Measure number of back bets in market possible?

[tryingtotrade]

I’m hoping to measure how many separate back bets have been placed in the market on a certain runner in a timeframe.
Say in the last 10 seconds one runner had 25 separate back bets placed on it would there be a way to measure that and store it in a value?
I would think especially in running and if you could compare it to what is being matched on the lay side that would be a stronger indicator than just price movement? Would it be possible to get the value? How would you go about it? Thank you

As far as I know the closest you can get to this is the number of times volume traded increases. But I don't think it's possible to differentiate between 1x bet at £10 and 2x bets at £5 being traded between refreshes.
