I honestly must say, during the years I have traded with CS, they cannot be accused of spiking to set off a lot of stops. CS have had other problems, but I think most traders trading with CS will agree upon, this is not something they are actively doing.lets say longs more than shorts then CS " by mistake " slowly changed the fair value to the favour of the shorts , now longs will be squeezed and stooped . And many clients dont notice this so we can say that many of them will take advantage maybe some took advantage already but not many , even u take advantage this will not hurt CS cuz if u buy others will sell they hedged u already who cares if u took few points from time to time
