Bots, ARRRRRGGGGGGHHHHHHHHHHHHHHH

Betfair is eating itself imo

I don't understand the problem - you put up a price that you think is reasonable
and a bot tops you - what's wrong with that? If your price is correct, your bet will
be taken sooner or later and the bot's owner will go out of business because his price
is incorrect.

A bot isn't cleverer than you. It's only as clever as the person that wrote it.

personally i think the bots are betfair

I don't understand the problem

The problem is the OP doesn't want better prices than his.

My problem with bots is flickering prices. Prices that appear then disappear in a second or so, and can do so hundreds of times. I assume bots trying to spoof other bots, but it's annoying.

I trade tournaments quite a bit and have bets taken by bots all the time. It's happened 3 or 4 times today already. Typically there will be 3 or 4 bets all at the same time, and all for the same amount on an outcome that might trade once an hour.

% of bets taken by bots?.  Dunno but when you see your lay bet sliced into a dozen same size pieces it does make you think who/what am I competing against?

With the bots the price often changes as you click on it ie 1.35 showing click you get 1.32 etc

also you put in to back at i.e  1.38 the market in the 5 sec lapse goes to 1.33/34
you put in to lay at i.e 1.38 the market in the lapse goes to 1.41/42

This has often made me think that are we all betting against each other/or separate bots
designed against only your account.
  As we all know you get matched at 1.38    1.39/1.4 will automatically appear after 1/4 of a second no delay
even a guesser will get a market move right 3 times out of ten on here you are always wrong.

Surely we'll reach peak bot at some point?

Im0 betfair need to weigh up:

yes the betfair bot GETS THE LOT.

But if all the players give up because they can't compete,,, what's left?

3 to 5% of something is better than 100% of nothing Betfair Bots

Bots don't work for the common good either  - they will always try to out compete you .

nay good if youre both otherwise happy to 'share' a price .

My experience is, overall bots do tend to kill secondary markets by driving out human layers. That's what they're designed to do - establish a monopoly by deterring competition.

Superficially, yes - by front running you they are improving the overall site offer. You're not going to get much sympathy moaning that you can't lay 7.8 because someone's offering 8.0. But in practice, what they're trying to do is drive you out of the market - at which point they revert to their terrible starting point prices. The 8.0 was just there to get you to go away so they could offer 5.5 with no competition.

They drive humans out by offering them a choice of competing at razor thin margins or not getting matched.

Event the bots gave up on a lot of the side markets I used to seed.  As frustrating as they were to compete against, the biggest problem is still the lack of opinionated backer money.

They drive humans out by offering them a choice of competing at razor thin margins or not getting matched.

Basically, one type of shark moaning about another type of shark, instead of working out where all the fish have gone.

Point to the bit where I'm moaning. This is just my view of how the situation's ended up. No one has a moral obligation to let me lay what's probably a 9.0 shot at 7.8.

In practice, the result in a lot of side markets (not all though - some have been improved) is that they've withered away because the bots have driven out competition and contributed to a liquidity spiral.

Something odd in the Ashes series winner market yesterday. The total traded (in Aus $) kept going up and down by thee same amount (about $150) every couple of seconds and this went on for hours. I assume it was a bot making a trade then reversing it. Which implies it was a bf bot.

Defo not a caching issue?  There have been numerous instances before where the API has flashed (and I do mean flashed) up old prices.

If a bot jumps in front of your 7.8 lay to lay at 8.0 surely said bot risks giving away value and being taken?

liquidity declines have nothing to do with bots.  The exchange model is perfect for low margin high turnover layers (bots or otherwise), they just require to offer slightly better odds than the books.  Betfair are disrupting the model by advertising "we have the best odds" and then diverting new customers to their sportsbook.

"Something odd in the Ashes series winner market yesterday. The total traded (in Aus $) kept going up and down by thee same amount (about $150) every couple of seconds and this went on for hours. I assume it was a bot making a trade then reversing it. Which implies it was a bf bot. "

This is caused by the design of the back end system. For fault tolerance and other reasons, Bf use multiple servers, each holding it's own snapshot of the market, which is synchronised every so often ( or not ).

Each api request for market data can be passed on to any of the servers and will return the market data held on that server. I have noticed that in
quiet markets, data from one call can be older than data from the previous call ( data is time stamped, although Betfair say this field is not valid )

In my application I discard any 'old' data, seems like the webpage does not and thus you are seeing a less than up to date set of data.
