Topic: Open source trading bot? (Read 12490 times)

For low trading prices, trading on Open Transactions servers might work. They do not even have mechanism in place for taking a percentage of trades at all, the only support they have for fees really is "usage tokens" against which all API calls are charged.

On first glance it seems as if this should help for reasonably-sized trades, but hinder stragegies that want to make many API calls per trade.

I have not checked yet whether the API calls themselves are reasonably "priced" in terms of the usage tokens, such as whether one can get a huge mass of data in one API call instead of having to make one call per market or suchlike.

I have set up my Open Transactions server to use integers for all assets, deliberately to help encourage volume trades. (As to get three digits of price granularity you'd have to use 3 digits of scale, like "100 of this for 101 of that".)

On the other hand I am not a fan of high frequency trading, I have often thought of actually bundling all offers within a half hour or so into one batch clearing run that processes them all at once, specifically to keep bots from butting in between a matching pair of offers to grab most of the difference that otherwise would have gone to the up-front "honest traders" who admitted what they wanted instead of lurking in the background "sniping".

any chance of an update to that bot? it seems to detect the same buy and sell price

Nope, coded in lazy man's VB .Net. Windows only.

Everyone needs a bot.

This is for Linux?!

Thanks!

Tell me how this dark magic werkz!!!!!!

Your code looks pretty solid, I'll let you know if I run into any bugs, expect a donation within the near future.

great!

bug one: tried it with one (almost) empty account. i suddenly thaught i was rich! damn u {"usds":"0","btcs":"0.00037738"} is shown as: 37.738,0000 BTC

ask and ye shall receive.

added a simple buy and sell box to my bot.

check the box, place your values and when the ticker hits the specified points, it places a buy or sell order.

let me know what bugs you can find.

link in sig.

Is someone going to start a open-souce bot it a more cross-platform language. These open-source bots don't even need any algorithms. just.

if < 9.90 buy
if > 10.10 sell

Stupid question why is it username an pword as opposed to key and secret am i missing something.  or is username and password for tradehill and it should be key secret for gox?

cheers.

check it out!

Just check the functions "buy" and "sell" in my source code. Its less than 10 lines for both It won't get any easier than that.

update posted to the bot. when i was re-doing some numbers earlier, i forgot to have the next buy and sell points actually calculated. that has been fixed.

It's not ready yet due to some security issues that were pointed out to me earlier by Jine from Bitcoins.lc so please, dont use it. if you could, please remove the link for the time being.

i would like to make it open source, as i dont really have anything to hide, but i'm just not sure where to begin, lol.

EDIT:

(Coded in VB .Net)

i have removed a few things from the bot as there seems to be interest in it, so before anything goes live, i need help making a few changes:

there is a settings file that contains your username and password for a few things, i encrypt this based on a key in plain text in the file.

any decent ideas on how to get around this?

EDIT:

http://dl.dropbox.com/u/21251183/Bitcoin%20Bot.zip

open source. entire project file (actual bot is located inside the debug folder).

rip it apart, abuse it, just be careful

Let me know what you guys find or a better way for me to maintain the source.

Logic behind the buys / sells

it uses the ticker data and build averages from there.

there is a definable running average to based the high and low points, and i calculate a Simple moving average and an Exponential moving average from the ticker data that is based on a user defined depth.

from there, when the averages cross and the price is above/below the defined average percent, it attempts to place a buy/sell order at the ticker price. it doesnt always work. the next step here is to work in the market depth to place a valid order that would be placed.

runlinux had a bot in his signature. gui etc.

could be, what u need, he didn´t advertise directly in a thread, and i´m wondering, if its still available.
also, i´m no programmer, and don´t know, what this thing might do.

"Try my bitcoin bot at your own risk! http://dl.dropbox.com/xxxx"

edit: i pmed runlinux after i posted this, and he asked me, to remove the link. so i did.
any professional, who could look at the source, would be veryvery much appreciated

I know it's a sensitive topic, but I can't seem to find a simple buy/sell bot...And I have very little exp with PHP. Would it be possible to alter the code to 'scalp' to make a profit with a fee based Mt. Gox account? Adding something to sell if price is greater than .06% of the buy price?

Hmm, no more comments to the trading bot at post #35? I was expecting a bit more feedback considering the strong interest of the people here

Just replied.

But why is your php dir "phpchroot" Sounds like chroot? Maybe php lacks access rights. If you PM me your ICQ/whatever I'd be willing to help if u can provide me a shell.
