Hi all,
 
	I am also a user of TWS mainly because I use Linux and also paying an extra platform . Nice info in this thread.
 
	I have the same issues pointed out here: making horizontal lines takes too long...has anyone written to IB support asking for some support on it?
 
	Other question: how do you put the executed trades mark on the chart as triangles? I have only little bars...
 
	Concerning the closing and partial closing of the open orders I have done it by using the reverse order thanks to the tip of Will S and in my version there is the action for the hotkey close position, but I still have to test it.
 
	 
 
	Looking forward to your reply.
