change the end point to data.mtgox.com/api
this code is no longer working for me, but it was for a long time... is anyone else using the API with this code?
did gox make changes to their API to prevent DDOS/HFT?

while that is true, i laid out what i want in pseudocode pretty clearly and i also tried to make clear exactly how i want the spread to be calculated.
the last couple of things (including two programming tasks) i had made for bounties worked out pretty well.
the biggest problem is members with a limited understanding of the english language just diving head-in and doing *something* instead of asking first.
i dont want a moneymaking monster... i just need to sell close to VWAP, shouldnt be too hard.

bounty is 5 BTC.
Software for bounty is a great way to get low quality software from inexperienced devs who can't do any better. Not the greatest idea for automated financial software.
also tipped the member 4 BTC for his troubles.
so it turns out that one member quit because i obviously didnt make it clear enough what i wanted and how i want it.
so, any takers?
i will provide ftp access to my server so you can test it.
i will also provide you with my API credentials (with the necessary permissions and very few BTC) so you can make sure it really does what it should.
the tricky point was the spread calculation, it seems.

so say you go to
http://bitcoin.clarkmoody.com/
and you look at the column "sum"
i want the bot to use the bid order as bid side of the spread where "sum > x"
since this is the price where I can trade X bitcoins.

yes....
the one member i have workin on it seems very confident he will be able to deliver by monday.
i do, however, still accept submissions. the first (other than the member workin on it) to submit a working (!) bot for both sites receives a bounty.
bounty is 5 BTC.

are you still looking for people? I thought you said you had a guy working on it already and was almost done?
...
okay, one member of the forums is working on this and almost has it finished, but if you want to go ahead and send me your ideas, that's cool - if you send me a working php script then the 5 BTC bounty is yours.
this has no influence on the reward fow user gweedo, who is already nearly done.
I want to call this script via cron to sell my BTC if I should need to.
This is what it should do, this pseudocode SHOULD be understandeable, please post general questions in this thread.

Does it NEED to be in PHP? I can build one in Ruby for 200 BTC
Sure you just don't want a car instead?

already have someone working on it.
how much would you want for your bot and what are the features?
how much would you want for your bot and what are the features?
thinking about it, it should support mtgox (€ only) too.
it should be in a php file that i can call via cron every x minutes.
simple algo:
think that should be doable for a reasonable amount of BTC.
any takers?[/list]
it should be in a php file that i can call via cron every x minutes.
simple algo:
- calculate spread (bid and ask should be where X bitcoins are tradeable cumulatively, so I can ignore the 0.14471 and 0.4675 BTC orders)
- check "is there BTC balance in the account"
- yes --> create sell order for 1% of balance, put it in midspread
- no --> cancel all orders
think that should be doable for a reasonable amount of BTC.
any takers?[/list]
What would you like it to do?
i need a very simple intersango bot, preferrably on php basis which i can run from my webserver.
this is what it needs to do in my own little pseudocode.
