(Pre-off Horse racing) How to Store Prices of one's own Matched Bets?

[lotora]

I know how to store LTP, volumes, etc within a market, but how to store the prices of one's own matched bets Pre-Off? (used for automatic trading in-play)

you'd have to store a value when you were placing the actual bet (based on current back/lay price). of course, this would get overwritten each time you backed or layed the same selection.

tbh, it wiould really depend on how you then wanted to use those stored prices as to HOW you would store and access them.
