This is very nice 

If I have the math correct then the broadcasted data has 0.1 millisecond resolution (100 microseconds). It is sufficient for HFT (although 1 microsecond would be optimal).

Since nanosecond resolution is internally stored then I think broadcasting events with microsecond timestamping might be technically feasible if such demand arises from clients in future. Am I correct?

What's the time stamping precision of data feed at Kraken (seconds / milliseconds / microseconds)?

Dargo,

There is nothing about HFT that an ordinary bot should fear. Just like there is nothing that a discretionary trader should fear about an ordinary bot.

People who have advanced technology enjoy a fair advantage (not unfair). They worked hard, invested hard and now are harvesting fruits of their labour and risks taken. There is nothing unfair about gaining advantage through hard work and capital risking.

There are however ''tools'' that can put ordinary traders and bots at disadvantage, e.g. dark pools, if their volume is non / under-reported in the exchange feed.

Out of curiosity: does any of the two projects offer (partial) answers to this idea? https://bitcointalk.org/index.php?topic=313151.0

Last time I trolled was https://bitcointalk.org/index.php?topic=178336.msg2982733#msg2982733 when price reached 124 on Gox. I trolled the price might go down to 85 on BTC-e and to 90 on Bitstamp. It went to 85 and 75 respectively (due to Silk Road event).

The way I see things now (just trolling): about 50% odds of going to at least 360 very quickly and about 50% to go down below the last low of 110 on Gox. We'll know soon.

The way I see other things (just trolling) which MIGHT be of interest is 80% of S&P 500 will develop the first bearish wave within a few days. 80% probability is too low to go short right now but in a few days 80% probability MIGHT turn 99% probability.

Serious stuff. I will run on my bank tomorrow.

Not a proof, but if you play with ''satoshi nakamoto'' letters you arrive at ''so a man took a shit'' phrase (discovered by someone in another thread).

This phrase matches Bush's mentality.

TBF guys deal with Bitcoin. TBF people are large Bitcoin holders. I am probably calling for something that is not Bitcoin and might be contradictory to Bitcoin protocol. Although mining might be merged.

Surely it does not fuck up fungability of any crypto assest simply because such a crypto asset has not been yet devised. No protocol to my knowledge envisages this.

This mechanism would simply display a message that a legit owner of a crypto asset has tainted / locked / whatever his coins. Does it fuck up fungability? - I don't think so. Thieves might still exchange the tainted coins between themselves. Nobody could force you not to accept payment in tainted coins.




That does not mean messing with the coins which belong to someone else (that means ''messing'' / doing whatever pleases you with your own coins)!

It is perfectly fine to have a crypto coin's protocol that envisages for all the miners not to process transactions with tainted / locked coins.



That does not mean to be able to reverse a transaction. It only means the person who had originally tainted the coins (while still in his address / wallet) can in any point of time un-taint the coins which were / are in use by the thief.

Imagine the following situations:

1. You are a burglar. You are breaking into my house. When you do it I taint my coins. You put a gun in my head, I give you my private key. You and your buddies leave my premisses with my two cars. The next day you call me and tell ''hey, I stolen the coins that I cannot do much with unless you un-taint them''. They I say ''hey, I've got a proposition for you: bring one of my two cars you stole to me and I will un-taint a certain amount of coins for your kindness''.

2. You are doing business as an ''ethical authority'' in Iran. You caught me doing something illegal, e.g. selling alcohol. You confiscated my margarita drinks and my crypto coins. You want me dead for selling margaritas. I place you an offer. Let me live and I will un-taint my coins for you.

3. You are a kidnapper. You want my money. You and your mates are shooting at me, at my children and at my bodyguards. Imagine a real mess. People are bleeding to death. I happen to carry a small wireless device. I press a button and taint my coins. I can now negotiate. If you release my kids, I can un-taint some of the coins, if you release my wife (who is needed in a safe location to countersign the un-tainting of a larger portion of coins), I will un-taint another portion of the coins, etc.

These are just hypothetical examples showing that tainting the coins can be useful for people.



