Conditional Bets Query

[chaser]

Hi Gary / Mark
Having placed a Lay bet, I use the Conditonal Bets feature to place a Back bet as a 'stop loss'.
I select back price at <= at the odds I want the bet to be activated at and the stake I want to make.
'In-running' my back bet is triggered, but only a part of my stake is filled.
Should not the whole of my bet be taken, at different falling odds, as I have selected <=,until the whole of my stake is taken.
In the race in question,yesterday, the selection that I had layed was running well, and my conditional bet was triggered, but only to a fraction of my stake. The horse looked like winning and there was liquidity in the market at lower odds, but the rest of my stake was not placed.
Will the set-up not do what I am hoping it will do ?

<= only means trigger the bet if less than or equal to the odds specified in the "Check price" column and place it at the odds specified in the "Bet price" column. It does not guarantee to get your bet matched.

To give you more chance of getting matched you can specify an offset in the tick offset column. If you specify -10 ticks for example then it will place the bet at the odds in the bet price column less 10 ticks.
