And here is the result.

Well, yes it would be a good idea to optionally execute "Close Market Bet Position" bot, after dutching bet is matched.

That's great thanks   Can the market interval be changed via code?

Your bot code is executed in market update event, so if your active market refresh rate is set to 250 ms, then your bot is executed every 250 ms. For passive markets (default 10s) or markets added to bot executor tool the default settings is 1 second.

It means that when time is critical factor for your bot execution then you must set reasonable values for market update interval.

If you are using streaming for data update (that is relevant only for active and passive markets in Bet Event View and Open Markets view), then as updates are really streamed only when changes are detected, your bot can be executed in heart beat event only, set for active market to 1s and for passive markets to 15 seconds, keep that in mind!

Why is it implemented this way?

Well, because bot reacts on market data changes, and there is no reason to execute a bot when there are no market data changes.

Would you mind linking the article?  I can't find it.

Thanks

I had already answered such question.

Thanks.  Actually this explains everything :)

With the offered prices, it has probability -  could you please tell me what this is?

Please watch this video from my debugging of bot trigger code:

Debugging Bot Trigger Code

I set breakpoint, and add to watch view, selection and selection.BetPosition, so I could browse the watched object data, and see what properties are full with data.

The similar dialog I added couple month ago to bfexplorer so you can browse some market and market selection data, to learn about bfexplorer data, and how/what you can use in your bot trigger code.

Yes but this prints all the bets, with no way to get just the matched lay or matched back bets.  To get the unmatched with your code is good, but the matched doesn't work this way.  Could you please show a code sample?

Have a look at the line 34:

sprintf "%s: %A" selection.Name selection.BetPosition

selection.BetPosition object offers your bet position, so please browse data, put their break point when dubbing your bot trigger code.

The unmatched data works great thanks Stefan.  I really appreciate the code thanks. 

But I still have a problem getting the matched data.  When the orders are matched, I am trying to get the combined Odds (as float) and combined Stake (as float) for Matched Lays, and Matched Backs as shown in the Market Bets window (it combines all the Matched Lays and all the Matched Backs).  All I get with the code I posted recently is the head which is the first item shown in ther market bets window, but I can't sort the map to get the requested matched/unmatched to the head.  Could you please post the code snippet for this?  

Yes, exactly. You simply must use correct wording. “Bets” is plural, right? So it is collection, not one bet. On the object property that is bet, you could do so: bet.Price and so on.

I do not know what exactly you want to achieve as it is clear that you could have more unmatched bets on selection, so make reusable functions you could use/reuse in your bot triggers.

I wanted to explain in my sample bot trigger code, how you can work on bfexplorer domain objects, so I used direct code, but if you try to write:  unmatched .. Visual Studio will offer you all available functions/types and so available for you after you

open BeloSoft.Bfexplorer.Domain

so surprising it is offered for you:

isUnmatchedBet, unmatchedBetsExists, getBets, getUnmatchedBets, getUnmatchedBetsByBetType and so on and on.

So code I already had wrote and is reusable.

Then you could write:

let layUnmtached = market.Bets |> getUnmatchedBetsByBetType BetType.Lay

if not layUnmtached.IsEmpty

then

    let firstUnmatched = layUnmtached.Head

    firstUnmatched.Price

    ...

So do you mean something like this?:

let betSize(bet : Bet) =
  bet.Size

let getBetSize() =

 if selection.Bets |> Seq.exists (fun bet -> bet.OrderStatus <> BetOrderStatus.Matched &&   bet.BetType = BetType.Lay)
 then
 let price =  selection.Bets |> Seq.map betSize |> Seq.head

This is the correct way?  Is there not a way to do something like selection.Bets.Size or selection.Bets.Price or selection.Bets.BetType etc?

Any code, in any programming language is “sentence” expressed by programming language “words” and constructs you can make by programming, adds the language vocabulary.

So the vocabulary you can use to express your intentions in programming language is limited to couple words.

