a grid of orders below the current price.

Input Parameters

• Gap for pending orders DOWN from the current price (in pips) - the distance from the current price to place the first pending order.
• Step between orders DOWN (in pips) - distance between pending orders.
• Type of pending orders DOWN - the type of the pending order (can be either Buy Limit or Sell Stop).
• DOWN quantity - the number of orders to be placed.
• Lots - the volume of each order.
• Stop Loss (in pips) - Stop Loss value.
• Take Profit (in pips) - Take Profit value.

The script ensures the fastest possible sending of trade requests to place pending orders due to the use of the asynchronous mode of trading operations:

   m_trade.SetAsyncMode(true);

Here is an example of sending requests for five pending orders:
