Single Trackers open up at their Default size of 560 X 460 pixels.

On a 1280 X 800 screen that looks like this:



So there's plenty of space to be tracking several races simultaneously, or the same event in different modes.



At 100% scale, Single Trackers look like this:



Single and Event Trackers now show 'Full Market Depth' i.e. the amount of money waiting to be matched at all prices, rather than just the best 3 prices.

You can resize Trackers by dragging, just like any other desktop window:



or display as full-screen:




On opening, the main features of a Single Tracker are: ( click on the legends to get more details)



That looks like quite a lot, and that's before clicking on the Greening / Hedging Tab, but their use is mainly self-evident, and, we hope, logical.

So, clockwise, from the top down:

• Click to Back(1) - Assuming that OneClick Betting has been Enabled for this Tracker this replicates the 'Traditional' Betfair betting Interface, except that it takes only OneClick to place a Back bet, at the odds shown on the Button, for the Stake shown in the Stake Drop Down.
  If you want to place a bet at Back odds greater than currently available, you can set those odds in the Min Back Odds box, or, you can use the +/- Ticks drop down to set the number of 'Ticks' (odds increments) above the current Best Back odds. that your offer will be made at.
  
  Setting Minimum Back Odds / Maximum Lay Odds or +/- Ticks is also a useful safeguard against accidentally backing at much Lower odds or Laying at much Higher odds than you intended when prices change dramatically just as you are clicking the Back or Lay button.
  
  But probably the best way to choose your odds, and to avoid 'Trap Bets' is via our new Ladder Interface.
  
• Click to Lay(1) Same, in principle, as Click to Back(1) .
  
  Remember however, that (in line with the Betfair website) when Laying, the Stake (as shown in the Stake DropDown) is your potential profit if the Selection loses its event, and that your Liability, if it wins, is the Stake * (Lay Odds - 1).
  In other words, a £100 stake at 5.0 has a potential liability of £400.
  
• Betfair Graph - Clicking on the Graph Button will open a small window with Betfair's Price/Volume over Time Graph for the current Selection:
  
  
  
  
  
• Bet Display Refresh Rate - changing this rate will temporarily override your Default Bet Display Refresh Rate.
  
  If you have a lot of Bets on the current selection, there can be some screen flicker as the Display refreshes, so you may wish to set this rate higher, e.g. to 5 seconds.
  
  However, if you are waiting to see whether a current unMatched Bet is being matched, then you may wish to set the Refresh Rate to its minimum - 1 second.
  
• Volume Button - Clicking on the Volume button will superimpose a graph of the Percentage of Total Market Volume matched over Time for the current Selectione:
  
  

  Market Volume is the total amount of money currently matched in the selected market (as defined by Betfair), and the Volume % is the total amount matched on the current Selection expressed as a percentage of the Market Volume. Please note that there is no relationship between the scale or timescale of the Last Matched Price and % Volume graphs. The purpose of the % Volume graph is simply to indicate the direction of movement of the Volume % for the selected runner. since the Volume % will usually change much more often than the Price of the selection, the time (X-axes) of the Price and Volume graphs are at different scales.

• Refresh Rate - better termed Refresh Delay, since it is actually the time-gap between receiving a response from the API server and making the next call.
  So, if the Refresh Rate is 1 second and it takes one second to send a Request and Receive a response (the Latency) then the market display (Current Prices, Last Price Matched, and the Graph) will refresh every 2 seconds.
  
  We set the absolute minimum Refresh to 0 milliseconds, ... 0 on the dropdown, which means that as, as soon as your Tracker receives a response from the API server, it makes its next call for new data.
  With a fairly standard 2Mb connection this will update the graph and price displays about 3 times per second.
  You can change the Refresh Rate at any time for any Tracker , via its Refresh Rate dropdown.
  
• Last Refreshed Time - this Displays the timeStamp attached Marker Data most recently returned from the API Server to the current Tracker.
  
  




• Center Ladder - passing your Mouse or Touch pad over the icon (no need to click) will adjust the Betting Ladder to (approximately) center on the Last Matched Price of the runner you're tracking.
  
  You can also Center the ladder by clicking anywhere on the central column of prices.
  
• Last Matched Price - The Last Matched Price .... not much to be said, except that clicking anywhere in this column will Center the Ladder, but does nothing in terms of betting transactions.
  
