What is Green Up (Hedging Out)?

How Greening Up Works

When you back a selection on a betting exchange and its price subsequently shortens, your original bet is showing a notional profit before the event has finished. You can lock in that profit by laying the same selection at the lower current price. Because you are now both backing and laying the same outcome, one side will always win and one will always lose — but by calculating the correct lay stake, you can arrange things so the net result is a small gain whichever way the event goes.

The arithmetic matters. Suppose you backed a horse at 6.0 (decimal) for £10, giving potential returns of £60. The horse drifts to 4.0 in the market. Your lay stake to green up fully is calculated as: (back stake × back price) ÷ lay price = (£10 × 6.0) ÷ 4.0 = £15. If the horse wins you collect £60 from the back but pay out roughly £45 liability on the lay (plus exchange commission, typically 2–5% of profit on most platforms — rates vary). If it loses, your lay wins £15 and your back stake is lost. With a correct calculation you end up with the same net figure either way. You can also green up partially, taking some profit while leaving a portion of your original position running.

A Worked Example

A tipster advises backing a football team to win at 5.0 on the exchange. You stake £20, giving a maximum return of £100. At half-time, with the team 1–0 up, the market has moved and their win price is now 2.5. You decide to green up. Using the formula: (£20 × 5.0) ÷ 2.5 = £40 lay stake. Your lay liability is £40 × (2.5 − 1) = £60. If the team wins, your back pays £80 profit and your lay costs £60, netting £20 gross before commission. If the team does not win, your lay returns £40 and your back loses £20, again netting £20 gross before commission. After a 2% commission on the winning side, you clear just under £19.60 in either scenario.

This illustrates both the appeal and the cost of greening up. You sacrifice the full upside — if the team had won without hedging, your profit would have been £80 — in exchange for certainty. Whether that trade-off is sensible depends on your assessment of the remaining probability and how much value remains in the position.

Why It Matters When Judging or Following a Tipster

Greening up creates a significant record-keeping problem when evaluating tipster performance. A tipster who advises an entry price but later trades out at a profit will show that selection as a winner — or at a minimum, a profitable trade — but a follower who was unable to access the exchange, or who was not watching the market in real time, may have simply held the original bet to settlement and either won or lost at full odds. The two outcomes can be very different, and a tipster who routinely greens up will have results that are difficult or impossible to replicate without active market monitoring.

When reviewing a tipster on TipsterCheck, look for transparency around trading activity. Does the tipster disclose when they green up? Do their published profit figures reflect the greened-up return or the settlement outcome? A service built on trading strategies is not inherently worse than a pure tips service, but it requires different skills from the follower and carries exchange commission as an ongoing cost. Comparing a trading tipster's record with a level-stakes, odds-to-settlement record is comparing two different activities, so context and clear disclosure are essential before subscribing or attributing results.
