Well I can't say for certain that all the "manual" filler are infact manual. They certainly don't input data and do a calc lol. All they need to do is wait 10 secs, see what their quote is and accept or reject. In the case of Choice they appear to be checking for arbs with other firm as they reject even though their quote does not changes, only to change their quote 60 secs later. The other reason why I am sure (but not certain) about the manual process is that quite a few firms have told me

We are all hypothesising and I maintain that the delay is a function of some automated process, if we do assume for the purpose of the discussion that it legitimately exists. Moreover, how do we know that the other vendors listed all do the same? This is not public information and it would be very expensive to manually validate binary derivative instruments. Far cheaper to hold them in the system, await further data for model input validation and then confirm the trade. Manual just doesn't make cost efficient sense in this instance.
Please note that I am not defending (or attacking) the practices of these people. Rather I am saying that manual fills make no economic sense in this context. It is not the same as spread betting where the 'price' is observable in the market and the question is one of liquidity and spread. The latter instance lends itself far better to manual interjection.
To manually validate individual bets one would require a large number of people inputting 3 to 6 variables into a model. This is illogical when a program can do it just as easily. The more I consider the matter the more probable I consider it that they are awaiting validation of their spot price input by sitting on the order until more ticks arrive.
If you have evidence that this proposition is missing an important premise then please submit it so we can throw it into the mix.
