Custom basket trading interface VBA/Excel 2013 to IB TWS API

Currently placing market orders through IB TWS BasketTrader with separate csv files for 6 segregated client accounts. Need to integrate the task to one Excel interface/worksheet. Column A contains the list of desired symbols separated by short and long. All intraday market orders with specific entry/exit times per account. US regular trading hours only 0930-1600 EST. The intention is to toggle/click AUTO ALL before market open and have positions automatically scheduled to open at desired Entry Time(s) and closed at desired Exit Time(s). Toggle meaning like click to turn on, and click to turn off, like a button. The individual AUTO Cells should all turn on when AUTO ALL is toggled on, but also allow for turning on/off individually if desired. Also, CLOSE ALL will not function as an on/off toggle, but as a button that should instantly execute the closing of all positions in all accounts by manually clicking it. The individual CLOSE buttons will function the same way, but instantly execute the closing of all positions in selected client account/column. Ideally that would happen with the AUTO/AUTO ALL buttons in off positions to avoid conflict. Upon, opening file, VBA/Excel needs to establish auto-login to all the client accounts. Also need Excel/VBA to send an email alert from my Comcast SMTP email account/login, to two other email addresses if any cell values in Open Positions (cell N15:S15) change between 0930-1600 EST, regardless of client account. I don't want to use MS Outlook. The attached image is my prototype. Recommended improvements are appreciated.
