In order to control the risk (or when the SL is too high) is it possible to change the lot size values for different currencies. thanks for the help in advance.
Yep, lot size = volume, just choose a figure from the drop down menu
or type in a figure for yourself.
Always remember to check this figure though because once changed it
will stay that way until you change it back.
Go to
Tools -> Options -> Trade
to change your default lot size to anything you want.
It has a selection list or you can custom type it in to the 1/100th of precision. I don’t know if all brokers allow this but mine does (IBFX).
Thank you Mytwopips & daydreamer. it worked like a charm. I was beating my head all afternoon yesterday to figure it out. Little help from Experienced traders go a long way… 
lot size = volume…finally my doubt cleared. tq
