Executing Arbs
Receiving an alert is just the beginning. Profitable arbing depends on fast, precise execution across two bookmakers simultaneously. This guide covers every step from alert to confirmation.
Step-by-Step: Executing a Standard Arb
Receive the alert — read the full breakdown
Note both bookmakers, the odds, and the pre-calculated stakes. The bot shows you exactly how much to place on each side.
Open both bookmakers simultaneously
Use two browser tabs, two devices, or their mobile apps. The faster you move, the less chance of odds changing.
Check current odds match the alert
If odds have moved, press 'Edit Odds' on the alert. The bot recalculates margins and stakes instantly. If it's no longer an arb, don't place.
Place the smaller stake first
Start with the bookmaker requiring the smaller stake. Less capital is at risk during the gap between placing both bets.
Place the second bet within seconds
Confirm both bets are accepted, screenshot your bet slips, and record in /track. Most arbs close within 60–120 seconds of appearing.
Reading the Alert Buttons
✏️ Edit (Home/Away Stake)Modify one side's stake — the other side auto-recalculates to maintain the arb.
💰 Edit Total StakeChange the total amount across both sides and the bot re-splits automatically.
📚 Edit (Home/Away Odds)If odds have moved, enter the new price. Bot recalculates the margin and tells you if it's still an arb.
Standard / RF High / RF LowSwitch stake strategy. RF High = big profit on underdog. RF Low = steady profit on favourite.
Common Mistakes to Avoid
❌ Placing one side and assuming the other is still available
✅ Always verify the second book's odds haven't moved before placing the first bet.
❌ Forgetting exchange commission (LAY arbs)
✅ Set your commission in /settings → Exchange Commissions. The bot won't apply it otherwise.
❌ Using the stake calculator number exactly (looks like arbing)
✅ Round to nearest £5 or £10 to look less mechanical to bookmakers.
❌ Taking sub-1% margin arbs during busy periods
✅ These are rarely worth the effort. Set minimum margin to 1.5%+ in /settings.
Custom Arb — For Boosted Odds
If you spot a bookmaker boost or price error not in the automated feed, use /custom to calculate your own arb.
- Bot asks for Bet #1 odds → enter the boosted/back price
- Bot asks for Bet #2 odds → enter the lay/opposing price
- Bot asks for total stake → enter your amount
- Bot outputs stakes for each side + guaranteed profit
