most_traded_price in-play only

If i'm not mistaken, most_traded_price is overall (pre and post off)

Is there a way to make most_traded_price reset at inplay starts? So it only counts inplay information

If not, what would be the formula to custom make it?

Hi
I don't think this would be possible to do because you would need to monitor traded volume for every price tick and then sort them lowest to highest. most_traded_price data is provided directly by Betfair.
