help for Green Up modification

hi,
I would like help if possible to write a green up
formula to green up to break even on other bets
rather than equal profits.
eg:
                 Back        P/L
Fav   1.8    50.00    40.00
2Fav 2.4                 -50.00
odds change:
                 Lay
Fav   1.6    50.00     -30.00     
2Fav 2.2                    50.00
the net result win 10 on fav and break even on 2Fav
Thanks if can assist.

Hi
The simple method (as your example):
Trigger 1, Back fav, 50.00
Trigger 2, Lay fav, 50.00 (or bm_backa), selection's lay price is equal or less than r_ticks(bm_backp,-20)

or have you seen this trigger http://marketfeeder.co.uk/solutions/green-up-hedge/greenup-unequal-profit/ allows more adjustment.

Manual Green up: Where you Back first.

bm_backp/back_price*bm_backa
So in your case
1.8/1.6*80=56.25

1st wager Back Fav $50 at 1.8
2nd wager Lay Fav $56.25 at 1.6

Fav Wins +40 - 33.75 = +6.25
Fav Loses -50 +56.65 = +6.25

The formula is slightly different if you lay first.

 

Thanks guys, I will work on these suggestions.