• Betting Enable/Disable Button - As a Safety Measure, whenever you Open (or close) a Tracker, OneClick Betting is disabled.
  
  When OneClick betting is Disabled the Status text shows 'OFF' in gray and the Enable/Disable button shows 'Enable':
  When OneClick betting is Enable the Status text shows 'ON' in red and the Enable/Disable button shows 'Disable':
  
  In the Disabled state no Bets can be placed by clicking on either the Traditional Betting Buttons or the Ladder, but bets can be cancelled at any time.
  
  You can switch between Enabled and Disabled states at amy time while the Tracker is open.
  
• Stake Dropdown - The Stake Dropdown allows you to quickly select your Stake without using the Keyboard.
  
  

  ;

  It shows, as its highest value, the Maximum Display Stake that you select in your User Defaults Panel, and attempts to make suitable increments available. For example if you choose 300 as your your maximum Display Stake the dropdown will show 300, 250, 200, 150, 100, 90, 80, 70, 60, 50, 40, 30, 20, 19 .... and so on down to 2. If you need a Stake that isn't present on the Dropdown, you can simply over type the Stake Dropdown. Whenever you open a new Tracker the Stake Dropdown shows your Maximum Liability as the Selected value.

  
  
• Click to Lay(2) - This is our Ladder Interface, which is designed to enhance your ability to Back or Lay at your chosen odds quickly, and with the minimum of effort.
  
  All Ladders on either Single or Event Trackers show the 'Full Market Depth' ... i.e. all UnMatched bets currently waiting for this runner in this event on Betfair.
  
  

  Assuming that OneClick betting is Enabled for this Tracker, clicking in this (pink) column will place a Lay Order at the odds indicated (2.58 in this image) to the Stake or Liability set in your Stake DropDown ... (40 Liability in the above image) If, during transmission a better Lay price, e.g. 2.52 becomes available then that price will be Layed, and if all of the available stakes at 2.58 are matched before your order reaches the API server, then your Order will be placed, but not Matched ... as in this image. In this image we have already placed an Unmatched Lay order at 2.58 at a Stake of 25, in anticipation of the price dropping to this level. The outcome of your offer will be indicated, on the Matched / unMatched Bets Panel, the Profit / Loss Panel, and the Latest Bet display. The Ladder interface ignores any prices that you may have set in the Min Back Odds or Max Lay Odds boxes or the +/- Ticks dropdown. Logical really, since you have, by definition, selected your required odds on the Ladder, and the Ladder isn't vulnerable to 'Trap Prices'. However, the Ladder does respect your Maximum Liability. So, for example, if we had set our Maximum Liability to £50 and we tried to Lay at 1.91 to a stake of £100, the stake would be automatically reduced to £55.49. When this happens you are warned of this adjustment by a pop-up.



• Click to Cancel unMatched Lay - the total stake for any unMatched Lays on the current Selection at a price are shown in the appropriate box in this column. To save space the stake is rounded to the nearest whole number.
  
  Clicking on entries in this column will Cancel all of your unMatched Lays at this price (on this runner).
  
  In this example we have only one Lay of £100 at 1.76, but if our stake was made up of two Lays, one for £20 and another for £80 at the same odds, then clicking on the box in this column would cancel BOTH.
  
  Unmatched Lays or Backs can be cancelled at any time, even when other Betting functions are disabled.
  
  If you wished to cancel only one of the Lay bets, then you can do that be clicking on it on the unMatched Bets Panel, where each individual unMatched bet is listed.
  
• Click to Back(2) - i.e. the blue column, will place a Back Offer at the price selected, subject to the same conditions as in Click To Lay (above).
  
• Stake / Liability Dropdown -

  A new Option in all Event and Single Trackers is a dropdown that allows you to select whether your Bets are submitted to a Stake or to a Liability. Obviously when placing a Back Bet, stake = liability, but when submitting a Lay, it can be quite useful to bet to a Liability. MTPro calculates the appropriate Stake for your Selected Liability before submitting the bet. Unless you specify otherwise, all Trackers open with the stake mode set to 'Stake', but you can change this if you wish by setting 'Liability' on your Defaults Panel.

