    Betfair disables live betfair api access for accounts having no money on, placing no bets or breaking their T&C.

    Yes, you have got professional subscription, so it means something went wrong when authorizing your subscription status.

    Close bfexplorer and re-login again, let me know if you have got still wrong subscription status.

    Check your antivirus software. Maybe requests to my authorization server are blocked.

    It is Boolean algebra, and you can use any combination of parameters you like.

    From your example: MatchTime>45 And ScoreDifference>1

    Let’s say that the match time is 30 and score is 0 – 0, then from Boolean algebra you have got False and False what is equal to False, that means your trigger will not be fired.

    Let’s say that the match time is 46 and score is 0 – 0, the result is True and False, what equals in Boolean algebra to False, the trigger is not fired.

    Let’s say that the match time is 50 and score is 2 – 0, then from Boolean algebra you have got True and True (score difference is 2, what is > 1), this Boolean formula is equal to True, that means your trigger will be fired.

    When you combine with And operator then all partial results must be True, to give you full results as True.

    Using Or operator gives you True result when at least one partial result is True.

    You can replace True to 1, and False to 0, then And Boolean operator is in algebra like * (multiplication), so 1 * 0 = 0 (False), 1 * 1 = 1 (True), 0 * 0 = 0 (False)

    Croatia beat Argentina 3 – 0 at World Cup in Russia.

    What were My Tipsters selections for this match?

    My tipsters selections

    16 tipsters selected Argentina, 5 tipsters Croatia, and 5 ones the Draw.

    If you filtered Tipsters by ranking <= 10, and by positive “All Time Roi” you would get 3 tipsters from which two selected Croatia as winner selection.

    My tipsters - Ranking <= 10

    Public voted 55.12% for Argentina and 27.31% for Croatia win.

    Click to input text box, for StartCriteria or StopCriteria, in the right side of the input box appears button […], click on it and Criteria Editor appears, enter your criteria and click on OK button.

    Now you can see that Criteria Editor created text representation of your formula, so if you can type criteria formula by text input then you can do so with exact format Criteria Editor uses.

    You can change view layouts, resize, dock, or undocked views, close/hide unused ones and then add your workspace by clicking on the menu item View / Workspaces / Add.

    This way you can create many workspaces for different use scenarios, I have got such two workspaces the one for bot execution, and the one for manual traded, so Bet Event view is switched to ladders. I have got special workspaces created for tennis treading or horse racing trading when utilizing market data on one ladder. Please have a look on this articles and videos.

    Monitored column (including the column: “Total Matched”) fully describes monitoring status. I do not like to overcomplicate user interface (UI) with a lot of displayed data, less data displayed in UI means more clear UI.

    I was thinking to change “Football Bot” parameters similar to mentioned "If Then Else" bot, adding Score, MatchTime and GoalDifference parameters, then you would be able to set criteria for Start and Stop criteria, combining a lot of criteria values.

    Have a look at on mentioned bot and let me know if you will manage setup such bot, as Criteria Editor could be too complicated for some users with a common sense in Boolean algebra.

    English is foreign language for me, so maybe I have got bad felling in using some words, but in this context “Monitored” term says: has been monitored, and as well is monitored.

    I wanted to show flag, so you can filter, group or sort markets in “Bot Executor” view by Monitored column and so differentiate among those three states: is not yet monitored, is monitored, has/had been monitored.

    Grid view offers other three columns which are by default hidden, but you can show them by clicking on column with your context mouse button/right mouse button, then clicking on Show Column Chooser, from which you can drag and drop hidden column to the grid view. I suggest to show (drag and drop) “Total Matched” column, so you will see that what I was talking about really works.

    If market is monitored by “Bot Executor” tool then “Total Matched” changes values when data are reloaded from betfair servers.

    If you run your bots in Bot Executor tool, then Bot Executor stops market monitoring immediately after no bot is running on the market.

    “Football bot” offers the parameter:  MatchTimeStop, so when the parameter is set, the bot stops its execution after set match time is reached (MatchTimeStop). So you can simply set MatchTimeStop to more than 75.

    Score parameter allows multiple score entries (separate them by ;), for instance: 0 – 0;1 – 1

    Alternatively I can reprogram “Football bot” to implement criteria similar to bot:  "If Then Else"

    You can see PriceTrend value on each ladder, under selection name. It is calculated from local minimal or maximal reach price (odds) and the current price.

    Book value is 100% and higher, for back prices and under 100% for lay prices.

    OfferedAmountToBack/ToLay is calculated from 3 best offered prices.

    Let’s say you have got a strategy running on football markets, you execute it on match odds market because decision to trigger bots is done by match time and/or score.

    You setup your action bots, and then two bots to be open on associated markets using the bot: "Execute On Associated Market", on Under/Over 1.5 and Under/Over 2.5, so you will setup: one bot setting with MarketName: OVER_UNDER_15, and the other one with OVER_UNDER_25.

    So you have got two bots to be executed when your trigger criteria are met on “Football Bot”, but as you already noticed “Football Bot” takes only one bot name in the parameter: BotName.

