Many times two separate cryptocurrency exchanges have slightly different, or very different trading price bitcoin currency arbitrage maths the same pair of coins. New traders immediately have the idea that if only they could buy the low price, and sell on the other exchange for the high price bitcoin currency arbitrage maths would be immediate risk-free profit also known as an "arbitrage opportunity.
While the idea is solid, several undesirable effects hinder the average trader's ability to establish such an arbitrage in practice. This article explores possible solutions for these problems and introduces a bit of math which is required to make sensible judgments when arbitrages exist.
At some point during the day, you might notice that the Bitcoin currency arbitrage maths ASK price is lower than the Bitfinex BID price, and decide that this is an excellent opportunity to buy low bitcoin currency arbitrage maths sell high. Let's assume that the Poloniex wallet has been sent 1 BTC in advance. Then in some miraculous way, manage to transfer these ETH to Bitfinex.
Step 2 Sell "high" on Bitfinex. Several assumptions make this trade unrealistic. The first assumption is that there is a miraculous way to transfer funds from one exchange to the other, and another assumption that there are no fees involved.
In fact, there are no miracles when it comes to trading, so solutions for bitcoin currency arbitrage maths assumptions need to be explored. Option one is to withdraw from one exchange and transfer ETH into the second exchange.
Some newbies to crypto might think that they need to move coins first from Poloniex to their personal wallet, and then from there into Bitfinex. Seasoned traders can tell bitcoin currency arbitrage maths this is not true, there is a way to transfer funds from a wallet at Poloniex to Bitfinex directly and just save quite a lot of hassle.
But even with time saved, there are still withdrawal fees to take into account. According to Poloniex, withdrawing ETH incurs a fee of How much does it cost exactly using the higher ETH price? Here go 38, satoshis down the drain, leaving just 78, satoshis for our precious profit, a very hefty price to pay. And if that was not enough, then there is another severe problem with this method, it takes a long time - during this period the price at Bitfinex might no longer be the original price seen at the moment of the original signal, making this whole arbitrage business more of a speculation.
Speculation is hoping that the price will remain the same or rise a bit to maintain profits and it is not in the spirit of the original riskless and immediate arbitrage idea. Option two, bitcoin currency arbitrage maths some ETH sitting and waiting for opportunities at Bitfinex.
When an arbitrage is spotted - immediately trade using existing ETH liquidity, removing the requirement to transfer any funds from one exchange to another. It does require to hold some ETH cash on bitcoin currency arbitrage maths selling side. Bitcoin currency arbitrage maths, after multiple arbitrage executions, more ETH accumulates on Poloniex where the buy trades occur, and less ETH on Bitfinex where it is regularly being sold for profit.
Maybe eventually there will even be zero ETH remaining on Bitfinex since it was all used up in trades while a whole bunch on Poloniex where cheap buys were happening. This second bitcoin currency arbitrage maths means that there is always some ETH that needs to be liquid on the exchange where sell trades occur. There is no way of knowing where such sell and buy opportunities will appear, so it is a good idea to keep ETH on both exchanges and just wait for signals - hopefully, the signal to sell high will be coming from a different exchange each time, or at least some of the times.
I call this "The Pendulum," the balance of ETH is seamlessly moving from one exchange to another back and forth.
Bitcoin currency arbitrage maths more actual transfers of ETH are required, saving the time and transfer fees. But the bitcoin currency arbitrage maths amount of ETH across all exchanges better be preserved, or we end up with no liquidity to arbitrage anymore. The seasoned traders among you have been yelling for the last couple of paragraphs: You must not forget the trading fees!!! Let's calculate what effect these have on the profit of our fantastic arbitrage opportunity.
Well, since the arbitrage needs to happen "Right Now! Limit orders are not executed immediately but only when someone else takes the assigned offer. Since predicting the direction of price movements is speculation and not arbitrage. In arbitrage, trades need to happen simultaneously on both exchanges at once and cannot sit there in the order book hoping that the price will "go our way" since it probably will not.
