Hello Oxa, in answer to your questions:
1. "Do you mean the trigger should lay on the 1st favourite to generate a zero P/L on the rest of the selections?"
Yes.
---------------------------------------------------------------------------------------------------------------------
2. "Do you already have a back bet on the favourite, and you want to place two more bets on it, a back and a lay bet? Will the profit from this trade have to cover the liability on the selections that were not included in the Dutching? If yes, then you need to specify either the size of the first bet in the trade or the number of ticks that the trade must aim at, i.e. trade out at 25 ticks."
No, There is no back bet on the fave to begin with. I would like to manually place bets on another 2 or 3 horses (not the first fave/ranked), the only bet on the 1st fave/ranked would be made by the trigger bet to generate zero profit/loss and cover the liability of the other bets if it goes on to win.
For example I bet on faves 3, 4 and 5, the trigger see's I have placed those bets and calculates my liability, it then places a trade on the first fave that would generate a zero profit and zero loss situation should it win.

3. "Please specify what are the exact conditions for placing a back or a lay bet based on WOM and the volume."
I was thinking if the 1st fave runs well at the start and the Volume of matched bets continue to support its run then the trigger places a back bet on the horse and then places a lay bet lower for a cost that covers the total liabilty of the bets I placed manually at the start of the race.

I hope it makes a bit more sense, I'm quite new to this and still have a lot to learn.
Thanks again,
Simon.