    Open “Add a new bot” dialog, and type Execute in Search box, what bots are listed? Six bots starting with Execute .., what do you think the bot: “Execute Bots” could do?

    Well, yes exactly what the name of bot says, it will execute bots, defined by parameter: BotNames, so you can add there your two bots to execute your strategy on Under/Over 1.5 and Under/Over 2.5 markets, and you name such new bot, “My football action bots”.

    Now you have got one bot, which can be added to “Football Bot” parameter BotName, and when triggered it will open two associated markets, and execute your action bots on them.

    I would really suggest you to read bot names and description of bot parameters this is all what you need to understand.

    Bot setting is your instruction to be executed, that is all, similar like in programming code where lines of code express instructions of code execution.

    Bots like “Football Bot” or “Execute On Associated Market” just execute action bot set by parameter BotName, nothing more!

    If your bot places “tons of bets” as you say, then you should check bot settings of bot/s which place bets.

    What you could make wrong is as well to add in sequence of your bots execution the same bot, which takes execution in recursion, therefore I asked you to make short video showing your bots settings (just sample if you think someone would steal your strategy this way), and how you use it.

    You did not make such video so it means you have basically problems to use any software, right?

    Well, I cannot help you anymore to understand how any windows software is used. It is really only up to you, learn and if not understand just try again.

    In bfexplorer when you construct your bot strategy by setting more bots, you should check each bot settings in practice mode and see what bot does when executing, that is the only way how to check if all works fine.

    If you have no software for making screen recording, then please install ShareX:

    Make a short video showing how you set you bot and post it on youtube, so I can see what you actually do when setting up your bots.

    You must setup one “Execute On Associated Market” bot per each MarketName, if this bot would supported execution of BotName on many associated markets then parameter name would be plural MarketNames, and not singular: MarketName,  do not you think so?

    You can execute more bots by bot named: “Execute Bots”, where in the parameter: BotNames, you can see plural, so suggesting that you can enter more than one bot.

    What do you mean “by your bots”? Did I make you some custom built bot? If yes, then I should have rebuild bot assembly, contact me by email. If not then just recreate your bot settings, it could happen that version of bot settings data serialization changes, so it fails loading old version of data.

    I added "Execute At Time" bot.

  • Stefan
    25.3.2018 16:46:42

    "Cancel Bots On Selection" bot stops its execution immediately, so adding "Stop At Time" does not make a sense. In your case you trigger this bot using “Football bot”, so what is actually important is time of execution.

    Have a look at “Fill or Kill” bot parameter named: Odds. Read what description for this parameter says: “The odds you want to place your bet at. Set to 0 if you want to offer your bet at best offered odds.”

    What does it mean?

    Bot either places a bet at required odds, or offers bet. If there is no offer on back side and you asked to place Lay bet, then bot will waits till some offer appears because bot does not know at what odds you want to place a bet.

    Just to test bot functionality set your bot to place lay bet at 1.01 odds, and you will see that all works fine.

    Of course I tested it.

    You can open two instances of bfexplorer and do the same what you do with geeks toy.

    Actually if you open the market in bfexplorer and market is active then you will see bets even in one running instance of bfexplorer, because active market is updated immediately after you switch it to be active one.

    On markets with small liquidity and on markets where market data are not updated so frequently your bot can be executed with very big update time interval when market is in passive mode, because market data are updated really only when there some changes, this is the behavior of streaming api technology.

    If you switch to normal mode, then passive mode updates, and so bots execution is really executed each time set by update time interval for passive markets.

    Switch bfexplorer to streaming api, open market and watch for changes, on markets with small liquidity you can simply see that market shows no changes for minutes!

    So if you operate on markets with small liquidity then use normal mode, not streaming, but then you are limited to number of open markets you can monitor simultaneously.

    I hope you are able to use your common sense in this case.

    Please make short video showing your problems, because what you say make no sense for me.

    When bet/s is/are placed on betfair market, the same way like market data are updated, bets are updated as well, I mean loaded to app model.

    So if you see bets on ladder, they are correctly loaded to market data, My Bets view is just other visual representation of your bets, like on ladders is another visual representation of the same market bets.

    The “Fill or Kill” bot works fine, and it does not matter by which trigger bot it was executed.

    I already mentioned how a bot is executed on betfair markets, but it seems you do not understand it. Bot is a program/code but its execution time is limited to time when market data are updated only.

    Bfexplorer offers two types of market data updating, using streaming technology or simply calling api method for updated market/s at preset time interval, keep in mind that there are two update intervals, for active and for passive markets.

    When using streaming api to update market data, the data are really updated only when changes are detected on betfair servers, so it means even if you set your update interval for passive market to 10 seconds, you will not get updated data if no updates are made in 10 seconds interval on betfair servers.

    In such cases, betfair streaming api offers “heartbeat” so each 60 seconds there is triggered update procedure, so chance to execute a bot as well, but I implemented it only for monitoring active market, for passive markets bot is really executed only when there are detected changes on the market/s.
