The fat fingers thread

[cybernet69]

what on earth happened here?

bev 14:30

You often get some strange goings on in a 5f race, especially where there is no odds on favourite.

Many punters will just lay the field @ 1.05 prior to the off.

Its a very short race and mistakes with regard to odds will happen as people cant type fast enough.

I did not trade that race. But managed to look at bf charts before it got suspended. And it looked to me that at least two 1.01 traded before the off and not inplay.

I've had a look at the data, I didn't notice anything at the time

[Euler]

Looks like it traded at 1.01 when the market opened. I can see several spikes at open, i.e. when the market was first put up on the exchange.

[mpendle]

Hmm, seems a bit fishy that one.

According to the data from the API, at 14:52:30 about £15 was matched at 1.01, along with some at 110, but nothing between.

There was certainly money in the order book that should have been matched before any at 1.01.

- maybe an API glitch ?

Just returning to this odd Misu Mac situation.
I have looked at the Betfair Data files and it confirms that Misu Mac was matched at 1.01 pre off. 32 was the next lowest matched, which was the figure Peter mentioned.
What is odd though is that there would have certainly been money between 32 and 1.01 that doesnt appear to have been matched.
I will seek an explanation from Betfair.

Anyone try and back Midnight Rider? I put my order in at 8.6 came back later and saw the price was at around 4.2, so I left it, came back later and got some matched at 8.6!

If anybody wonders what went on at the 7f Handicap race at Leicester today, here's why:

That's six pages of bets on Als Memory.

I had "fixed" something in my program that I thought was innocent. ...Until I received a message on my mobile that something was wrong. Rushed over to the computer, and tried to get out. I feel very lucky that it didn't cost more.

Just discovered the bug: just one character, an exclamation mark (!) was missing

Does anybody have a graph of that race?

Sorry to hear about the loss; I have the same tee shirt! (although I put that much through, I forced the price down! I was sitting in dublin airport at the time and will never forget it!)

Are you using Excel? if so, one thing I put in all my spreadsheets was a simple catch all whereby it looked up the total P&L for the day based on a calculation that checked the amount in cell c6. Depending upon which strategy i was using I could set a value so that my losses could never exceed a preset amount. Just provides peace of mind

Regards
Peter

No, not using excel but I do have something similar, hence the warning on my cell phone.

glad I was near the computer. Being in an airport when the proverbial shit hits the fan sounds like a nightmare!

Fat Fingers there...commentator suggested it may do well..
dip occurred as it went in play..

[LeTiss]

That's quite impressive

We don't see fat fingers with the regularity we used to. Or perhaps we do, it's just my imagination!

[PeterLe]

Think they are still there Lt..
I was tradig some of the others...but after the comments I backed it at about 23's I think (£10)..and left an SP in a few ticks below..
It didnt show it in the overview screen but I think it went as low as 1.37??

The best days for a fat finger were before BF introduced the 'Keep' bets where your bet remains in the market at the off as when the market was cleared out of bets it was not uncommon to see people taking 1.01.

I made that error once by hitting the green up button just as the market turned inplay, there was nothing to green up against bar very low bets fired in by automation as soon as the market reopened. Probably paid for Peter's family takeaway that day

I fat fingered yesterday

Wrong bot. Wrong market. Thankfully I realised straight away and I corrected it after one cycle. Made someone else very happy, so always look on the bright side of life.

Dented my psychology for a while. Thankfully (once I applied the right ones) bots are immune to emotion. I know if I was trading manually I would have chased a recovery because I was angry with myself for making a mistake.

Someone just lost their house...

Greyhounds - 15:07 at Hove. Maireads Secure was briefly trading at 790/1, and £200 was matched. I was just glancing at my bot when I saw it in disbelief, but by the time I realised what was happening, it was too late to get in on the action. After the money was taken, the price then normalised in the teens.

It won.

I think someone will be having words with their bot.
