Ascot 1.20

1st 5 French Opera 5-4 F 2nd 3 Edgeover 33-1


When I posted this early on .....I did sums wrongly :(




STAKE BACK on FRENCH opera winning + 124.57 points
WIN PROFIT 1.5 X 124.57 - 5 % + 177.51

BANK after losing place lay
on FO BF 612.52 before 1.40 race
----------

BANK before 1.40 race 914.60 points

For some daft reason I worked out the liability on place lay on FRENCH OPERA would cost 98.28 points.....but it was only 22.22 liabilty on lay( 63 x 0.56 ....not 1.56)


Therefore the CLOSING BANK should be 1173.06 points

Just another point worthy of note to thoses interested in KELLY etc

On my first ATTEMPT using KELLY.....had I not did PLACE bets or SFC bets ( usually done instead of place bets)....and put FULL KELLY stake on.....I would have been roughly 80 points worse off.

On ATTEMPT 2 ....there were 3 winners today where I only put HALF of KELLY stake on the WIN...and put half on PLACE or SFCS.........Had I put FULLY KELLY stakes on all horses on attempt 2.....the CLOSING BANK would be higher by -

FRENCH OPERA ....I should have ignored the place lay ....COST 22 points

DEEP PURPLE - extra win profit 211.18 + stake wasted on SFCS57 = cost 268 points
ON THE LOOSE .extra win profit 339.26 - place return 77.35 = COST 262 points


Therefore CLOSING BANK would have been up by a further 552 points


Now this was on a poor day for me............................so when I hit form ...and confidence grows.....the profit that can be achieved with KELLY can be significantly higher.......

In effect if I cut out PLACE bets and SFC bets would be 552 points less 80 on attempt 1.........ie 472 points better off .....

It is important to note this......as I am not applying KELLY strictly in accordance with FULL STAKING..........

So from now on I will only do WIN bets.

Whilst its very nice to have an "efficient" staking plan. I will give you this to ponder. If you are in fact using a staking system with negative expectation then i would expect the kelly system is the best system to maximise ones loses. I would think it best first to identify whether one was profitable first.

boba - no negative expectations......just some caution initially on KELLY being applied to horse racing.....I'm confident in my own ability ....it is KELLY I am wary of!

k well best of luck. I only deal with football and in general level staking with incremental increases are the best way to go. Some reason for this maybe explained by the fact that the asian bookies taking your bets are also following you in. So it is better to have more predicatable profits in some sense.

boba
When: 31 Oct 09 20:27
Heres something else to think about with regards to kelly. If you place approximately 2*k where k is the k fraction on a perfect information bet you are guaranteed to make no money. Placing more then twice the kelly fraction and you will in fact lose money.

Thanks Paddy ....need all the luck we can get with horse racing...!!!!

Boba - ......One of main things I like about KELLY is that it is staking based on VALUE ........as I have never been in favour of LEVEL STAKING, as why bet same say on odds on shot where narrow margin of value ....whereas , you place same stake on another horse where differential in value is far far higher .................just seems logical to me.

It also helps be stake in accordance with bank position.......................and that is something when you are in the heat of battle betting on horse races it is so easy to OVER STAKE ....WHEN WINNING AND WELL IN PROFIT ( this is what I have been weak on in past)....NOT CHASING etc ....

So in theory the combination of controlling staking AND betting more on value should work in my favour ( ATTEMPT 1 was me needing practice , as have not watched much racing last 12 months....and it is important to know what the current way races are being run at any point in season etc)

Thanks again for post ...GL with footy bets.

level staking is not necessarily fixed. more it operates on a number of levels. you will generally bet more on bigger percieved value. but it wll be stepwise. so u may have 1* bet 2* 3* etc. I am a great advocate of marking to market. If u blindly apply a rule like kelly when you are most wrong and most likely not to have value is when your percieved posistion differs wildly from the market. Just my 2 cents
By:

When: 31 Oct 09 20:43
boba - apparently you have to be ACCURATE on the probability of horse selection winning.....this is probably impossible.....you can only guess on probability IMO.....it is very subjective.......

So as long as I select horses I perceive as having a chance to win, based on factors I believe are relevant ( some of those factors are probably not accepted by most people setting odds or backing.....but that is irrelevant to me as I know from watching races and checking results that winning horses do tend to have such factors in their favour.....and that is all I need to know), then am reasonably ACCURATE on GUESS, then this should work for me.

Most of my selections that do run well....are spotted by me BEFORE the market starts to wade in on them.............so my odds generally are at value......as odds on such horses tend to reduce near off.

If I do get PROBABILITY wrong too often .......I will lose ......also if I select wrong horses the same will happen.......but i cannot be perfect on calculating the PROBABILITY of a horse winning......so will be interesting to see how good guessing on PROBABILITY works with KELLY.....]:) :D

Switching computer off now....thanks again for posts.

actually u are wrong if you are sufficently variable with regards to your probabilities even if on average you are profitable u can still lose using kellys. You need to have a measure of your uncertainty adjust for this.
By:
DFCIRONMAN
When: 31 Oct 09 21:05
boba- I think it is important to bear in mind that there is far higher amounts of VALUE with horse racing say compared to MATCH market in football matches.....so you can be not quite so accurate , as your margins are higher with winning horses ....or should I say the ones I pick are!

I'm a bit knackered now ....been on here too long......

So thanks again for posts ...good to try to make me think.....and good contribution to thread ....
