trigger to level a trade

[dflowe]

hi If I lay a dog befor the off and then want to trade out at SP I am using LAY-PL10-SP but if the sp part comes in to play because the bet has not been matched earlier the result is not ballanced across the book, now this works in my favour quite a few times a day but when it goes against me then it results in normally a bigger loss than it would if it had been leveled......any ideas how to level an sp bet after the initial lay bet? thanks

Have a look in the manual for the trigger modifier -SPC that might be better
