In the last 2 days - suddenly my mt5 will not save 0.04 as a setting , or 0.07?

Is this a bug??

 
Floating-point has infinite number of decimals, it's your not understanding floating-point and that some numbers can't be represented exactly. (like 1/10.)

Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.

If you want to see the correct number of digits, convert it to a string with the correct/wanted accuracy.
