Hi,
if would be very usefull for me, to have 4 additional selection variables:
bm_layliability Liability from all matched lay bets of selection.
bm_backprofit Profit from all matched back bets of selection.
You can find the figures when you select "Average Odds" on befair webpage.
(See attached picture)
And:
bu_layliability potential liability from all unmatched lay bets of selection.
bu_backprofit potential profit from all unmatched back bets of selection.
The idea of a new trigger is to enter unmatched lay bets with fixed liability in outright and cycling markets and every time a lay bet get matched I will enter additional lay bets on all other selections to keep the overall market liability constant.
