Modify Simple Trade Panel

Hello guys. I am not a programmer but I was hoping I could get some assistance with making some adjustments to the default code in Ctrader for the simple trade panel. 

1: Is it possible to modify the code so that it accepts the price instead of the pips for the stop loss?

2: Could the code be modified to auto calculate the lot size based on the distance from price ? 

If anyone is willing to tell help please advise on where I can make these changes in the code and what change I need to make. I really need the help.

The default code is posted below. 

using System;
using System.Collections.Generic;
using cAlgo.API;
using cAlgo.API.Internals;

        [Parameter("Horizontal Position", Group = "Panel alignment", DefaultValue = HorizontalAlignment.Left)]
        public HorizontalAlignment PanelHorizontalAlignment { get; set; }

        [Parameter("Default Lots", Group = "Default trade parameters", DefaultValue = 0.01)]
        public double DefaultLots { get; set; }

        [Parameter("Default Take Profit (pips)", Group = "Default trade parameters", DefaultValue = 20)]

This is what the program looks like currently
