MT4 lots

what do they mean

starts at 0.01 and goes to 0.05, then 1 up to 8

why no 0.06-0.09 or 0.1-0.9

You are dealing with micro lots here.
You can enter whatever you like. If you want to place 0.04 lots then just change the number. If you want to enter 10 micros then you enter 0.10 - if you want 15 micros then it's 0.15.

120 micros would be 1.20 - which is the equivalent of 1.2 mini lots.

thanks .. i was not aware i can enter them manually
