Upcoming changes in our margin trading feature July 12, 2014

In an ongoing effort to provide our customers with the best possible trading experience, we are pleased to announce several enhancements to our swaps system. As the swaps market continues to grow, we continue to be extremely focused on ensuring that it operates as fairly and efficiently as possible, while mitigating systematic risks to the greatest extent possible.

Self Funding: To the extent that a trading wallet’s collateral is the correct currency, it will now be automatically used to offset the position’s swap requirements. For example, if a trading wallet contains USD, and the position is long BTCUSD, the USD borrowing requirement will be reduced by the amount of USD collateral. We believe that this change will result in significant cost savings to traders and help make the closely watched aggregate swap statistics more meaningful. This new feature essentially allows traders to pay no swap interest when the positions size is less than their collateral, i.e., “unlevered” (provided, of course that the collateral is held in the correct currency), and avoids the clumsy process of claiming unlevered position as this feature effectively enables traders to perform the economic equivalent of a “partial claim” when the position is reduced in size of more of the correct collateral is deposited in the trading wallet.

Daily Settlement: Up until now, swap interest to liquidity providers has always been paid daily, but swap interest from traders is only collected when the positions is closed. While this makes sense from a certain perspective, it has the unintended consequence of effectively putting Bitfinex in the position of making 0% loans to cover the payments imbalance created by large “unrealized swap” balances, which really should be serviced by the P2P facility that we already have in place. Moreover, from a balance sheet perspective, we feel that it simply makes more sense to match the frequency of the collection and payment process. In order to implement this change, traders will need to select how they wish these daily payment to be made. The system will support a new variable for each position, “Swap Type”, which can have one of two values:

  • Daily (default): Swap interest will be automatically deducted from the collateral in trading wallet of a daily basis. If the correct currency is not present, an appropriate conversion will be performed to satisfy the payment.
  • Term: Swap interest will be capitalized in to position every night by automatically accessing swap offers to cover the required payment.

Existing positions will be phased into this process, with daily “catch-up” payments of no more than 10,000 USD.

These first changes will be active on the 21st of July, 2014.

Real-time Autorenew: In the past, the “autorenew” feature for offering swap liquidity was only processed once every 15 minutes, which could sometimes create an offer “vacuum” if large positions were being opened and closed quickly during periods of heightened volatility. We have reduced that interval to less than one minute as we approach a true real-time solution to this important feature.

Swap “Bot”: We will soon be offering traders the ability to automatically replace the swaps that fund their positions with cheaper ones should they be available at the same or better terms, eliminating the rather laborious manual process that is available today. There are many nuances to making this work efficiently and it will be offered on an “opt in” basis, but we anticipate that this feature will make the swap market much more efficient and reduce volatility in the average swap rates. We will provide further updates on the specific functionality by the end of July.

Once again, we wish to thank all of our customers for their continued loyalty, which, in recent months, has made Bitfinex the number one platform for BTCUSD liquidity as measure by trailing 30 day volume. We look forward to serving the community’s ongoing trading needs as we continue to update and improve our trading platform. As always, we welcome your feedback.

New fee schedule for LTC and DRK pairs June 05, 2014

In order to further increase the quality of your trading experience we decided the following

Fees on the LTC/USD, LTC/BTC and DRK/BTC DRK/USD pairs will be taken to 0.1% for market takers and to 0% for market makers. Adding liquidity to our orderbook will then originate trades free of charge. This plan will be kept in place until further notice

We hope you will appreciate this and we wish you a great trading day

DRKUSD and DRKBTC pairs added on Bitfinex June 02, 2014

We are pleased to announce that Darkcoin will be available to trade on the Bitfinex platform starting at 6PM CET. It is rare for us to add new trading products, but we believe that the advent of privacy-centric cryptocurrencies warrants our attention. Specifically, we believe that Darkcoin and the team behind it represent the most credible foray into this important frontier, and now that Darkcoin's market capitalization has reached non-trivial levels, we have decided to offer it as a trading option to our customers. As one might expect, will support trading in DRK/BTC, but, in addition, we will the first exchange to support trading in DRK/USD.

While we have no crystal balls at Bitfinex, we do nonetheless believe that the new features that Darkcoin aims to implement represents a substantial development in the cryptocurrency space, and we believe that any innovation that enhances privacy deserves our attention. Naturally, we do not condone the use of Darkcoin for illicit purposes, but we do believe in the right to privacy.

Initially, we will only offer cash exchange transactions. In time, as our order book deepens and Darkcoin successfully navigates certain milestones, we will also possibly allow swap leverage and shorting, should Darkcoin's risk profile and volatility merit it.

Darkcoins can't also be used as collateral for margin transactions.

We hope that you that you find these new trading products to be of value to you and we, of course, always welcome your feedback.

Introducing OCO orders March 18, 2014

As you may have noticed, we recently introduced a new feature: One-Cancels-the-Other orders (OCO orders). This feature will allow you to place both a take-profit and stop-loss target for your margin position without having to manually manage your orders when one is executed.

To take the most out of it, here is how it works on our platform:

To place an OCO orders pair, you have to chose a LIMIT order price (buy or sell) and check the option 'OCO'. A new field will appear, allowing you to set the stop price of the order pair. You can then place the orders pair by clicking on MARGIN BUY or MARGIN SELL.

When one of the order is AT LEAST partially executed, the other one will be cancelled automatically.

Happy trading
