Monitoring Bets by BetID‏

Posted in Betfair bot for this week, algorithm and strategy by Mir.

Ahoj Štefane,
 
díky příkladům vím, jak zjistit uzavřené či neuzavřené sázky.
Jak se dají, prosim tě, nejlépe zkontrolovat sázky podle BetID;  jestli jsou uzavřené či neuzavřené?

(umístím konkrétní sázku a pak chci vědět, jestli se ta konkrétní sázka uzavřela; bez ohledu na další vývoj na trhu)

--------------------------
hi Stefan and all "casual coders" ;)
For my long trading strategy I would like to know how monitoring bets by BetID. Idea is simple: I want to know if single bet placed on selection was matched or not (without other event in the market).

    Betfair bot: Bfexplorer.Scripting.TestMonitoringBetsByBetIdBot

    This simple bot script code shows how the bot places 3 lay bets. The first lay at the best offered odds and two bets offering on best back odds - 1 and 2 ticks. That means that at least two bets should be unmatched. The bot stores then the bet id of the first unmatched bet and reports all bets status. Run the bot in the practice mode to see how bots operates.

    You can manually update or cancel bet/s again to see how the bot will interact, so you will be able to understand the bot code. The bot stops its execution after all bets are placed, or when there is no unmatched bet, after cancelling them.

    class TestMonitoringBetsByBetIdBot : Bot
{
  // Const
  private const double Stake = 2;

  // Data
  private long myBetId = 0;

  public TestMonitoringBetsByBetIdBot(IBetfairService betfairService, 
        MonitoredMarket monitoredMarket, Runner runner)
