Yet another issue with MT5, this time to DOM

 

How do I change the default from "2" units vol to "0"? Every time I open it the dom always has 2 units as default. Those of you that know how mt5 works if you click on an different chart the Dom changes to that utensil automatically. So if I change the vol to 1, then forget and change to a different chart/utensil and execute the trade it'll execute the default amount without realizing it.

Mt5 is just bad...Anyone know how to adjust to default to zero? Thanks
