It's fixed! That was painful. Due to a change in the bittrex API the currency pairs wouldn't load anymore on OS X if we built leonArdo using Qt 5.5. Using the newest version of Qt resolved the issue.

Yes. Sorry about that, but there is an issue with Bittrex on OS X. We are looking into it.

For anyone out there looking for an automatic trading bot, please consider leonArdo! It comes with two strategies: a static ping pong bot and a dynamic mArgin maker bot that can adapt to the course. Plus you get historical data, orders (completed and active) visualised in the chart, the ability to drag and drop orders, indicators (MACD, Bollinger bands, EMA, SMA, VWAP etc.) and lots more features...

It's cost is fixed at just $89   (today that means just 0.12BTC)

We think it's the best bitcoin trading terminal on the market, but please don't take our word for it.

Here are some people who also think leonArdo is pretty cool:

leonArdo: a review by an unsophisticated trader

Don't hesitate to ask here or by pm if you have any questions we can help you with!

Download a free demo that let's you practice trading and get used to our bots here: leonArdo website

All the best,
The leonArdo guys

Thanks.

It's closed source as we have to try to make a living!

But other than downloading historical data from our servers to make beautiful charts, leonArdo connects directly to the exchange itself. To protect our IP we only hold half of one of your 2 API keys in hashed format.

Sorry for the delay with the new release. It will of course be a free upgrade for all existing customers though!

Thanks!

Thanks a lot dan_and_shan!!

You can test it out by downloading our free demo.

That warms the cockles of my heart to hear

Hey dan_and_shan,

Really glad you are loving leonArdo!

However, you shouldn't be having the issues you are. A bot is usually suspended when the network connection goes down or after a laptop is woken from sleep. For shorten network outages leonArdo recovers automatically, but for longer periods a bot will be placed in a suspended mode and will await manual re-start from the user.

If you notice strange behaviour not fitting the pattern I outlined above, which is normal, then please send us the logs for the affected pairs (logs are in the .leonArdo in your home directory) along with anything else that could help us e.g. screenshot & description.

Arbitrage is something that we have on our roadmap, but we are not currently working on it.

As soon as we release a new version the leonArdo login screen will let you know there is an available update. All you have to do is click on that link and you will be taken to the downloads page.

All the best,
Jonathan

Thanks a lot for the offer! If something suitable comes up I'll give you a shout!

Hi there,

I think you just bought leonArdo so welcome and thanks for your confidence and support!

The best way to get started is to check out the tutorial videos on our website: http://www.marginsoftware.de/tutorial.html

You can set the main parameters of the bot by interacting with it directly in the chart!

All the best,
Jonathan

The release is delayed because of the opportunity I cannot discuss right now, except to say we are looking to raise investment.

Thanks for your offer. Right now we are not hiring, but that could change soon

All the best,
The leonArdo guys

The reason you couldn't log in is that it is a paper trading version of leonArdo!

You need to choose one of the demo markets and then you can check out all the features in leonArdo. Practice running our in-built automatic trading strategies etc.

Let me know if you have any questions.

Best wishes,
Jonathan

Hmmm, ZEC wasn't in our data collection as it's new. Have added it now. There can be issues in the current version of leonArdo with new pairs not added. That will be fixed in the update that's coming - I promise! Thanks for checking out leonArdo!

You get an invalid range if you do not have the minimum tradable amount which is set by the exchange itself - not leonArdo!

Hmmm, I don't have Win 10, but I asked one of the guys to check it out.

leonArdo isn't going anywhere

Apologies to everyone waiting on the 3.0 release.

We have been delayed because of an investment opportunity. That has meant that all the last small bugs that needed ironing out were put on hold as we explore this great opportunity. We hope to get back to the release by the end of the week and it should follow shortly thereafter.

Thanks for your support and your patience.

Jonathan

Yes, leonArdo will show you the effective gain - the gain after trading fees are subtracted - and you can set up the bot and start it trading.

However, note that we have two bots. The static ping pong bot will simply buy and sell at the initial fixed prices you set them up with, whereas the mArgin maker bot is more dynamic. It adapts the buy and sell prices based on the amount of history you set it up to look at. You can tell it to always make a profit of 1.0% if you like, but it is also possible that it will make a higher profit if markets conditions allow it.

See my comment above as to why you might want to set a negative Min. Effective Gain.

All the best,
Jonathan
