On a fully automated trading platform, surely a price discrepancy of $1 from the first trading screen to the second is as bad as a discrepancy of $10?
Apparently not everyone thinks so. Have not had such an ad hominem laden "discussion" since the early days of university. Particularly awkward since the character who flew off the handle at me is one of the seniors in the project and has a history working at some of the biggest banks where, from what I understand, it's pretty important for numbers to match up.
