Place new orders into market. This operation is atomic in that all orders will be placed or none will be placed. Please note that additional bet sizing rules apply to bets placed into the Italian Exchange.
By setting the optional parameter ‘TimeInForce’ on a limitOrder submission to the value ‘FILL_OR_KILL’ and optionally passing a minFillSize value, the Exchange will only match the order if at least the specified minFillSize can be matched (if passed) or the whole order matched (if not). Any order which cannot be so matched, and any remaining unmatched part of the order (if minFillSize is specified) will be immediately cancelled.
Please note: the matching algorithm for Fill or Kill orders behaves slightly differently to that for standard limit orders. Whereas the price on a limit order represents the lowest price at which any fragment should be matched, the price on a Fill or Kill order represents the lower limit of the Volume Weighted Average Price (“VWAP”) for the entire volume matched. So, for instance, a Fill or Kill order with price = 5.4 and size = 10 might be matched as £2 @ 5.5, £6 @ 5.4 and £2 @ 5.3.
We have added an additional optional parameter ‘marketVersion’ to the ‘placeOrders’ and ‘replaceOrders’ operations. The MarketBook data item, which contains the dynamic data on a market, including its prices, has always returned an integer market ‘version’. This ‘version’ is incremented when significant events – runner removal, turn in-play etc. – occur. Now, by passing that version as ‘marketVersion’ with your orders, you can specify that if the market version has been incremented beyond that value, your orders should lapse and not be submitted for matching.
This functionality should be of use to those who want to bet right up to the actual ‘off’ of a horserace or sporting event but be confident that you’re not inadvertently bet into the first seconds of in-play after the off. Similarly, in managed football markets, you can avoid your bets reaching the Exchange after the market has reformed following a goal being scored etc.
The ‘market version’ value (on listMarketBook and on ESA) is incremented for any and all changes to the market.
However, to prevent falsely blocking bets we keep track of the last material change (which we define as one performed under suspension**) and will only accept bets placed with that version or later.
Minimum version to not be rejected
Start time updated (market not suspended)
Non-material change, bets placed before change but received after will be processed normally
Runner removed (under suspension)
Material change, bets placed before change but received after will be rejected.
Market turned in-play
** this includes:
- Runner removal and addition
- Turn in-play
- Lapsing or voiding bets (eg on goals being scored in managed Football market)
But not (e.g.) updating Tennis court times or Golf tee times as they become more accurately known on the day.
Currently, best execution, which guarantees that you’ll receive the best possible price, means that you receive a greater potential payout to the same stakes (or risk a smaller potential payout to the same backer’s stakes, for layers).
If alternatively you should wish to benefit by receiving the same potential payout as you originally requested, but to smaller stakes, you can now specify on a LimitOrder (placeOrders) an optional ‘betTargetType’ of ‘PAYOUT’ or ‘BACKERS_PROFIT’ (the latter being identical to layers’ liability) and a ‘betTargetSize’ representing the value of that payout or profit, together with the usual ‘price’ parameter to represent their limit price. Your bet will then be matched to achieve that payout or profit at the specified price or better.
Should all or any of the order be unmatched after first reaching the Exchange, the unmatched portion will be expressed in standard price and backers’ stake terms (by dividing the remaining unmatched payout by the price, or unmatched profit by the price – 1, and placed on the unmatched queue), after this point the bet behaves like any other.
In order to allow customers to bet to smaller stakes on longer-priced selections, an extra property has been added to our Currency Parameters – “Min Bet Payout”.
As currently bets where the backer’s stake is at and above the ‘Min Bet Size’ for the currency concerned (£2 for GBP) are valid. In addition, bets below this value are valid if the payout of the bet would be equal to or greater than the value of ‘Min Bet Payout’ - £10 for GBP. For example, a bet of £1 @ 10, or 10p @ 100 or 1p @ 1000 are all valid as they all target a payout of £10 or more.
Please note: This function is only enabled for UK & International customers and not .it, .es, .dk jurisdictions.
Each Way betting is available via the API. Each Way markets can be identified as marketType EACH_WAY using listMarketCatalogue. The divisor that applies to the EACH_WAY market is returned by listMarketCatalogue via the MARKET_DESCRIPTION MarketProjection.
Please see table a table that indicates how the “Each-Way divisor" is determined for specific race types:
Number of Runners(1)
Number of Places
Fraction of Win Odds “Each-Way divisor"
16 or more
12 to 15
8 to 11
5 to 7
8 or more
5 to 7
(1) Number of Runners at Market creation time; place terms are fixed for the life of the market (like Betfair Place market) not dependent on number of runners at the off (like Fixed Odds EW markets)
We will not offer EW markets if the number of runners at market creation time is 4 or fewer