1. I have just painted my 5 euro bill black. I hear no police siren sound. Nothing happens. I wonder why  

2. ''Your government'' this and ''your government'' that - you know what? I don't have any government.

I am not suggesting what you imply I am doing. ''Reverse transactions or somehow render them useless for the receiver after having received them''? - where the heck did you get it from, dear?



This is how Bitcoin works. I do not want to mess with Bitcoins in your or my wallet.



Why central bank? Aren't crypto coins about eliminating central banks? Your imagination would take cryptocoins back in time.



Maybe you want to have a closer look at my post and conclude I do not want to get rid of any of Bitcoin advantages.



Imagine, you run a banking business. You have vaults full of notes. Robbers are drilling your vaults with drillers. You are sitting in a safe room. You have every right to press a magical button that will taint the notes deposited in your vault with paint. Why the paint? To make the robbers' lives miserable. Such stolen (and tainted) notes will be worth 1% of the original value on the market (someone will need to take pains to clean the notes, etc). Crime should not pay!

Now imagine robbers drilling your door while you are running your anti-FBI client. You simply taint your coins (you are the banker in the crypto realm) thus making the robbers' less profitable. How is that a crime?

I like your creative way of thinking a lot.

Never. I am a newbie in Bitcoin 

This is different on BTCChina. Heavy selling volume: smart traders selling, suckers buying.

It is neither about how to be a human nor how someone was or was not raised. It's about trading. Either you win or you lose. Is losing humane and winning sociopathic? I don't think so.

You should not care for the long term health of any market. You should not care for investors and normal people. You should only care for yourself and for here and now and how much profit you can make out of a bubble if it appears.

There isn't a bubble yet.

Woke up on time and managed to sell some of my BTC at 190.

BTCUSD trading has been very rewarding. Very good market

1. So if I had an exchange, I would get my data feed connected to tradingview and bitcoinwisdom so that my potential clients have charting of a reasonable quality for free. You simply can't trade well without charts.

2. After doing this, I would expect to get a few hundred Bitcoiners as my clients first. Unfortunately Bitcoiners do not trade frequently so my income from fees would be low (Bitcoiners just buy and hold for a few weeks).

3. Then I would avail my data feed and trading API to TT, CQG, IQ and others, so that my potential new clients not only can use simple charting but also can use algos. I would even get some income through commercially availing my data feed.

4. By doing point 3 I would immediately get access to tens of thousands of traders around the globe (non-Bitcoiners) as my potential clients. By doing point 3 I would reduce the risk of heavy CAPEX on infrastructure in the future as well.

5. Then I would do easy and cheap marketing hocus pocus and would get as a result a few thousand new (frequently transacting) clients.

6. The new frequently transacting traders would give me the best liquidity and lowest spreads among other exchanges. With this I would attract clients from Gox, Stamp and other major exchanges.

7. After two years I would have the most profitable exchange on the planet. Next I would sell the exchange to an institutional investor and retire.

I would like to see Kraken.

Yes, and Kraken needs time to grow. People need time to create new thinking pathways in their brains. I think - given the low quality of offering of the major exchanges - people are both ready and eager to create new connections. No financial effort should be put into advertising in this stage in my opinion.


There may come times when the current players, Kraken inclusive, will look for other types of clients, be them forex, stocks or futures traders. Maybe even Kraken will want to leverage their claim ''FOREX MEETS BITCOIN EXCHANGE'' one day and invest in advertising directed towards forex traders. If / when this happens the current bitcoin exchanges will need to add many many many features if they want to attract new clients. Tools available for traders at the current bitcoin exchanges are laughable at best (although Kraken seems to be best suited for new types of clients with their order types).

At the moment they should just create the official thread in Marketplace (not in Service announcement) and talk to clients. I would be interested to hear about their leverage trading offering. I would like to hear about their plans (if they have any) to improve charting on their website - their price history chart is a joke.

When they are technically ready with their features for forex, stocks and futures traders, they should start very very very cheap and smart marketing in carefully selected websites.
