  1. ella jewelry wholesale Bitcoin has been a hot topic in the past two or three years. Although the Cuckn sports team has not participated in the speculation of Bitcoin, Jason's good friend Roy in Berkeley is a good master. At the end of the European Cup, Jason is okay? It is easy to convince Roy and share his experience in Bitcoin arbitrage in the past few years.
    roy and Greyou Sports guarantee the story, but we are not responsible for losses for the inspiration of this story to conduct relevant investment speculative behaviors.
    (The following is the first person's narrative of ROY:)
    The attention Bitcoin was about 2011, when I met Michael, a high classmate in school at the school, Michael told me he spent 10,000 US dollars before. After buying 1,000 bitcoin, it has been earned 10 times. And talk about the significance of Bitcoin's shrinkage and inflation, and his investment opportunities for bullish Bitcoin.
    . My interest comes from the statistics of the data changes in Bitcoin, so I wrote some crawlers to catch data in my free time. When I climbed the data in the house, Roman came to me. Romance was very I like to trade myself, so I talked to him about Bitcoin. As a result, Roman was more powerful than me. After a few days, he called me and said that the price difference between the exchanges was too great. Why is there no arbitrage? I don't care about it, it may be caused by certain transactions. Therefore, the two of us began to study how arbitrage, and we also found that the price difference is so large:
    1. Most of the exchanges closed the registration due to legal issues;
    2. It takes 5 to 60 minutes between the two exchanges) (this time consumption is related to the principle of Bitcoin) -the price fluctuations during this period are enough to eliminate most of the profits;
    3. Between the U.S. exchanges, but the RMB control, which has caused funds to fail to return, and the liquidity between the market is poor.
    In response to these three issues, we came up with countermeasures at the time:
    1. Strive for finding a registered exchange. At that time, Bitcoin Exchange was more entered into Niu Mao, and there were always registered registered.
    2. If the price difference between the exchanges is large enough, it is not afraid of the fluctuations of these 5-60 minutes-a high probability that we will have a profit.
    3. There are many ways to find the exchange channel, which should be described as hopeful.
    So we entered the practical stage.
    The websites that could be bought directly in the dollar at the time, but there were many exchanges, the biggest is Bitcoin China (BTCCCHINA). We searched for a long time and found a website called Local BTC. Probably the idea is that you can book Bitcoin, and then after forming a potential transaction, the website will help you freeze some of the seller Bitcoin. After you transfer it, this part of Bitcoin will return to you. Essence It is equivalent to the Local BTC that has the function of Alipay.
    The first transaction we bought 0.94 Bitcoin, this number is too unforgettable. This single transaction made 30%, so happy. To solve the actual operation problem, we need to find a place where you can buy a large number of Bitcoin in the United States. Local BTC is all retailers, and the number is too small, and the largest exchanges in the United States, such as MT. GOX, have closed their registration. At this time, we found that the Canadian exchange Virt EX was likely to register, but to register a company. When we were going to register a company in Canada, we found that domestic Bitcoin players have madly squeezed the existing profit space. At that time, the Bitcoin price of the two places maintained at 30%-50%for a long time, so many domestic Bitcoin players with US-US exchanges bought a large number of Bitcoin. The US dollar (at that time the Sino -US exchange rate was already 6.2x), and continued his arbitrage, which quickly reduced the price difference between the two sides. We don't feel that we will not wait for our Canadian account profit space.
    Is when this incident was out of the way, our data told a turnaround. After careful analysis, I found that several exchanges of the renminbi: BTC China, Huobi.com, and OKCoin often have a large price difference, and three account opening is convenient. At the same time, domestic exchanges are the first to start providing the function of borrowing Bitcoin, which allows us to start imagining whether it can be arbitrage between RMB exchanges.
    So buy directly on the exchanges at low price, then transfer to the exchanges with high price, and then sell it? This looks simple, but you also need to bear the 5-60 minutes of transfer price fluctuations because you have no hedging.
