Profit Loss in running

[laymore]

Is there a way to find out profits for in running trading, Betfair profit loss doesn't offer anything to filter results based on when the bet was placed.
i reckon i do badly on the in-running compared to the pre race trading but some precise stats would be great, someone has an excel spreadsheet for that or an advice how to find that out please?
I don't need advice like stop in-running trading until i know my results...
thank you

Not unless you download your P/L to excel and filter the bet placement times, although you would then need to know the off time if the race started after post.
