A Place Back File - Doesn't look right

[smgreyuk]

Hi,

I am trying to do the following:

1. Place a Back Bet for the Last Traded Price (using the SV LTP) on the horse ranked one place below the placed pay out positions (So for 7 runners this would be the horse in 3rd Fave Position, if 8 Runners the horse in 4th Fave Position and so on

2. I want this bet to fire off 10 seconds after the off

3. To check the price spread is no more than 30 ticks ( I believe this is the part that's going wrong)

4. Bet at the last traded price

I recorded the Lay Price also at 10 seconds from the off to debug.

The following happened for 2 out of the 3 races:

24/09/2025 16:45:34: [G_Auto 1] : Store Value (Shared) for market: LTP = 3.6
24/09/2025 16:45:34: [G_Auto 1] : Store Value (Shared) for market: Lay Price = 3.75
24/09/2025 16:45:34: [G_Auto 1] : Store Value (Shared) for market: LTP = 2.8
24/09/2025 16:45:34: [G_Auto 1] : Store Value (Shared) for market: Lay Price = 400
24/09/2025 16:45:35: [G_Auto 1] : £ 10.00 Back bet placed on Likealot at 2.8. Entirely unmatched when it initially reached the market. Ref: 10003
24/09/2025 16:45:35: [G_Auto 1] : £ 10.00 Back bet placed on Music Piece at 3.6. Entirely unmatched when it initially reached the market. Ref: 10004

My questions are

Why is the LTP less than the lay price for one of the horses?

Why is the Lay Price so far out at 400 when I put a condition in to look out for the spread for 30 ticks?

Why is it putting on two Back Bets in the first place? ( I only selected the one horse in the relevant position )

Could someone please work out what I am doing wrong? Thank you

The LTP was the back price? LTP depends on someone either placing a back or lay.

Do you mean the 3rd/4th/5th fav at that moment, or based on the SP?

You need to fix this bit. Your group is for one or more to be true so this will trigger in any race, as every race will have either >3 or <7 selections.

You need to fix this bit because this is checking there is at least 30 ticks gap, not less than.

You need to save the LTP stored value in its own separate line before the trigger rules. At the moment it's only fortuitously storing the LTP on your second line due to your error in the number of selections condition, then using this for the remaining qualifying lines. This is why it's triggering twice.

You're only allowing 1 sec for the trigger rule, between 10 and 11 secs into play. You might want to extend this to avoid situations where the market does not refresh within this given timeframe.

Hi jamesedwards:

I have made all the changes, thank you.

Now regarding

"You need to fix this bit because this is checking there is at least 30 ticks gap, not less than."

I am not saying you are wrong, I am saying I may not have fully grasped how to do the following

"I am trying to only place the back bet when the back price is 30 ticks away from the lay price

For instance say the back price is 3 and the lay price is 4 (at 10 seconds), that's a gap of 20 ticks at that time, that's where I want the condition to be true.

Another example - say the back price is 3 and the lay price is 4.5 (at 10 seconds), that's a gap of 30 ticks on the nose at that time, that's also where I want the condition to be true.

But say the back price is 3 and the lay price is 4.55 (at 10 seconds), that's a gap of 31 ticks, that's where I want the condition to be false"


I searched around the forum and it appears that another user had the same confusion as me and thought of it the exact same way as I did - viewtopic.php?t=13432

I shall therefore use jimbt's approach of using the historic relative odds condition as that appeared to work for that user
I notice it uses "greater than" rather than my "less than" - I think the confusion is how the greater than or less than is combined with minus or plus, I just fail to visually grasp what all that means

I shall therefore use jimbt's approach of using the historic relative odds condition as that appeared to work for that user
I notice it uses "greater than" rather than my "less than" - I think the confusion is how the greater than or less than is combined with minus or plus, I just fail to visually grasp what all that means

Thanks again

All you needed to do was to change it from "less than" to "greater than".

So [back price] is greater than [lay price minus 30 ticks].

This way if the gap between the two prices is greater than 30 ticks then it will not fire. Previously you had this around the wrong way because you had it set to [back price] is less than [lay price minus 30 ticks].

Yep, it’s starting to make sense. The more I thought about it, the more I could visualise what it was doing with the values.

Thank you again
