Stop Loss

Postby kapilay » Fri Oct 22, 2010 1:58 pm

I was just wondering how the stop loss is calculated. If I lay a horse in running at odds of 5 with a stop loss set at, say 25%. When will the stop be triggered?

Often the difference between Back and Lay odds in running can be quite large. So, if the Back Odds fall to, say 2.5, and the Lay Odds are up at around 20, what will happen?

Many thanks.

The stop loss will be triggered at ((5-1) X 0.75)+1 = 4

When the stop loss bet is a back bet then the stop loss will be triggered if the best back odds go down to 4 or below and will be placed at the best back odds plus 1 tick. If the odds go down to 2.5 then the stop loss bet will be placed at 2.52, it would be far too risky to place it at 20 as in your example.

Sorry, I've just realised I've answered this incorrectly (I've answered it as if the first bet was a back bet). :oops: Here is the correct answer.

The stop loss will be triggered at ((5-1) X 0.75)+1 = 4

When the stop loss bet is a back bet then the stop loss will be triggered if the best lay odds go down to 4 or below and will be placed at the best lay odds minus 1 tick. If the odds go down to 2.5 then the stop loss bet will be placed at 2.48.

Thanks for the quick response, Gary.

Is there any way to get more control over the stop loss - in 2 ways that immediately come to mind.

1) Time: I want the stop to trigger after the race has run for a certain number of seconds.

2) The difference between back and lay odds: The user could be allowed to set the spread between the two numbers, which means that the stop would only trigger if the SL limit was reached AND if the spread was less than set by the user.

At the moment the stop is really only useful pre-race. It can be quite erratic and costly in running.

Many thanks.

Sorry, neither of those options are available in the software at the moment. I can consider them for a future release.

I've never thought the stop loss was particularly useful in running due to the volatile nature. I am however making improvements to make it more viable, see http://www.gruss-software.co.uk/forum/v ... =desperate for example.

Sports betting software from Gruss Software


The strength of Gruss Software is that it’s been designed by one of you, a frustrated sports punter, and then developed by listening to dozens of like-minded enthusiasts.

Gruss is owned and run by brothers Gary and Mark Russell. Gary discovered Betfair in 2004 and soon realised that using bespoke software to place bets was much more efficient than merely placing them through the website.

Gary built his own software and then enhanced its features after trialling it through other Betfair users and reacting to their improvement ideas, something that still happens today.

He started making a small monthly charge so he could work on it full-time and then recruited Mark to help develop the products and Gruss Software was born.

We think it’s the best of its kind and so do a lot of our customers. But you can never stand still in this game and we’ll continue to improve the software if any more great ideas emerge.
