One Ethereum Trader Just Made $1,142,400 In Seconds, Thanks To An Epicglitch

One Ethereum Trader Just Made $1,142,400 In Seconds, Thanks To An Epicglitch

One Ethereum trader just made $1,142,400 in seconds, thanks to an epicglitch Yesterday, a market where people trade the Bitcoin-like cryptocurrency Ethereum crashed instantly. The value of Ether (the Ethereum currency) plunged from about US $300 to $0.10 in seconds. Then it bouncing right back up to $300. Heres how this extremely unlikely event unfolded: Around 12:30 pm PST the price of Ether which had been trading on the GDAX currency exchange at around $300 suddenly dropped to $0.10. The official explanation is that a trader placed a multi-million dollar order to sell Ether. In the chaos, computers sold off Ether in automated, price-triggered sell orders. Traders lost millions of dollars. But one trader had an automated buy order telling computers to buy 3,809 Ether if it ever dropped so low as $0.10. Within a few minutes, the price of Ether completely recovered to around $300. This meant that the 3,809 Ether the trader had just bought was now worth $1,142,700. The trader had made a 300,000% return within a few minutes. Weve had flash crashes like this before ( 2010s sudden Dow Jones price drop of 9% ). But nothing of this magnitude, where an asset lost 99.96% of its value in a matter of seconds. And in case youre wondering, no GDAX is not issuing refunds or reversing any of these trades. Heres their official explanation of what happened . Update from GDAX : We will establish a process to credit customer accounts which experienced a margin call or stop loss order executed on the GDAX ETH-USD order book as a direct result of the rapid price movement. All this leaves some lingering mysteries: Why did the price of ether crash so suddenly and so completely? Did someone intentionally manipulate the market with the multi-million dollar sell order? Why didnt GDAX have count Continue reading >>

Maintaining An Order Book On The Blockchain (part 1)

Maintaining An Order Book On The Blockchain (part 1)

Maintaining an Order Book on the Blockchain (Part 1) Introducing the price bitmap technique used to help match orders entirely on-chain In our first UbiTok.io blog post, Im going to introduce the technique weve developed to efficiently maintain an order book entirely on the Ethereum blockchain, including performing best execution matching. A limit order book is simply a set of open buy orders and a set of open sell orders. But to be useful, it needs to let us easily: see if a new order will match any existing orders on the opposite side, and remove the existing orders if it does; When matching orders, we want best execution - for example, if there is one open sell order at a price of 1.23 and another @ 1.24, if I put in a buy order at @1.25, my order should match the sell order @ 1.23 first. Now, if you were implementing a centralised exchange in a normal programming language, youd probably store each side of the book as an ordered map from price to the orders at that price. 1.23 => [ SELL 200 ]1.24 => [ SELL 100 ]1.30 => [ SELL 400, SELL 500 ] Behind the scenes, the ordered map would probably use a Tree - as Javas TreeMap does. On paper, trees are great - they let us cheaply add and remove entries, as well as walk through the entries in order of price starting from a given price. However, the Ethereum Virtual Machine is not a normal programming environment. In particular, reading from and writing to storage costs gas, which has to be paid by the user. This is fair enough - we have to compensate the Ethereum network for hosting our order book on thousands of computers. Sadly, in this environment a tree is a bad choice because theyre only cheap on average. The worst case behaviour can be quite bad - for example, some poor user who just wants to cancel her order could en Continue reading >>

Why The Gdax Ether Flash Crash Isnt Surprising, And What It Means Forcrypto

Why The Gdax Ether Flash Crash Isnt Surprising, And What It Means Forcrypto

Why the GDAX Ether Flash Crash Isnt Surprising, and What It Means forCrypto On Wednesday, the price of ether flash-crashed by over 99.9% in less than a second on GDAX, one of the largest cryptocurrency exchanges. This was due to a multi-million dollar sell order being placed on the exchange. Because the exchange did not have enough buy orders on its books to accommodate a sell this large, the price crashed immediately from $317.81 to $224.48; this movement was enough to then trigger a wave of about 800 automatic position liquidations due to margin calls and stop-loss orders, driving the price briefly as low as $0.10, and causing GDAX to suspend trading. This is only the most recent of a series of similar events across crypto exchanges , and rather than being a reflection on GDAX in particular, its a symptom of the underlying problems created by the stress of capital flow increasing faster than market infrastructure development. Although the price quickly returned back above $300, the millions of dollars that investors lost due to forced selling of their positions will not be recovered. This incident highlights the relative immaturity of the cryptocurrency trading ecosystem, which has been stressed by a 20x increase in daily trading volume since the start of 2017 without any fundamental change in market structures. From the trader-in-questions side (assuming they were simply trying to get out of this position in a crude way and not a malicious actor or market manipulator) dumping the whole position at once will have likely incurred millions in liquidity costs. A single huge move like this is both bad for them and for the margin traders who were forced out of positions at even worse prices, all due to price actions that would be easily avoidable through more intelligent Continue reading >>