    It Roman came up with a new arbitrage method. It is to buy and sell the same number of Bitcoin in the two different markets. Once the price difference is large, the same number of Bitcoin is sold and bought at the same time to complete the arbitrage. Then wait for the price difference between the two exchanges to narrow. But the core problem is that sometimes the price of the two exchanges will not really reverse. For example, the price of BTC China has a high price for a long time. What should I do at this time? At this time, you have to calculate the average level of the two sides, buy and sell when the price difference is floating. The process of buying and selling may be lost, but it is generally profitable.
    I assume that the average difference in the difference between the two exchanges is 100, but the stable shock is near this average, and you can do the corresponding positive and reverse buying and selling at Outliers. At this time, from a single transaction, it may be a loss, but from a transaction circuit, statistics are significantly profitable.
    At this step, this transaction is no longer a pure arbitrage, but a statistical arbitrage -we gamble the spread of the two markets to stabilize near a level, and the volatility of the spread is also stable. From the perspective of mathematics, the price of the two exchanges (P1 and P2) conforms to the following relationships:
    In the transaction method, we need to compile a trading system. This system has been developed for 3 weeks. The code of a person code, who had no chance to practice a trading system in the school before, had encountered many problems. At that time, the biggest difficulty at that time was that two exchanges were required to place orders on each exchange each time, but the number of transactions on both sides may be different, so that the order is required later. We have proposed two solutions:
    1. Linear order, first place the exchange of exchanges with fast price changes, get the exchanges with a slow change in order, follow the order of slow changes
    2. Single, and then check the risk exposure of the entire system each time, if it is not zero, it will be made up a single side -if you want to buy a Bitcoin, go to the low -cost exchange, and sell Bitcoin to high -priced exchanges.
    In the development of the trading system, soon we encountered new problems. The automatic login system was locked and the exchange set up a verification code. Fortunately, they have a mobile terminal, and we find that the mobile terminal has no verification code, so I set up from the mobile terminal to solve the problem.
    After all are ready, we start to trade. Of course, both strategies and systems have encountered quite a lot of details. Here we need to omit the process of debugging tens of thousands of words. As we keep adding positions and increased frequency, soon our single exchange's transaction volume reached an astronomical number:
    Although it looks scary, the profit of each transaction is very thin, and so The capacity of arbitrage is very limited, and it feels a bit to make money without making money. But one month later, we basically don't need to worry about it. What should we do? Just get up in the morning to collect small pocket money. From 0 to build a trading system, you can only understand if you experience it yourself.
    The end:
    The operation to February 2014. At that time, a major event occurred in the Bitcoin industry, that is, MT. GOX, headquartered in Japan, was closed, which brought about the price of Bitcoin around the world. Great volatility. After MT. GOX closed down, everyone once decreased with confidence in Bitcoin, and the transaction volume began to plummet after reaching its peak. Our profit space is getting smaller and smaller.
    The rumors of the central bank to restrict the withdrawal channel of the domestic bitcoin exchange, so that the funds will become more and more unsafe. So we decided to stop the transaction and find a job from new to normal life.
    Post -postship:
    In the automated transaction of the US interest rate market by myself, and I also met more and more friends who have made various "strange assets" arbitrage -including Diablo game props, online Texas poker, online Texas poker, Finding an interesting law:
    The more things (funding, technical, policy), the simpler the strategy, and the lower the threshold, the more complicated the strategy.
    The interest rates in the United States and domestic stock index futures are assets with low entry thresholds. Therefore, the design and tuning of trading strategies are relatively complicated, while Bitcoin and Diablo game props are The trading system requires a lot of effort, and the strategy in it is not complicated.
    Therefore, a arbitrage or transaction team needs to accurately estimate the capacity of input -output. Assume that your technical strength is strong, but the strategic ability is not strong, you can get more into the strange market of Bitcoin, and use technical power to smooth the ineffectiveness of the market; if the strategic ability is strong, you can do common assets of low -frequency frequency; If technology and strategy strengths are very strong, you can try high -frequency Alpha transactions with various active assets -this requires the perfect combination of technology and strategy -this is also the charming feature of high -frequency transactions. (End.)
