    When to use it

    The exchange only had part of your lay at the price you wanted, or you're splitting the lay between exchanges.

    Commission per lay

    Each exchange takes its own cut, so set the commission on every lay. Betfair is usually 2–5%, Smarkets 2%.

    Rounded stakes

    Stakes are rounded to the penny you can actually place, and every figure is worked out from those real stakes.

    Matched betting hedges both outcomes, but odds can move and mistakes can still cost money. 18+. Free help at BeGambleAware.org.