Contract Development - Token Order Book In Solidity - Ethereum Stack Exchange

Contract Development - Token Order Book In Solidity - Ethereum Stack Exchange

Would the following work for making an order book for tokens (trading tokens for ether / tokens for tokens etc.)? When an order is placed, it is added to its respective struct array. The higher a buy/lower a sell order price is, the less gas it costs because less of the array has to be iterated through and modified (making it a more efficient market). Obviously I have to refine it more and reduce gas but is something like this feasible in practice (seems to work fine in testing)? Not sure if real implementation would breakdown with concurrent orders changing the state of the arrays. contract OrderBook { OrderStruct[] public buyOrderBook; OrderStruct[] public sellOrderBook; struct OrderStruct { uint price; uint quantity; address sender; } // Submit Buy Order function buy(uint _maxPrice, uint _amount) { while (_amount > 0) { if (_maxPrice >= sellOrderBook[sellOrderBook.length - 1].price) { // Match Orders // Delete Order From Sellbook // Adjust Sum } else { addBuyToBook(_maxPrice, _amount); } } } // Submit Buy Order function sell(uint _minPrice, uint _amount) { while (_amount > 0) { if (_minPrice >= buyOrderBook[buyOrderBook.length - 1].price) { // Match Orders // Delete Order From BuyBook // Adjust Sum } else { addSellToBook(_minPrice, _amount); } } } // Add Order Details to Buy Order Book // Place in correctly sorted position (ascending) function addBuyToBook(uint _maxPrice, uint _amount) private returns(bool success){ if (buyOrderBook.length == 0) { buyOrderBook.push(OrderStruct({ price: _maxPrice, quantity:_amount, sender: msg.sender})); return true; } uint iterLength = buyOrderBook.length - 1; for (uint i = 0; i <= iterLength; i++) { if (_maxPrice > buyOrderBook[iterLength - i].price) { if (i == 0) { buyOrderBook.push(OrderStruct({ price: _maxPrice, quantity:_amount Continue reading >>

10 Step Guide For Day Trading Bitcoin, Ethereum Andlitecoin

10 Step Guide For Day Trading Bitcoin, Ethereum Andlitecoin

10 Step Guide for Day Trading Bitcoin, Ethereum andLitecoin Ethereum is up over 2,000% since the start of2017. Bitcoin is one of the most important inventions in all of human history. For the first time ever, anyone can send or receive any amount of money with anyone else, anywhere on the planet, conveniently and without restriction. Its the dawn of a better, more freeworld. This past Labor Day weekend (Sept 2017), needing a break from my startup Harvey , I had the choice of binge watching Narcos 3 on Netflix or taking a deep dive into cryptocurrencies. Since learning about the impressive $100M fundraise by Coinbase at a $1.6B valuation last month, Ive been eager to understand their product suite a little better and discover where there might be a new income opportunities, so I jumped in and went deep. Disclaimer: I am not an expert in cryptocurrency day trading, nor do I pretend to be one. I am not offering financial advice. Please understand your own risk tolerance and be responsible with your hard-earned money. I started by wanting to know, in particular, if bitcoin was going to be the punchline of jokes like beanie babies in the 90s, and featured in Economics 101 classes as part of bubble theory. My quick conclusion: I dont believe the bitcoin hype is over-exaggerated. While there will be significant volatility in the price and valuation of bitcoin over the coming years, I strongly believe it and the entire asset class of cryptocurrencies will become a core part of the financial system within 3 years or less. There is enormous risk in trading these assetsmore so than gold, REITS and other commoditiesbut the global market capitalization of cryptocurrencies ( $148 billion today ) I expect to pass $1 trillion by 2019. Many of todays coins will die off, and the ones th Continue reading >>
