Number of horses
« on: 03 Dec 2015, 01:22 »
If i wanted to add a condition in a trigger which is like "if the number of horses in the race with odds < 10.0 is greater than 3"  ..then back the favourite.

How can I do it ?
I couldn't find a standard variable which shows how to access the number of horses based on a constant odds value.

Thanks

Hi
It's matching_number. Your example:

all matching selections
selections back price is less than 10.00
and selections trigger expression matching_number is greater than 3
and selections rank is equal to 1

Thanks very much for your reply.

Also..is there a wait to delay a trigger based on a race variable.
So I am only triggering a bet in-play (market status set to in-play), but I don't want the trigger to start running as soon as the race starts, but want to wait for say 1 minute.
And this time wait could be different based on the length of the race > i.e a 2mile race may have wait time of 1 minute, but a shorter race may have a wait time of 30secs.

Would i need to access the Race description to determine this ? e..g 13:45 2m3f Hcap Chase

Thanks

You will want to base the time of a calculation based of the market_length value

Starting off to keep it simple.

Say I want a delay of 45 seconds before an in-play trigger starts. would the following condition work ( I found an example in the online help)

...and Selection's Trigger Expression (( now-time - event_off)/0.0001157)) is greater than 45

Thanks.

hi
and markets 'minutes before the off is equal or less than .75
would be better.
100/60*45
and for your first question
and trigger expression s_4_back_price is less than 10.00
so the first 3 favs must be less than 10.00
simple with no complications.

Hi mcbee
much easier, thanks.
just to clarify, r_4_back_price ?

please forgive me but I think trader21 was asking in-play so just a minor change to:
and markets minutes since the off is equal or greater than .75

and can you confirm this is best way for the original question for a variable to return the number of horses based on a constant odds value, instead of matching_number to previous conditions?

cheers
Mark

ps trader21 if you search the forum for "race length" or "market_length" referred to by liltbrockie you will find some interesting material.

Hello .

Just to clarify what I meant.
Horse race has 10 runners > back prices between say 3.5 up to 15.0
As race progresses the prices change as horses drift out..

So I want to only trigger my bet once there are max of 4 runners below odds of 10.0
I.e the other 6 runners have drifted to odds past 10.0

So I am only backing the favourite, but I am keeping tabs on the other runners and only place my bet when there are 4 runners below odds of 10.0
So I was asking for the condition where I could check how many runners there are with odds less than a certain value.

Thanks for help so far.
