Probably because the CampBX Market ticker is not very useful and does not contain any volume data, causing a NullPointerException.



Don't know what could be causing this. You seem to be the only one reporting this. After you have completed the interview process and while AidoATP is running can you check the contents of your ~/.java/.userPrefs/org/aido/atp/ directory and see if it contains a prefs.xml file.

I'm trying to get ATP going in my virtual machine running Fedora 18.  Pretty sure everything is there it should need (verified I have 1.7.0 version of Java installed at least).  It starts up and gets the basic data of my CampBX account (wallet amounts, etc), but it dies with an exception when it starts trying to get the ticker data.  Here's the error:


It's also a bit annoying as it never seems to save the config either.  I have to go through the interview every time I start it up.  I'm not trying to do anything beyond simulation mode for now (want to see what my strategy does for a couple days).

Any ideas?

sorry for the Slow Reply

yes I got adioATP working on a mac

you can install 1.7  from oracle

but the only problem I had was saving the configuration
maybe its just the case of manually making the directory forthe pref file to be saved in

help that helps

agreed. Have been busy all this week but may get some time over weekend to look at the issues raised in this and other thread.

The github issue tracker is a good place to raise them.

Interesting.  I think we should maybe get an issue tracker up.  I'm not at a place where I have reliable internet for a few more days, but it would be a good idea to get one up very soon.

The ticker kept crashing for those currency/exchange combos so I disabled them with view to fixing at a later date. I don' think the error lies with ATP though. From what I can remember BigMoney was throwing an error.

Uhh what issue?

LTC is currently not supported. Neither is NMC, PPC, TRC and NVC. aidoATP does not gather any data for these currencies. XChange does not support these currencies, or at least did not when I put the following if statement in AccountManger:


(There was also an issue with CAD and INR on BitcoinCentral)
         

hmm I'm still getting the same error so it's obviously not working.  In theory it should though as LTC is just another currency to trade BTC in/out of.  For the purpose of testing I think I'll pull my LTC out for now.  If you figure out why it wouldn't create the LTC ticker data then give me a buzz!

Congrats, you're using a completely untested configuration.  I would love to know how it works out though.  Frankly I had no idea it could do that.

Thanks again for the feedback.  I'm trialling this with MTGox (BTC, USD, EUR, AUD, GBP) and BTC-e (BTC, LTC).  It's been running for a couple of hours now and I'm getting "No LTC ticker data collected yet, cannot calculate profit/loss" and I don't have a BTC-e_LTC.dat file.  Is BTC to LTC supported?

I have approx 1BTC at MTGox (split between various currencies) and the same at BTC-e split between BTC/USD/LTC.  I'll post a report daily of how it tracks (unless you would prefer I posted it in a different thread)

Unless you are prescient and can predict the market direction you should put at least a little money into each currency you wish to exchange.
Not all market movements are equal and it won't trade at all even if it detects a huge opportunity if there is no money to trade with.
Also many times an upward swing in 1 currency is due to a downward swing in another, but these are never 1:1 at least not right away.  The vwap trader can profit from both sides of this.

For instance...

I had (at one time) 100 BTC.
At the time BTC was trading at ~10USD.
                                           ~7GBP
                                           ~9.8EUR

I kept 50 BTC and split the rest into roughly even amounts of USD, GBP & EUR.

USD rate fell to $8, so it bought BTC with USD.
A few moments later GBP took a jump to 8.  Thus it sold BTC for GBP.
EUR rate also jumped to 10 so it sold BTC for EUR.

This all happened over the course of 5 to 10 minutes.
I let it run for about a day.

After 24 hours I shut the trader down and swept everything to BTC with a few market orders.  I had made 24BTC in 24 hours.  However the USD rate was back to 10.
The net effect was it had been running arbitrage although not because of any particular arbitrage opportunities it had identified, just a side effect of vwapping 3 markets simultaneously.  If I recall correctly this was the inspiration behind creating a pure arbitrage trader (which actually doesn't work as expected), but it was the inspiration for it.