Oh no, when fees are applied the loss issatoshis! This number is three times higher than the profit calculated in the first step. But it is a loss, not profit! Here is when veterans casually throw bitcoin currency arbitrage maths a warning to naive new traders who think that exchanges are dumb and money is just lying there on the table for the taking.
If only the price difference were larger, then there must be a profitable opportunity in there somewhere right? We just chose a non-profitable arbitrage, but bitcoin currency arbitrage maths there are many profitable ones. Which is why I want to introduce our friend, Math. Using simple math, there are just a couple of calculations that show how bitcoin currency arbitrage maths discover such arbitrage profit and learn its exact value.
The total balance across all exchanges of ETH needs to be kept at a fixed value leaving the profits in BTC while maintaining liquidity of ETH for future arbitrage opportunities. The result is the same number of lost satoshis as before, which suggests that the math is most likely correct.
When selling price reduced by both fees is higher than buying price, it's a profitable arbitrage opportunity. Done, for bitcoin currency arbitrage maths, hope you liked this short break-down of an arbitrage trade. More aspects not touched in this article, like the depth of order books available, liquidity balance at each exchange, how to rebalance liquidity, leveraged trades, ask-ask and bid-bid arbitrages and much more must be left for future articles.
Feel free to try our bitcoin currency arbitrage maths system at http: Oh man, thanks for this. I don't really want to try my hand at arbitrage, but I'm nonetheless interested in how it might or might not work, and this is a great overview. There are plenty of "arbitrage calculators" out there, but they aren't very useful because they're overly simplistic. Do you know of any automated bot software that can do this automatically.
I wrote my own software using existing API libraries. Only tested on a limited amount of exchanges and coin pairs, and could not find any profitability when fees are taken into account. Although arbitrage probably does exist, it not not a regular occurrence and in my limited experience not something that can be traded hundreds of times every day. It can be profitable if you work with exchanges across continents. For example, I buy litecoin on coinexchange and sell it on altcointrader. The margins are greater as you're selling in local currency which far weaker than the US dollar.
Why are you using arbitrage examples with only a. I can spot endless examples times more than that. You just need to know when and where and be alerted when the conditions exist.
The arbitrage spread is much larger than your math suggests and I took this screenshot just 2 days ago. The issue with BTC Spreads is transaction time. If you send BTC from one exchange to the other, most require at least a 6 block confirmation as of this morning that time sits at around 9 minutes.
A lot of volatility can change in the hour that will take. If the transfer was instant, or you had a fast intermediary currency you may be able to beat the spread, but even a dollar difference in bitcoin is only 2. So you need to be able to beat the fees, and hope that the exchanges don't catch up to each other within an hour.
Otherwise you lose out on the fee portion instead of materializing a gain. However, I can't seem to open an bitfinex account anymore. Your post was insightful and I certainly would like to read about other aspects bitcoin currency arbitrage maths touched.
About 3 hours later and no arbitrage opportunity any more I realized it was not as "easy" as I thought it was! Great arbitrage opportunity https: It would be great to read your thoughts on how to take into account depth of order books at the time of arbitrage trade and regarding ask-ask and bid-bid arbitrages. I love arbitrage situations, as it usually means someone messed up somewhere and you get to 'stick it to the man': It worked really well in the old days when you could do a triangle of currencies, but the internet and instant quotes kinda killed all that.
The only place I can think of now that still offers arbitrage opportunities is sports betting sites, heard of a few people still making money from that while they can.
The math behind cross-exchange arbitrage trading steem Created with Sketch. Poloniex ASK price - 0. Step 2 Sell "high" on Bitfinex - To miraculously move funds, I suggest two possible options for consideration - Option one is to withdraw from one exchange and transfer ETH into the second exchange. The first option is out; let's see what else is there. The problem of moving ETH around is solved, but more assumptions to dispell remain - The seasoned traders among you have been yelling for the last couple of paragraphs: Poloniex taker fee - 0.
Let's do the math again, this time taking fees into account. Feel free to upvote to reward this content and share it with your friends. Authors get paid when people like you upvote their post. I would like to read the articles on the other subjects. Lesson definitely learned that night lol.
Nice article, upvoted and followed. Thanks for the informative post, was interesting. Can you share the link for the bot you built please?
