Panel to close open trades if one of the selected trades been closed

Hello all,

I want a panel with two sections "main trade" and "sup trades" details below....

The main trade section has blank/input with drop down menu, to select one of the open trades as a main trade, it has also a button to remove the selected trade.

The follow trades sections has 10 - 12 blanks/inputs, each has drop down menu to choose from open trades, and button to remove selected trade. The followers trades will closed automatically whenever the main trade is closed "could be by hitting sl, tp, or manual".

All the selection process needs to be by the ticket number of those trades.

I want to add the script/EA to a chart to see the panel and select the main trades and the sub-trades. The script/EA might be added to one terminal more than once "to different charts".
