A bit of sugar to represent a dictionary in object form where keys are set as attributes on the object. Features: it tokenizes your keys if they are not python safe ("this-key"is.this_key). Example: d=Dict({"this key":"value"})d["this-key"]# "value"d.this_key# "value" ...
Every time you receive a "size level", simply divide it by the instrument's size_multiplier value to get the size.Why aren't these levels and not prices / sizes directly? Floating point numbers in binary computers cannot represent all decimal values precisely, so we want to avoid them unti...
