in saying mm's wont execute unless attempted buys hit the ask

i knew when i wrote that that would give an opening by bashers to discredit so to cut them off at the pass i make a general note that all exceptions and manipulations cannot be covered in each post or such would be pages long

e.g., all or none trades=which can be seen only inhouse sometimes go below reported ask but not below in house ask- and various manipulations go below reported ask
