A GUI-based calculator for Forex trading using the MT5 platform. It currently includes the following functions:

• Entry and execution of a trade order
  • Includes entry of a stop loss, takeprofit, percentage risk, deviation and entry price for pending orders
• A function that automatically sets the take profit to be a desired risk : reward ratio
• Placement of pending orders including Buy / Sell limits and stops
• An automatic calculation of volume based on the chosen risk, the entered stop loss and entry price
• Ability to open a double order instantly
• Functions that return both open positions and pending orders respectively
• The ability to instantly close all open positions in their entirety
• The ability to close half or a desired percentage of open positions. This will soon take a position ID as input to select a single position to enact these changes
• Instantly cancel all pending orders or select a specific order to cancel via its position ID
• A function to halve the risk of an order
• A 'runner' function that instantly sets the stop loss a few points above break even, it closes 80% of the open position and increases the take profit level
• Auto break even function sets an orders stop loss a few points above the inital entry price. Currently not 'automatic'

I also need to fully implement the selection of a position ID for the corresponding functions.
