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.

As James says.... But knowing the side is tricky too as you'd need to see if the price was best back or best lay when its traded vol changed. At best you'll get a rough approximation and at worst it'll be misleading. It's a limitation of the API not BA. Might be more effective to look at some sort of price momentum over a couple of different deltas.
