Modify my EA MT4

I would like to modify my EA. It was built 7 months ago by a programmer that somehow is not available at the moment, no contact with him.

It is a London Breakout system that places pending orders few pips above the highest high and lowest low with MM TP SL BE 2 lots split.

It is already in the code.

What I need is to add  few MORE options in 24 hours cycle like pending orders in both directions at the same time and more …

Also to have the option to change colors of the box which indicates the X hours before London open and ...

To have the option to draw the boxes and not to draw.

To have an options to trade on Friday or not , and to trade on Monday or not .

To have an option :

Option 1 - only one direction open position  (if breakout is on LONG only BUY position open )

Option 2 - both positions open at the same time in opposite directions. (if breakout is on LONG - BUY and SELL positions  open simultaneously.

More specific information with pictures for the approved programmer only.

Thank you