• Click to Cancel unMatched Back - cancels all unMatched Backs for the current Selection at the indicated price.
  
  As with unMatched Lays, if you have two or more unMatched Backs at the same price, you can also cancel them individually at the unMatched Bets Panel.
  
• Matched / unMatched Bets -
  
  

  Matched Backs and or Lays for the current selection are aggregated and displayed as the Average Back and/or Lay Price, and the Total Liability and Total potential profit. Each individual unMatched Back and/or Lay is listed, and they can be cancelled by clicking on them at any time ... even when other Betting functions are disabled.

• Click to Cancel unMatched Bets - Does just that, so that you can cancel individual bets.
• Betfair Starting Price (BSP)Tab - On every Event or Single Tracker there is now a new BSP tab:
  
  

  If there is a BSP market for this market (currently - 18 December 2007 - only UK Horse Racing Win markets), the BSP Tab will be enabled. As new BSP markets are rolled-out by Betfair, their BSP Tabs will be automatically enabled.
  If there is no BSP Market for this event the BSP Tab is disabled

  
  
  MTPro has all the functionality necessary to place, track, and Hedge / Green both' Market On Close' and 'Limit on Close' BSP bets.
  
  Full details of this funtionality are at: Betfair Starting Prices.
• Matched / unMatched Profit/Loss -

  shows your positions on this selection if the selection Wins its event and if it Loses its event. The Matched columns show your current position, and the '+ unMatched' columns show your position if all of your currently unMatched bets become Matched.

• OneClick Greening/Hedging - clicking on the 'Greening' Tab opens a Panel where you can 'Green Up' or hedge any currently Matched Bets on this Selection. Obviously, if you have no Matched bets, you have nothing to Green, and the Greening Panel will just look like this, with the 'Hedge' and 'Equalize' buttons disabled:
  
  
  
  but if you do have Matched bets and you were lucky (or skillful) enough to Back at higher than the current Lay odds, it will look like something like this:
  
  
  
  and you now have the opportunity to 'Green Up', either locking-in a guaranteed equal profit whether the Runner wins or loses its event, or hedging all of your liability, or your liability plus some proportion of your potential profit.
  
  A full description of the Greening / Hedging functions is here
• Latest Bet - if your Latest transaction via this Tracker was a Back or a Lay, this panel shows whether it was a Back or a Lay , the odds requested, and the amount matched.
  In the image, none of our offer was accepted so the Panel shows 0.0, but the Order has been placed, as can be seen from the Bet Display and Profit/Loss panels.
  
  If your last Transaction was a Bet Cancellation, this Panel shows the Cancellation.
  
  This Panel may seem somewhat redundant, however, it's a useful indicator when you have the 'Greening Tab' open and the Bet Display panel is temporarily obscured.
• Keep Bets - Bet Peristence Dropdown
  
  
  For most Betfair Markets that turn InPlay, (currently - 16 December 2007 - excepting Greyhound Racing and Australian events ) you now have the opportunity to Keep your UnMatched bets after the Market goes InPlay.
  
  There are two kinds of 'Keep' bets: InPlay (IP) Keep Bets and Starting Price (SP) Keep Bets. Both are featured on MTPro.
  
  On opening any Event or Single Tracker, default MTPro default choice for Keep Bets is 'None', which means that bets are simply handled as normal Exchange bets,
  
  
  

  SP Keep Bets: These are available only on Markets where there is a Betfair Starting Price. Basically your UnMatched Exchange Bet is converted at InPlay into a BSP Market On Close bet and matched at the Betfair Starting Price. An SP Keep Bet behaves similarly to a normal Exchange bet ... i.e. you can place it via the Ladder or Traditional Interface, apply a Fill or Kill limit, and Cancel it at any time up to the 'Off)', But if it is still UnMatched when the market turns InPlay then it is Matched at the BSP, so obviously cannot be cancelled after that point. On MTPro, you can choose to submit an ordinary Exchange Bet as an SP Keep Bet by Selecting 'BSP' from the 'Keep' dropdown before submitting your bet. The BSP option only shows on the dropdown if this is a BSP market):

  
  
  

  IP Keep Bets: IP Keep Bets are simply normal Exchange Bets, except that they 'Persist' (i.e. the don't lapse) when the Market goes InPlay. Even when the Market goes InPlay, you can still cancel them unless they have been matched. To make your Bet an IP Keep Bet, simply select 'Odds' from the Keep dropdown before placing your bet via the Ladder or Traditional Interface:

  
  
  Keep Bets show in the Bets Tab and (when matched) in the Greening Tab just like normal Exchange Bets.

