Thanks for your interest Jude!

We posted a new thread here: https://bitcointalk.org/index.php?topic=1078323.0 and in it are details on how to get your hands on a free demo paper trading version of leonArdo. Or you can just go to our website and download a copy. That means you can try it out before you have to decide whether to buy it!

Hey testbug,

sorry for the delay, but we are working on a new release and an announcement which is due soon.

Btc-e and Bitstamp are available right now. Bter and Poloniex are (partly) implemented and in internal testing phase.

If you want, your password is just kept in your local memory. If you do not want to enter it at each start up, you can store it in an encrypted container on your local harddisk.
This functionality is already integrated and is available with a click.
We just serve history data for convience. If that scares you you can just block the ip or we build a custom version for you, but it really is nice to use that data
The software talks directly to the exchange API.

sorry again, but we are quite busy right now. If you like we are also available for a skype call.
For more information just have a look at our webpage: http://marginsoftware.de
If our response time on the forums is slow just drop us a message at contact@marginsoftware.de ;-)

New leonArdo version available!

There is a new leonArdo version available for all existing users.

We also have made updating super easy. Just fire up leonArdo and you will see an update available! link on the login page. Simply
click on that link and you will be brought to our webpage where you can download the particular flavour of leonArdo (Windows, Mac or Linux)
you want.

There are some other minor stability and GUI improvements that we are sure you will like.

A big announcement coming from us in the next week or two. The fruits of our hard work will be revealed soon....

Hi SavellM,

It depends

If you use the Static Ping Pong strategy you set a buy and a sell price and these remain fixed. However, if you use the mArgin maker strategy, it has a Max. order age parameter you can set which determines lifetime of an order before it is replaced. Once this expires the strategy will take the current market statistics (including your chosen buy and sell margins) and place a new order. To control the amount of gain you want to achieve you can set the Minimum effective margin [%] parameter. E.g. setting it to 1.0% limits the strategy to only placing orders that will result in an effective gain (after the subtraction of exchange fees) of 1.0%.

Does that answer your question?

All the best
The leonArdo guys

Clearly not the right choice for us to spend time implementing support for bter given what has happened. Ah well, looks like bitfinex will be next for us now.

Hope you guys didn't get burned too badly...

We'll check this out. Thanks.

Thanks for your interest.

We are nearly finished with bter and bitfinex and will be releasing them soon. Bittrex is also on our radar, so stay tuned

Great idea. We'll get to work on it

leonArdo beta 1.4.0 released

We have been very busy improving leonArdo and all registered customers have received a link to the newest version!

Release notes

• Total restructuring of the mArgin maker strategy
    - Partial orders are handled explicitly now should an order need to be replaced due to max order age being reached
    - The Min. effective margin is now applied to sell/buy cycles and not only buy/sell cycles
    - In a market specific manner the minimum tradable amount is set to ensure the strategy can continue trading after the subtraction of fees
    - Logic has been improved
• leonArdo will automatically restart trading after a network outage now (no more coming back to a dialog waiting for your input )
• Notifications tab updated to allow entries to be stored in a client database. To remove notifications simply select all and click 'x'  or click the tick you if want them to remain but not show as a number in the notifications icon
• Improved display of numeric values for better readability. For example, hover over a value in the slider and the full precision will appear as a tooltip
• The "Total" label in the top left corner of the volume chart now also provides an estimate of the resulting volume in the other currency. For example: 2877.8 BTC [641.58k USD]
• When you hover your mouse in a within the depth-chart for more than 2 secs, an estimate of the resulting amount in the other currency is provided
• Some more changes under the hood
    - Improved thread safety when manually adapting strategy orders
    - Adapted internal handling of all price and amount values for more accuracy
    - Added new framework for faster integration of new markets (BTER and Bitfinex are already in the testing phase)
• several smaller bug-fixes

Best wishes,
The leonArdo guys

Really enjoying the P2P Financial Systems 2015 workshop in Frankfurt, Germany. A nice mix of Bankers and Cryptocurrency enthusiasts.

Andreas Antonopoulos gave a great talk this morning. If you are interested we are live twitting from the event (@mArginsoftware) and there is a live stream here: youtu.be/4uEhnTToqIc

Have you looked at leonArdo? -> http://marginsoftware.de/
We have written it from scratch in C++/Qt  and we use it mainly on Linux ourselves.
We support Bitstamp and btc-e already and are testing Bitfinex and Bter at the moment.

You can see it in action in this (a little bit outdated) video:
https://www.youtube.com/watch?v=bm1G_Vlzq9k

Give us a shout if you are interested, we are happy to answer any questions.
If not, let us know what you are missing

Some reviews from our users:

https://bitcointalk.org/index.php?topic=506317.msg9742805#msg9742805

P.S. If leonArdo does not fit you and you are fine with btc-e you could use their MT4 platform.
Other than that I don't know any solid client. Which was the reason why we build one our self.



Happy trading.

We have just released our new website. Check it our here:
