Placing opposite bet in One click

[payuppal]

I want to place an exactly opposite bet using One Click.

So if I place a back bet at 2.0 for £100, I want to place a lay bet of £100 at 2.0 as soon as the back bet is accepted.

Is this possible, and if so, how do I do it?

Thank you.

Use 'fill or kill with offset'

Set the offset value to, say one, and set the fill or kill value to a few seconds. When the first bet is matched the second will fire in automatically.
