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 been 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.

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.
Ability to place lower minimum stakes at larger prices

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.
