Pre K.O. Price

Hi
If you are referring to Match Odds market:
selection index 1 = home
selection index 2 = away 
selection index 3 = draw

say you want price of home to be greater than 2.00 at 1 min before ko:
markets betting code is match odds (soccer & tennis) or moneyline (basketball)
and selections index is equal to 1
and selections back price is greater than 2.00

you can also refer to selection index using the s_ prefix
e.g. s_3_back_price is the price of the draw
condition: selections trigger expression s_3_back_price is greater than 2.00

last_last_traded is the last traded price recorded just before the match goes in-play