• Manual Bet Refresh - Clicking this button will instantly update the Bet Display Panel and Profit / Loss Panels, so that, even if you have set a fairly slow Bet Display Refresh Rate, you can get an instant update of your current position.
  
  The Bet Display Panel and Profit / Loss Panel are also updated automatically, regardless of Bet Refresh Rate, whenever you open a Tracker, Place a Bet, or Cancel a Bet.
• Fill or Kill
  
  

  		All Single and Event Trackers now have a 'Fill or Kill' option. Fill or Kill simply means that, when you submit a bet, you can specify a period of time after which any Unmatched portion of the bet will be cancelled. On our Trackers, the period before the kill can be anything between 0 and 60 seconds (selected from the dropdown). Trackers open with Fill or Kill disabled (dropdown shows 'Off') To Enable Fill or Kill choose the period to delay before 'killing' your bet. Enabled / disabled state and the Kill delay apply only to their own Tracker, so, if you have more than one Tracker open, you can have a Fill or Kill enabled in one and not in the other, or Fill or Kill enabled in both, but one set to Kill after, say 5 seconds and the other after 30. >
  The Fill or Kill process runs in the background for as long as MTPro is open, so, if you have placed a bet with, say a 60 second Fill or Kill in a Tracker, and you then close that Tracker, the bet will still be cancelled after 60 seconds, so long as you haven't closed MTPro altogether. On Event Trackers, you can set, say, a 5 second Fill or Kill when betting on one runner, then choose a different period or disable Fill or Kill (by selectin 'Off' on the dropdown) when betting on another runner. A Fill or Kill set to a very low period, e.g 0 or 1 second is particularly useful when betting InPlay, since you you can place your bet offer when the event is at a current state-of-play with reasonable confidence that, if unmatched, the bet will be cancelled before the state-of-play changes dramatically against you.



• +/- Ticks - this applies to the 'Traditional' (button) Betting Interface, but not to the Ladder, where its use would be redundant.
  
  

  Allows you to select a Number of 'Ticks' ... odds increments, above or below the current Best Odds at which your bet offer will be made. The Ticks are applied after you've clicked a Back or Lay offer, so, if, for example you've chosen a +/- value of 3 and you click the Lay Button at 1.26, it will adjust your offer price Down to 1.23, and if you've clicked the Back button at 1.26 it will adjust your offer Up to 1.29.

  
  
• Min Back Odds -again, this applies only to the 'Traditional' Interface, not to the Ladder.
  
  In this box you can enter the Minimum Back odds that you want to back the selection at.
  As well as allowing you to set the odds you want, rather than just accepting those on offer, this is a useful Safety Feature, particularly in rapidly changing markets, such as InPlay horse racing.
  
  If you don't set Minimum Back odds (or +/- Ticks) you could find yourself backing at much lower odds than you intended if the price suddenly changes just as you're clicking.
  
• Max Lay Odds - more or less the same functionality and use as Min Back Odds (above).
  
  
  For each of these three Options : +/- Ticks; Min Back Odds; and Max Lay Odds; it is almost always more convenient, quicker, and safer, to use the Ladder Interface.
  
  So why do we have both?
  Well, some people prefer the Traditional Interface.
  
  But the main reason is that when the action gets really frantic, for example in InPlay horse racing, the betting can cover such an enormous range of prices so rapidly that it's almost impossible to keep the Ladder centered on the current prices.
  
  Theoretically we could always keep the current prices centered and make the betting parts of the ladder adjust to them, but this would present a big problem, since the prices that you click to place a bet would be constantly changing position, and there would be huge scope for error.
  
  So our best solution is to use the Ladder for almost all Betting functions, but then, if things get too frantic, switch over to using the 'Traditional' Interface.
  
• Current Funds - displays your 'Available to Bet' funds for the Exchange of the current Market (UK/Global or Australian).
  Does not refresh automatically, but can be Refreshed by clicking the icon to the left.
  
  Can be removed via the 'User Defaults' panel.
