Trading Volume Should Be Single-Counted
- By: Jim Ross
- File Under: MatchPoint
To single-count or to double-count trade volume, that is the question! Whether 'tis nobler in the mind to suffer the slings and arrows of outrageous double counting, or to take arms against a sea of over-inflaters. And by opposing, end them? Ah, Shakespeare! You clearly were ahead of your time!
Though double-counting (counting shares from both sides of a trade) are useful for marketing purposes and revenue calculations, it has no place in the standard of trade reporting for dark pool (or any pool) share volume. The "tape," which is the trade-reporting standard, reflects single-counted share volume (counting only the traded shares from one side of the trade).
Our markets may support alternative models but they should not support alternative trade-reporting standards. Single-counting is the only answer to this question!
