Greening Up ?

What is it ?

[GaryRussell]

Greening up is when you back and lay a selection with the correct stakes to guarantee the same profit whichever the result.

eg.
You have backed a horse for £50 at 5.0 for a potential profit of £200
The odds drop to 4.0 so you can now green up by laying the horse. To calculate the stake divide 5.0 by 4.0 and multiply by the original stake = £62.50, liability = £187.50.
You now have a guaranteed profit of £12.50 whatever the result.

This is what I call arbitrage, or "arbing". But where does the colour green show? Is that just on BF, or is there some indication in BA? Is this where the tree structure comes in? (I've never got to grips with that...)

The aim of greening up is to have a green number at every selection (Betfair shows them below the selection name, BA shows them in the column 'profit'). This means that you have a profit regardless of the outcome of the event.

The tree structure is just for selecting markets.

Ah, thanks.
