May 16, at Andrew Barisser is a software and cryptocurrency engineer at Assembly. Previously he was a grad student in biophysics at UCSB, where he says a "gnawing fascination" with bitcoin led him to software. The experience has been fascinating, both on a technical level, and in a strategic sense. Writing logic that controls money itself is a strange thing. Setting it loose for the first time, knowing that any bug could literally throw away cash, was terrifying.

Bitcoin is an incredibly open system that is particularly friendly to no-name developers. The exchanges are already rife with trading bots; these are shark infested waters. Bots dance around each other in a chaotic swirl.

They employ so many diverse strategies. Entering into this environment, I had to be immediately cognizant of other bots.

Algorithmic traders need to occupy a particular niche. They profit from market inefficiencies. In a perfect market, what they do would not be profitable. In rectifying the little mistakes, the little instances of slippage that occur in markets, one may eke out small profits.

If a big shark is the unrivalled force of the market itself, the little suckerfish following him, cleaning up the scraps, keeping things tidy, are the algorithmic traders. They too have their place. To a small extent, explaining my strategy would be an invitation to competitors, for whom the marginal cost of setting up the software is very low. If you could always predict its every step, you could trick it into giving up money again and again.

This is something else that keeps my paranoia alive, the fear that someone out there will observe my bot, and in the to and fro of its orders, figure out its strategy. I imagine myself coming back to my bot, seeing its balance empty, because some mastermind gamed it algorithmically, draining pennies with each cycle.

It is basically a sophisticated market maker. It provides liquidity to the Coinbase exchange. This means that it looks at the order book and observes where the orders are thin. Perhaps there is very little order depth on the buy side.

It can place limit orders, like little traps, at varying depths on the buy and sell sides. It varies the exact way it does this based on recent market conditions. If a large trade is then suddenly executed, it may overwhelm the availability of offers at the best price. Such a large offer may then trigger one of my offers, lying in wait, at a more advantageous price. This is market-making Market-making also delivers real social utility. The deeper the liquidity provided by market makers, the more difficult it is to cause erratic spikes in price.

Other bots employ widely varying strategies. Some rectify the spread between separate exchanges, a strategy completely dependent on speed. If someone drops 1, BTC on Bitfinexthe price on Coinbase plunges in synchrony because someone raced to execute a market order. Other strategies revolve around tricking other bots, for which there are endless tactics.

Still others are designed to intimidate human beings with massive buy or sell orders. On a practical level, my bot must be very quick. If it is delayed even by a few seconds between cancelling and placing orders, market conditions can cause the new orders to become inappropriate.

The orders I place follow a sound logic assuming that the bot parrondo paradox forex a correct understanding of the state of the order book. This assumption does not hold for long.

I must also be on the lookout for hostile bots, who may place and quickly remove large orders with the intention of tricking other bots. The faster my bot can maintain awareness of the order book, the less susceptible it will be to such tactics.

My bot even has additional logic to prevent it from being tricked by fake volume walls from other bots. Similarly, Coinbase lacks an endpoint for creating multiple orders at once. So I must courses on binary options in novosibirsk multiple requests simultaneously.

A synchronous solution would take several seconds, which is far too long. Even a fraction of a second can be hopelessly long. It is on this scale that I still see my bot cryptsy trading strategies dumb and slow. It streams a websocket feed of new orders.

This process is also parallelized. So my bot mainly provides liquidity. It earns a small but steady amount from this. It holds roughly equal amounts of bitcoins and dollars, so abrupt price changes can leave it with losses forex headlines canadian dollar rate a given denomination.

My bot performs best when volume is high, but price swings are low. As a provider of liquidity, it smoothes the erratic undulations that would otherwise occur without market makers. In this it is providing a useful function, thus high volume periods are the most lucrative.

In some cases, sharp swings, back and forth, can cause my bot to persist in holding the wrong asset. Thus it is possible to lose money. My bot seeks to estimate the trading rate and moderate the depth of its orders accordingly.

This limits the risk of being caught in large swings, at the cost of having its orders executed less often.

As the price oscillates, my bot periodically loses money. The law of large numbers only works … over longer timescales.

One of the biggest problems with bitcoin is the way it is traded. The illiquidity of exchanges is a huge problem.

Compare bitcoin trading to that of any real financial asset, and you become forex broker uk observe a world of difference. Financial folks extract tremendous value in the maintenance of efficient markets in other assets. This does not just happen magically. Bitcoin needs better functioning markets if it is to attract serious players. Even at current trading volumes, a lot of value can be captured by smoothing out market fluctuations.

If bitcoin were to grow, the need for liquidity would also increase. The mere fact that I could dabble in this, as nobody, illustrates the wonderful openness of bitcoin.
