What values do you run it at?
Always seems to buy low and sell high for me... but it did catch the more major dips so far which is handy

Been running it for a few days, tweaking it ever so slightly and watching the results.

One thing I've noticed is a profit calculation hasn't been shown afaik for me in the time I've been running the bot in simulation mode.

Any known reason for this I've missed.

"cold, hard PayPal dollars"

"eye-watering £17 transaction fee my bank demands for transferring a few bits of data across the English Channel"
^ haha! This is what bitbargain is for and transactionwise before that, and CurrencyFair too. It's a good point but we can't fix the banks... we're working on the pressure on them though, PingIt coming out after Bitcoin, lucky coincidence.

I think it is important to allow people to post competition in other people's threads.
Such free speech and free competition is exactly the sort if thing that enourages the market to be efficient.

It's a brilliant micro case study as to why people should be allowed to do things that are considered rude.
Another example would be standing outside a shop and poaching customers. It appears unfair but actually it is fair if the shop is free to do the same thing back to the poachers.

Being liberal on this is more efficient as it requires no action.
Being liberal also encourages the price to come down, better for consumers. And finally, it's a more efficient market.

In my culture I think it's rude but anglophone countries are particularly territorial and the UK is particularly territorial too. You wouldn't get the same opinion in Romania and probably many other countries (China) so you have to bear that in mind. They would say it's fair game.... no wonder those countries are on the way up.

edit: of course the disadvantage of a separate thread is that people are less likely to find that separate thread so it's worse for the consumer to have that and better to have a free-for-all.
Speak to a shop owner and he might say he's in favor of liberal business... but start poaching customers and all of a sudden capitalism seems to be a bad thing. That's the problem with people, it's all good when it's going there way but then when someone else starts doing the same they want special dispensations.

There's also these:

http://www.cxss.org.uk/drupal51/node/18

of which the easiest solution with support (in particular for arranging people, rather than just the tech) is:

http://www.cxss.org.uk/drupal51/?q=node/10
and fees to help with that: http://www.letslinkuk.net/practice/online.htm

or self hosting that to save some cash. The advantage of that system is that there's someone there to help set it up, host it (if need be) and be there to help if it's needed.
The disadvantage is that unlike Cyclos it's extremely basic. I'm assured that records can be exported from that system at at later date if needed.
167  Other / Off-topic / Local currencies accounting system 2013? (OpenTransactions ready for use?) on: July 18, 2013, 09:04:30 AM
 Last time I looked at LETs accounting systems was a couple of years ago now. What's changed since?

 Ideally we're looking for a way for members to go online, check their balance and pay and be paid easily. I shouldn't need to go into too much detail as to why the idea is to use this rather than Bitcoin or cash other than to say that there is some firewalling to the market this way.

 Last I looked we were going to use Ripple but it was very different back then and I don't want that much ease of connectivity to other markets.

 So what I'm looking for is decentralised accounting.

 Would this be OpenTransactions? Is it stable yet? (edit, update: No, not ready according to the git site) Is it (very) easy to use for old people? How would we handle people who don't really use computers? If so, where would be best to host it? I could pay for a low end server and do it but I'd rather use someone else if possible.

As an alternative, in a simple way Ripple could be used for this couldn't it? Let's say I was treasurer, then everyone would have to trust me with their currency. The next problem would be that I can't change my password and I can't share the job. So I think Ripple is no good (yet?).

 Any solution has to be totally ready as an alternative, in a simple way Ripple could be used for this couldn't it? Let's say I was treasurer, then everyone would have to trust me with their currency. The next problem would be that I can't change my password and I can't share the job. So I think Ripple is no good (yet?). And with a slick interface. There can't be any java interface shernanagans for the users.  

 What about more established online accounting systems? The most important thing is that any data can be exported and migrated to any new system that comes out down the line. Could a group edited Google spreadsheet actually do this since we have such a simple system?

 At the moment they're using one guy who makes a note of everything manually on the phone.

edit:

Just found Cyclos... seems like the best yet?
There's also https://www.community-exchange.org/ but it looks centralised and not making use of cryptography as much as Cyclos.

171  Other / Alternate cryptocurrencies / Re: Bitcoin bridge - Ripple on: July 14, 2013, 02:10:27 AM
In reading this thread we've seen a few people who don't know what Ripple is, nor how it is different.

With Ripple you are trusting other people to pay you back. That is "Promise to pay the bearer" as printed on GBP notes and specifically advised against as a bad idea in the bible. It's an IOU but unlike a Hawala notebook it's digital. Howeverm here's the interesting bit: you can infer trust to someone you don't know via someone else. Thus, if there's someone on the forum yoiu don't know you might be able to get trust via that someone else.

This is good when people are paying their debts but if it goes wrong the debt default Ripple goes through the entire system.

The other good thing is that Ripple facilitates setting up an exchange through the gateways. However, it's not as easy for the average user IMHO.

Finally, the whole thing is glued together with XRP and that is dodgy.

Scam or not, you must at least be aware of all this stuff!
172  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: July 12, 2013, 11:44:49 PM
You can always manually send them after the arbitrage.

Yes of course, that's what I'd like to envisage... but how would you best do that t for a EUR/RUR buy signal? - and also bearing in mind getting funds to the various exchanges is often a problem too (btc-e?)
173  Economy / Trading Discussion / Re: ATP [Advanced Trading Platform] on: July 12, 2013, 04:32:19 PM
Let's say we have the message:

"Arbitrage Engine has detected an after fee profit opportunity of 123.15897301% on currency pair RUR/EUR on BTC-e"

How would one take best advantage of that?

Arbitrage code in develop branch is very much experimental and the message is not true. As part of testing I hardcoded a very high profit percentage to make sure a trade would take place regardless of the true value.

No worries, I'm not trading live (actually opened some empty new accounts just for testing). I do love it though, gives me some satisfaction seeing saying something even if it does give a worrying counter to another trade strategy elsewhere...

Couldn't see that hard coding commented in:
https://github.com/aido/AidoATP/blob/master/src/main/java/org/aido/atp/ArbitrageEngine.java
but then I don't do java and I could have missed it.

My question though, and this was aimed more at the traders here rather than programmers was more about how to trade manually to take advantage of an arbitrage situation in general and that was meant as an example primarily. I see a scenario earlier in this thread but the person is using the example of 2 people who are friends and trust each other.

One way I can see if we have a signal for RUR/USD would be to go to a forex broker and click buy on that. But really for arb I was thinking more about Bitcoin and then it gets complicated with transaction delays and costs in for example sending USD from Bitstamp to USD.

Of course, http://bitcoin-analytics.com/ does alot of it for us... but for a fee. There are also other arb bots... but I don't see how they work without sending funds from one exchange to the other

Thanks for your help. I've sent a ( tiny :/ ) tip as thanks.

My idea was to run Gekko on 2 different servers, then if one goes down the other will be doing the same thing anyway as backup.

 It seems Raspberian O/S nodejs is out of date. Debian on the other hand required compiling nodejs but that wasn't too bad. Gentoo was more straightforward

edit, found this:
Code:
terminate called after throwing an instance of 'std::bad_alloc'

It worked before. Queer.

I've been running it on a Raspberry Pi with Raspberian successfully... hmm, what's changed.... I had a external HDD fail but that wasn't the O/S and just data... did a reset... perhaps I had upgraded something which wasn't active until reboot...

I would guess that using npm -v 1.1.4 with mtgox-apiv2 would probably be ok... just searching for a way to bypass...

In the mean-time I'll try using a debian box to test as well... now compiling nodejs...
