Pending orders UP - script for MetaTrader 5

The "Pending orders UP" script sets a grid of orders above the current price.

Input Parameters

• Gap for pending orders UP from the current price (in pips) - the distance from the current price to place the first pending order.
• Step between orders UP (in pips) - distance between pending orders.
• Type of pending orders UP - the type of the pending order (can be either Buy Stop or Sell Limit).
• UP 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:
