So Frustrating

[ajanthony]

Hello All,
I am becoming so frustrated. I want a simple set up that has a offset back bet/s with a few simple conditions about odds and WOM. These work, no issue.
I want to keep unmatched bets, that is no problem.
I want to close all positions if overall green profit is above $x and close all positions if loss is greater than $xx. (The loss is represented as profit less than minus $x in conditions).
No matter how I do this I get random results that swing from large profits to large losses.
What am I doing wrong?
Have attached some screenshots and can attach more detail if necessary.
Any help appreciated.
Regards,
Anthony

I'm not an expert, but until someone smart comes along with better advice, it sounds like your system thinks your up >5, tries to place the green up bet and gets poor execution such that now you're losing more than 3, and then tries to 'red up'

It might possibly have something to do with poor liquidity inplay in AU, or perhaps the IP bet delay is causing havoc, or maybe you arent refreshing fast enough. I'm not sure.

There are also some issues with your timing

1. Again, not an expert, but I think you want to Keep Unmatched Bets relative to event time. I dont think you can decide to Keep them once the market has gone IP?

2. The timing on your Close Profit rule is based on race time, whereas the Close Loss timing is based on IP time.

Thank you,
I have made those changes, will see what happens. The liquidity on most races has been reasonable today but I will test it again on UK and then on Aus Saturday races.
Much appreciated.

Good luck.

One idea I had was that you could run with only one of the greenups and see what happened, and another was if you ran it all before the start of the race and see if it performed properly, and see if you could learn something that way.

(Probably the best idea is to wait for someone who knows much better than I!)

If betting on multiple runners its usually best to use
Green all selection > green all profit condition
or
Close trade on selection with greening > close trade profit condition

Rather than a mixture like you currently have of
Close trade on selection with greening > green all profit condition


Also if you are greening up when the total profit across all runners (green all profit cond) is greater or less than
Do you have a condition on your back bet rule that checks these values have not yet been reached so another back bet isn't placed after you've greened up?

[ajanthony]

Thank you Dallas,
No, I don't have a condition that checks the value, that is maybe what is causing some of the problem. I don't know how to do that. I have fixed the greening condition and I can see in the conditions references to values but as mentioned don't know how to implement.
Your advice, as usual, would be very much appreciated.

Its just a case of adding a Green all (or close trade profit) cond to your back bet rule as well set up as shown here

Thank you Dallas,
Just had a look, should be able to sort that.

Perhaps the problem is you are trying to green up in-play. On in-play horse racing for example, Betfair add a 1-sec delay to all trades hitting the market meaning the price Bet Angel expected you to be able to green up at might be long gone. If in your favour then your trade will be matched at a better price than expected, but if it moves against you then it won't match at all until either the price moves back in your favour or Bet Angel tries to green-up again.

Hi,
I am doing some testing on a few strategies and testing on some US markets which I don't trade and don't normal test on either.
What I am finding is that even with a $50 liability back and lay parameter with a 15 tick offset the execution is a bit random. On some of the markets it is operating correctly but on some others the lay is $10 regardless off odds and no offset being placed. Is this something peculiar to the US that some of their tracks/markets have some form of restriction that does allow the correct execution of my rules.

US racing markets have much lower liquidity, especially if you are trading in-play. This makes getting matched at a decent price much more difficult, especially if you are looking to trade out again and 'green up'.

[ajanthony]

I do understand that but how would that effect the initial lay bet being greater in liability than my rules or not placing the offset.

I suspect it's to do with the Betfair in-play delay.

Perhaps the problem is you are trying to green up in-play. On in-play horse racing for example, Betfair add a 1-sec delay to all trades hitting the market meaning the price Bet Angel expected you to be able to green up at might be long gone. If in your favour then your trade will be matched at a better price than expected, but if it moves against you then it won't match at all until either the price moves back in your favour or Bet Angel tries to green-up again.