So my recommendation is to trade a wallet of currencies you are interested in and that move with each-other;  It opens opportunities you otherwise would not have.
I am also recommending everyone start with a fixed amount of money and sweep out  any daily profits into BTC and then BTC xfr to your own private cold storage wallet.
Only sweep if you have end of day profits though.  Remember this is money you have said you don't mind losing.  Every day you will make a loss or a profit, but over the course of a few months you should see that gains will outstrip losses by about 5-10% regardless of the net direction of the market as a whole.

In the next version I expect to create a built in wallet not tied to MtGox that will sweep profits as they occur.

Depends on which way the market is trending. It first decides whether to buy or sell. Then it looks at the wallet balance to see how much to trade. If there are no funds available it will not trade. For example, if it decides to buy BTC but you have no dollars then nothing happens. But, if in the future the market changes direction it will then sell your BTC for dollars. You will now have dollars in your wallet if the market changes direction yet again and we decides to buy BTC again.

Actually one other question for you.  Should you begin with both a BTC and USD balance or will it pick an entry point to buy/sell depending on what funds you have?  If it is the former, what sort of split? 50:50?

Thanks I'm running Aido's version in sim at the moment so will report back my findings.  I'll try it for 5-7 days and then maybe throw a couple of BTC at it to see what it can do. 

Question: would you recommend using the trend following or custom bid/ask logic?

Cool, thanks for the explanation. and sorry for mis-filing the post. I have about 5 tabs of ATP discussion threads open and it looks like i didn't keep it straight.

I know just enough java to try to look for those multi-catch statements. maybe the code can be 'devolved' back to 1.6 (or i can get 1.7 running)

I now remember why I decided to use Java 1.7.

Before forking IsisATP to AidoATP I had never programmed in Java before. So, I was just playing around with a few things, trying to learn. One of the things I experimented with was the proposed Java 7 Elvis operator "?". As it turned out the proposal was never accepted into Java 7 so my playing around with it failed. I just decided to keep building with Java 7 and used one of its new features, multi-catch statements, in 3 places.

Basically AidoATP has no real reason for using Java 1.7 over Java 1.6.

Hi mccoyspace,

For some reason I can't remember now when I forked the original isisATP to aidoATP I decided to use Java 1.7.  I'm not a Mac person but I believe Java 1.7 is not available on Mac OS X. Although Ianwhitbread has reported that he has aidoATP running on a Mac using Java 1.7. I'm not sure what version of OS he is running.

Currently aidoATP source code will not build with < Java 1.7. However, with a few minor changes I think aidoATP can be modified to be built with Java 1.6. When Nova raised this issue in the other thread I did a quick check. A simple change to 3 or maybe 4 lines of code is all that is needed.

I was trying to use this thread for discussion on future development of ATP and issues like deciding on a suitable name etc. And use the other IsisATP and AidoATP thread for issues with the existing versions.....like this issue  .

Hello,
trying to run Aido, but I get this:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/aido/atp/Application : Unsupported major.minor version 51.0

java -version gives me this:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06-451-11M4406)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01-451, mixed mode)


on a mac 10.7.5 with the latest java d/l'ed from oracle.

I'm guessing is wants 1.6.0_51? and I've got _45.....

(btw, the old version of Isis started up no problem)

Yes it is, it's an open source project.  Aido's version is on github under Aido and the OpenPay one is on github under OpenPay/ATP although I'm having difficulty getting a commit to my own repo work right now (Probably because I removed my basis version (Isis-ATP) and then forked Aido's updated version into my own repo).  Use Aido's for the time being, they're basically identical at this point.  Just make sure to disable the Arbitrage Trader because it has some major issues.

Also, pro-tip don't trust it with money you can't afford to lose.  I had a thread lock the other day and when I resolved it in the debugger I was flooded with a bunch of buy & sell market orders that essentially wiped my position out because they had been piling up for a few hours.  I'm actually going to have to buy more bitcoins just so I can keep testing.
