Grid Robot with Trailing Stop

Can Someone help me to change this things in this code?

1º Open orders always with the selected volume (not duplicated)
2º Remove the TP from the grid (just a option to adjust the distance to open new orders)
3º Add a Trailing Stop equal to grid adjustable distance


Thank you!!!
