HomeFeaturesTriggersBack and Lay Dutching on specified favourites with a target profitDescriptionThis example is an extension of the standard Auto-Dutching tool of MarketFeeder Pro. While this tool solves the majority of tasks related to Dutching, you may want to further tune it up, so a trigger will be a better solution.So in this example we choose the number of favourites we want to bet on, in the percentage of the field. For example, 50% stands for the half of the market's runners, 30% - for the first third of the market runners and so on.Then we stipulate that the minimum amount offered on each selection we'll be betting on (or against) should be no less than the value specified. This is some insurance against unmatched bets (although no guarantees).Finally we fix a target profit for the Dutching.TriggersDownload the trigger fileThere are two triggers in the file - one for Back Dutching and another for Lay Dutching. Note that the laying trigger will lay on the opposite part of the field, to generate profit on the chosen selections (this is the way Lay Dutching works). Make sure you only activate one of those triggers.Use the constants to adjust the parameters of the Dutching.If you have not heard of BetFair yet or do not have an account, register today and get £20 free.

HomeFeaturesArticlesWhat is a trigger?

HomeFeaturesArticlesMain Market Liquidity indicators in sports betting on BetFairBy liquidity we often mean the amount of money available for trading and the speed at which bets are placed and matched in the market. In MarketFeeder Pro, we have a number of liquidity indicators that will help you bet smarter on BetFair.Market VolumeThe main liquidity indicator is the amount of money matched in the market already, i.e. its volume of money. The more money is already matched, the higher is the bettors’ interest towards this market, so the more likely it is that your own bet will be matched.For example, in football, good liquidity is anything above £10,000 at the start of the match. How to check this in a trigger?Market’s Matched Volume is equal or greater than XThe trigger variable for the market volume is market_volume.Price GapAnother indicator is the difference (gap) between the back and lay prices of the selections participating in the market. In other words, back prices are too low and lay price are too high, this is a sign that the market has not attracted too many bets yet. The favourite selection (the one with the lowest price) must have no more than 5 ticks between its back and lay prices for the market to qualify as liquid. How to check this in a trigger?Selection’s Back Price is equal or greater than r_ticks(lay_price, -X)where X is the maximum number of ticks.Last Traded PriceThe last traded price is the price at which the last bet was matched on the given selection. Often once a market has been added on BetFair, it has zero liquidity and no bets are matched, so the last traded price is null. The closer the last traded price to the current best back or lay price, the more probable it is that your next bet will be matched fast. How to check this in a trigger?Selection’s Last Traded Price is greater than 1.0and Selection’s Trigger Expression ABS(g_ticks(last_traded, back_price)) is equal or less than Xwhere X is the maximum number of ticks by which the Last Traded Price can differ from the best back price.Book%A book% is a sum of a selection’s chances, where a chance is defined as 100/price.In a high-liquidity market, both back and lay book% are as close to 100% as possible (the back book% is slightly greater than and the lay book% less than 100%). The further the book% is from 100%, the less dynamic the market is.How to check this in a trigger?Market’s Back Book % is between 1 and XAnd Market’s Lay Book% is equal or greater than YThe trigger variable for these are back_book and lay_book.Amounts Offered at the Best PricesThe amounts of money offered at the best prices (back and lay) of a selection is also a liquidity indicator, albeit an indirect one. If, despite being in a close succession, the prices of the selection are not supported with enough money, your bet is likely to remain unmatched.How to check this in a trigger?Selection’s Back Amount/Lay
