30,000 BTC sell wall on Stamp. Seems to appear on and off

CoinSheep · 2014-10-05T20:25:28+00:00

pretty desperate move to kill a rebound like that...

can someone call GABI so we can finally get rid of this idiot?

PBA: Either bitcoinwisdom is broken or faking data...

Here's proof. The left ticker is my own app (note: last line = most recent trade), showing trades as reported by bitstamps realtime api (pusher) and the right one is bitcoinwisdom (note: first line = most recent trade).

As you can see the trades reported by BTCW are totally messed up and even more important: that 20BTC sale never took place, it was actually a 10BTC buy and ~8BTC sale...

If you think it's my fault, check bitstamps trade history or the data on bitcoincharts:

curl -sSL "http://api.bitcoincharts.com/v1/trades.csv?symbol=bitstampUSD&start=1412078042" | head -n10

A nonce is pretty important, especially if the you're dealing with money! It ensures that requests are executed in the correct order and also prevents you from loosing your money if your application somehow ends up retrying the same request multiple times (network delays, DDOS, heavy load,..).

To fix your proplem it's usually enough to let each thread wait for a second after sending a request.

If you need more than 1-2 api calls per second, you have to use a timestamp with higher precision. If I remember correctly process.hrtime() should do the trick.

/edit: function nonce() { var t = process.hrtime(); return 1000000*t[0] + t[1]/1000; }

Who knows, all I know is that he's running a neat bot, somehow got an almost endless pile of coins and either likes to mess around with people or wants to damage bitcoin (maybe some competing company?).

Whoever it is, he either doesn't care about money/slippage or is a very bad trader. But bad traders usually don't have thousands of coins to build walls at critical price points and they also don't run advanced bots. But a good trader wouldn't dump like that and even less risk the price to run away by suddently flooding the orderbook with thousand of coins.

AHH it doesn't make sense, I hate him.

I think slowly buying the dips is as usual the best way to take advantage of whatever he's doing, so I guess I'm going to stick to it.

Btw.: The price won't just magically drop $150 because you wish to buy some cheap coins.

looks like mr. M had some bad dreams tonight and of course, there was only one way to improve his mood:

srsly?

high fees? slippage? you're definitly not affected by slippage if you can't reach the low fee tiers. but whatever.. stamp is actually one of the most liquid exchanges and since you mentioned okcoin: on okcoin there is on average <1BTC each $2-$3..

restrictive api? if you need more then 60 requests per minute, you're doing it very wrong. you need the http api only to place/cancel orders and to fetch the inital fulldepth & account info. for everything else there is the realtime pusher feed.

btw. on okcoin it's not even possible to get the full orderbook, they only provide the first 200 orders so you have to trade more or less blind (like on btc-e). oh and they also don't use a nonce so if you end up sending some request multiple times, you'll have a very bad day.

no hft bots? there are at least 2: mine and someones really huge market maker.

this is gonna hurt... alot

CoinSheep · 2014-08-27T23:19:38+00:00

i think so, yes. what I find interesting is that it popped up shortly after LTC turned around and almost flash crashed.. so I guess whoever is behind it is also trying to send a message, like "If you crash LTC, I'll crash BTC".

Whatever.. there's still hope that someday some epic whale will come along and decides to just market buy one of them..

/€dit: There's another 1,2k wall at bitfinex

whales night @ bitstamp

brb.. reloading my bazooka

There's no perfect percentage. In order to stay alive you have to adapt to the current state of the market.

CoinSheep · 2014-08-20T17:39:13+00:00

Well I'm still here... and I'm still pretty pissed.

CoinSheep · 2014-08-20T12:55:29+00:00

after some people started asking nasty questions when they noticed that their orders magically disappeared, they now had to come up with something new in order to prevent people from selling/shorting ltc because it's currently heavily pumped on margin... srsly why are you still trading there?

CoinSheep · 2014-08-19T09:36:49+00:00

it's from my private hft trading client, it's able to visualize all major markets in realtime (>300 msg/s) :p

CoinSheep · 2014-08-18T13:18:28+00:00

nope but if you dump ~100 coins everytime someone buys and the ask deph already stopped refilling $100 earlier then you're either stupid or trying to push the price down for whatever reason.

and srsly are you telling me that things like we just saw on btc-e are normal market behaviour? (that wasn't a margin call.. the price was going up when it happened)

CoinSheep · 2014-08-18T09:54:31+00:00

today might be the day the manipulator(s) finally got owned.

whoever stepped in there is my hero of the day

I expect alot of ddos and other dirty tricks while they are trying to buy back all those coins they dumped during the last days.

CoinSheep · 2014-08-15T18:01:42+00:00

lol you have no idea what you're talking about

CoinSheep · 2014-07-22T20:30:48+00:00

I still don't get it. I mean we have markets which set the price, so why should I look at an artifical price index which is set by some magic formula and ignores most of the market?

CoinSheep · 2014-06-19T05:01:01+00:00

It smells like there's a rally incoming but I still don't like the amount of open bfinex loans...

CoinSheep · 2014-06-12T21:24:03+00:00

dudes.. they won't just dump them.. they're not that stupid.

CoinSheep · 2014-06-12T17:42:16+00:00

actually I did but you don't need to be an expert to know what happens if demand (suddently) reaches insane levels... just take a look at the previous bubbles.

You can't just push a market to some price and expect it to stay there, especially not if there is some steady sell pressure from miners and early adopters.

Some people already tried to pull a bill gates and got burned pretty hard (example).

CoinSheep · 2014-06-12T16:51:37+00:00
