    1) You must run Visual Studio as Administrator

    2) Debug your project starting external program:

    C:\Program Files (x86)\BeloSoft\Bfexplorer\Bfexplorer.exe

    3) And of course the project must be built to:

    C:\Program Files (x86)\BeloSoft\Bfexplorer\

    So you must set Build/Output path

    It is possible to write simple bot trigger script, as an example look at here:

    Lay the favourite <50% market

    It shows how to use traded volume. I will make your trigger later today.

    To Bot Strategy:

    You can use Place Bet bot as the main bot placing your bet, first setting it to place bet at exact odds, then setting it to take what is offered, or end the bot execution. If bot execution is ended/cancelled then all unmatched bets placed by the bot are cancelled.

    It means that you have to program just bot trigger changing the bot settings at required time.

    To Bfexplorer BOT SDK:

    The error message is clear. You must build your projects to .net 4.7.2 because bfexplorer app is built to this .net framework. 

    The summary:

    Well, if you were not able to fix your problem when building Bfexplorer BOT SDK projects yourself, I do not think you will be able to program your bot trigger strategy.

    Therefore use just Place Bet bot to place your bet at allowed odds range, so no needs to program anything just setting up the bot and run it.

    I have developed my web site as well, so here you can search the web site, typing your search term in the “Search in site”.

    If exact term is not found, web site offers context search trough bing or google.

    Bfexplorer BOT SDK (Visual Studio solution) contains 14 projects. To start all you need is to open this Bfexplorer BOT SDK.sln solution in Visual Studio.

    If you set the Bfexplorer BOT SDK main project to be: JayBeeBot, then you can start debugging the WinForm app that uses BfexplorerService in very simple UI app. So running this app the simple UI appears and in menu you can login, clicking on Application / Login.

    By the way bfexplorer app uses the same BfexplorerService to implement all features you can run in bfexplorer app. What does it mean? You do not have to program what I already programmed in bfexplorer app, because BfexplorerService offers base features you need.

    The rest of projects use different approaches, showing how to use Bfexplorer BOT SDK to program bfexplorer bots, tools, plugins, bot trigger script codes, or console scripts.

    When debugging such projects you enter your betfair credentials through Debug / Command line arguments in Visual Studio.

    I have written about it in many forum post or articles.

    I do not know what you want to implement, but I offer my services to develop betfair bots which are integrated in bfexplorer or bespoke apps.

    Just google the term: IntelliSense

    IntelliSense is a general term for a variety of code editing features including: code completion, parameter info, quick info, and member lists. IntelliSense features are sometimes called by other names such as "code completion", "content assist", and "code hinting."

    All my projects in Bfexplorer BOT SDK are either C# or F# projects, and are run-able by bfexplorer app or as standalone apps.

    C# and F# in Visual Studio, and for all the rest of programming languages, support IntelliSense so you actually do not need documentation.

    Yes, for now you do not understand what advantage of using Bfexplorer BOT SDK you can get when programming tradinging strategies. I read the same forum as you do for python wrapper library of betfair api, so it will be interesting for me to follow your progress there.

    Please read about Bfexplorer Bot SDK and Bfexplorer Console. Actually there is quite a lot of options you can use to do the same I had done on the video. 

    Bfexplorer Console offers scripting language, in this case F#, to access any market data bfexplorer app opens.

    To develop tools or bots you can use any .net programming language and integrate your code, better to say assembly with bfexplorer app interface.

    Your subscription code was correctly activated by betfair, and your subscription is valid till 8th Mrach 2021. 

    You can check your subscription status using My Subscription Details.

    Sir, do you understand that activation is done on betfair server not on mine one? In some cases it takes some time on betfair side, so your error message you recevied from betfair when activating subscription code describe the problem which occured on betfair side.

    Bfexplorer app loads any data through betfair API, so when betfair changes its naming convention for racecourses, bfexplorer loads that data. For horse racing markets you can find this data in MarketInfo.BetEvent.Details (Open from the market context menu: Show Market data).

    When I develop custom bots for my users I programmed bots with entry parameters, it means that you must change values for such parameter in your bot settings only.

    Of course if your bot is programmed by using exact text for racecourse name then you must change it in your bot code.

    What video do you mean, becuase the problem with embeded internet browser in apps is a little bit difficult? IE which is defauflt UI control for browsing Internet content in apps does not support streaming the betfair video stream is using.

    What I showed in one bespke app was using Edge UI control, still in beta version at the moment when I tested that.

    The link for Betfair Live Video:

    You can add it to your Web Browser view in bfexplorer app.

    Bfexplorer does not force delayed data usage, but betfair does, it is betfair api data and service. Is it not clear for you?

    Please sir, read betfair T&C:

    Just common sense: You have got nothing for free in the World. Betfair business plan is taking fees on winning bets up to 5% depending on from which country you are and on what markets you bet/trade on.

    If you do not bet, you do not generate fees, so profit for betfair. If you keep taking data through betfair api without betting, betfair will first turn your account api access to delayed api data, and later close your betfair account.


    At the moment you are trialing bfexplorer app for free. When your trial expires you can subscribe:

    Yes, I offered free community access before. My idea was to get free access to users popularizing my bfexplorer app, so posting on forum relevant information, helping this way other users. Unfortunately this never happened, and you can actually check on the forum why.

    If you are software developer yourself then I would give you free access when posting articles about bot strategy development. Yes, bfexplorer app is open platform for bot development:

    I have attached video from my test today. Football live score and football bot work without any problems. So there is question what is wrong with your computer?

    You already created strategy bot, so all you need is to copy/clone it, and name it differently. I already said that bot executor creates execution loop by unique bot name.

    You can add as many of favourite’s events as you want to, so create one for horse racing and the other for greyhound racing.

    You have got your bot strategy created, and so the tool “Strategy / Bot Executor” can be used on both events, just start your strategy first on horse racing markets and then on greyhound racing markets.

    As the “Strategy / Bot Executor” creates execution loop by strategy name you can run this way your strategy on whatever markets you want to.

    On the other hand in such case you cannot execute your strategy in fully automatic mode, so reloading markets each day automatically, because “Strategy / Bot Executor” needs to know which favourite event to reload.

    Yes, your strategy can be automated by console script, just search forum for such solutions.
