This servant can be used on most types of markets but is typically suited for pre-off racing markets

The purpose of the servant is to highlight with a ‘Marker’ in the back or lay column on your ladder screen if the pressure of money waiting at the best 3 price has built up on one side of the book.

Once a 'Marker' is placed If the pressure maintains and its still at the same price for 5seconds the colour of the Marker will deepen, it will then do the same after 10 seconds, in slower moving markets this can indicate a slow and sustained build up of pressure.
After 15 seconds the 'Marker' will clear, if pressure is still there it will begin the process again.

If at anytime the pressure drops off from one of the best 3 price the ‘Marker’ will clear and be ready to re-trigger again once another build up of pressure occurs.

NB, due to the speed the price move in pre-off racing your unlikely to see a sustained build up of pressure and the deepening colour change of the markers except for higher liquidity markets like Cheltenham, Royal Ascot and the Grand National etc.

In addition to the servant which can be downloaded from the bottom of this post you’ll also need a ‘Ladder Settings file’ to display the ‘Markers’ on your ladder screen, this can also download near the bottom of the page.

The ladder settings file will continually look for ‘Stored Values (shared)’ from the servants rules, when it see’s a Stored Value it will display a Marker relevant to that value (then clear them if the stored value no longer exists).


Using the Servant

The servant uses Context selection so will run on whichever selection/s you choose simply by pointing your mouse cursor pointing at when you start the servant.

Once started on a selection the servant will then monitor it for a build-up of pressure on one side of the book, if this happens you will see a ‘marker’ in the form of the cell of the best price on that side of the book becoming shaded. In the image below you can see there are currently two selections were there is a build up of pressure on the lay side

What is Defined as Pressure?

This is when the money waiting at each of the best 3 prices on one side is significantly more than the money waiting on the other side of the book at the respective best 3 prices (so it’s far more sophisticated than just using WOM).

You can configure and ‘weight’ this anyway you want, but for the purposes of this example the Servant is configured to trigger when the money waiting at the two best prices are compared with each other and one side is 100% greater (ie, has double the waiting money the other side has), the money then waiting at the two second-best prices are compared against each other and this time one side must have 50% more money waiting, the same goes for the money waiting at the 3rd best prices.

Basically, only when the money waiting on one side of the book is 100% greater than the other at the best price, 50% greater at 2nd best price and 50% greater at 3rd best price will the servant trigger.

For example, in the image below you can see the marker has triggered on the lay side indicating there is upwards build-up of pressure because;
The money at the best back price (5.1) £133 is currently 100% greater than the money waiting at the best lay price (5.2) £96
The money at the 2nd best back price (5.0) £347 is currently 50% greater than the money waiting at the 2nd best lay price (5.3) £218
And the money at the 3rd best back price (4.9) £236 is also 50% greater than the money waiting at the 3rd best lay price (5.4) £99

How it Works

The servant's first rule is to stop all other servants so it doesn’t conflict with any other, including re-starting this one on the same selection, this rule will also clear any signal on the market and selection.

The rules file is then split into three more sections, 4 rules for the back side and 4 for the lay side, these are identical except for which side of the book they trigger on.


Back Pressure Marker 0-4secs rule – This rule uses 3 ‘Stored Value’ conditions to test if the money at the best 3 prices is greater on that side of the book as detailed further up this post, if you want to edit those values this is where you’d change it. It also has a ‘Signal Set’ condition to test if a signal named ‘backmarker’ is set, if not the rule can trigger

When it does trigger it will set a signal named ‘backmarker’ for the selection (so this rule can’t then trigger again until this signal is cleared) and set a signal on the market named ‘backtriggered’
It will also ‘Store a Value (Shared)’ named ‘backpressure04’,
When the ladder settings file see’s this stored value set it will display a ‘Marker’.

The Back Pressure Marker 5-9secs and Back Pressure Marker 10-14 secs rule contain the same three Stored Value conditions which are all configured the same, the only extra rule here is a ‘Signal Changed’ condition to test the signal named ‘backmarker’ changed between 4-5 secs ago,
(ie, this rule will trigger 5 secs after the first providing the pressure is still there and the signal hasn’t been cleared)
It will also store a value (shared) named ‘backpressure59’
When the ladder settings file see’s that it will display the relevant marker

The next rule does the same as the last but the ‘Signal Changed condition’ won’t allow it to trigger until 10 secs after the first, when this rule triggers is Stores a Value (Shared) named ‘backpressure1014’
Again when the ladder settings file see’s that it will display the relevant marker

Clear if Pressure Drops
Rule – This rule contains if it triggers will clear ALL signals and Stored Values, it has two conditions, one is a ‘Signal Set’ condition which tests the signal named ‘backtriggered’ is present (ie, there is a marker currently placed)

It then has a ‘Group’ of conditions which tests if ‘one or more condition within that group are false’,
The group contains the three ‘Stored Value conditions’ that test there is a pressure build up at the best 3 prices, if any of these conditions are no true it means the group will have a false condition and the rule will then be able to trigger.

The final section contains two rules two clear/reset the ‘Markers’ (depending on whether they were on the back/lay side)
Each has a 'Signal Changed' condition to test if the signal named 'backmarker or laymarker' changed 15 secs ago, if so the rule will trigger and clear all Signals and Stored Values.
ie, 15 secs after the Marker is placed if its still live this rule will clear it so the process can start again.

Pressure Marker.bls


Downloading & Using the Servants

To use these servants just click on the ASC Pressure Markers.Baf attachment links below and this will download them to your computer, then open your Servant Manager window and click the rules link at the top and then "Import a Rules File" as shown in the image, once imported it will now appear in your dropdown boxes and is ready to be started whenever required.

Once you have it imported into your Servant Manager it can be edited very easily simply by clicking on "Edit Rules File".

With any servant always run in practice mode first to ensure everything is working fine, and repeat this each time you make any changes.

See the following thread for step by step instructions on downloading and importing a servant into your Bet Angel, or see image below on where to import it in your Servant Manager.

TIP

To use the Markers on your existing ladder settings simply download the ladder setting file from the previous post and import it into your Bet Angel, then open your ladder settings editor and go on to the ‘Marker’ tab and copy how all the ‘Markers’ are configured into your existing ladder settings.

You just need to download both files, import the .bls on into your ladder settings (and select it)
and import the .baf into Guardian and apply it to your markets
