The Minimum and Maximum Order Size functions will define the minimum or maximum lot size to copy per order. NOT for accumulated positions. Please note that they don't work like a filter that will dictate whether an order should be processed or not. They will simply adjust the order size based on the min or max value you entered while respecting your broker's minimum and maximum size requirements.

What happens if the Minimum Order Size entered is greater than your broker's minimum order requirement:
If your broker's minimum order size is greater than the value entered in the Minimum Order Size field, the Trade Copier will reduce the order size to the minimum value allowed by your broker.  If you do not want to round up, disable the Minimum Round-Up feature to ignore the order. Learn more about Minimum Round-Up function. 

What happens if the Maximum Order Size is smaller than your broker's minimum order requirement:
If the minimum order size allowed by your broker is bigger than this Maximum Order Size, the Trade Copier copies the minimum order size. In this particular case, the system always tries to copy the trade with the minimum allowed value.