The above line of code:

let Stake = _selection.GetPriceSize(BetType.Lay)

In human sentence expresses:

 Selection, get PriceSize object for Lay side to stake!

As English have strict words order in sentence, to be grammatically correct, we command so exclamation mark at the end of sentence.

So you command selection to get PriceSize, and in this context it is Lay PriceSize offered. It is not bet, it is offer on this selection other bettors placed.

You can command bet object to get price or size to you, so odds or stake you placed a bet with.

So you must ask/command _selection.Bets to get all unmatched bets to you (to value), and then ask a bet to get you price, size and so on, like I did in my bot trigger code:

BetStatusBetCancellingBotOrchestrationBotTrigger.fsx

on the line 31.

*** 

Read further only when you want to learn some advance features of F# programming language.

***

I do not know in what context you use _selection, but please keep in mind that in F# underscore _ is used as intention to declare not used value, because in F# you must declare exact intention, so like in mathematics it does not make sense to express something what is not used.

Yes, in other programming languages, programmers used to declare object variables with _, but in F# it has different meaning, for instance here:

ShowPriceTradedVolume.fsx

On the line 52, where I declared construct for BetStatusBetCancellingBotOrchestrationBotTrigger type, I used _ for not used values, because in F# any input value/s in constructor are declared as well as object values you can access not only in constructor but in entire type.

On the line 106, you can see __ (two underscores), so in type member you must type __ to declare not used self-identifier of object. I use this as self-identifier, but you can use whatever word/character.

Ok, this underscore issue is for advance developers, you code will work whatever you will use.

***

Option value

***

For the option types/values it is similar like in C# for Nullable. So you can use anOptionValue.IsSome and if is some you can get value by: anOptionValue.Value, but better way is to use match expression or functions from Option module, like Option.iter.

In my code you can find maybe, computation expression I created, so for options you can type simplified expressions, for instance here:

ShowHorseData.fsx

Lines from 39 to 43, and then on line 40, let! ... actually evaluates if mySelection.MetaData.IsSome and continues only when it is assigning to metaData the value, otherwise returning None.

Such expression allows me to write less code. Programming is not about writing a lot of code, actually less code is always better approach.

Programming is about understanding of context in which you write the code, and so it is about interpreting of “words”.

Maybe GetPriceSize is not the code I'm looking for?  When a bet is matched or partially matched, it has the Stake that is matched and the odds it is matched at.  So the code I am looking for that you have questioned is to find the stake amount that is matched.  Thanks

Peter may I ask you to explain me by your own words, how do you understand this line of code?

let Stake = _selection.GetPriceSize(BetType.Lay)

As you may know, and now I speak not about programming languages, but about languages, my mother’s language is Slovak, and in many Slavic languages there is no such strict rule for word order like in English sentence.

That is the funny part in your question, because well my understanding of any language construct is a little bit different from the way only English people could read the code, the sentence.

Well, yes I understand what you want to try to do in your code, but the “words” you chose to do so are quite unclear for me.

Thanks for the info Stefan.  I am trying to use the info for a selection like this:

let UnmatchedLayBets () =

if _selection.Bets |> Seq.exists (fun bet -> bet.OrderStatus <> BetOrderStatus.Matched && bet.BetType = BetType.Lay)
then
let price = _selection.GetPrice(BetType.Lay)
let Stake = _selection.GetPriceSize(BetType.Lay)

if price > 10.0
then

outputMessage (sprintf "Unmatched Price > 10: %.2f " price )

But the error exists because the result is a float option.  I have tried to find how to cast the float option to float so that I can use the result in calculations but have not found how to do it yet.  How would I return the stake and price as a float so that I can use it?  I'm sure this is an easy question for you but I have been pulling my hair out over this.

this. is used to access object properties or methods.

You type your code as you would access static method or type. You must type object, so in this case maybe: market.MarketInfo.StartTime
