"I understand this is your first dead client," Sabian was saying.  The
absurdity of the statement made me want to laugh but they don't call me
Deadpan Allie and lie.
-- Pat Cadigan, "Mindplayers"

Currently the script is reports (as fast as possible) any arbitrage opportunities and uploads the report to my webspace.
I will be extending this script to a trade bot later.

Donations welcome, if you would like to buy the script for your own use etc the price is 1 btc / equiv in alt coins (price neg).
I shall keep this service running for the foreseeable future.

This does not compute.

Update: I see, the .txt file updates.  That makes more sense now.  Using .txt is a bit misleading - thought it was a static file.

converted to html, threaded the code, tidied up and added some more ARB's.

updates every ~10 seconds or quicker depending on lag between me and btc-e

Thanks!

I'd be interested in the trade bot based on this. Free or not :)

If I had to take a stab it would be what volume is available at those prices to arb.

No cronjobs to refresh it I take it.

Bump - any action OP?

Hi mate, the pc hosting it was restarted recently and I manually kick it over.

I'll bring it back online tonight :)

Do you calculate every possible aribtrage and show the 7 best ones, or do you calculate only those 7 ones shown ?

I really like the simplicity of the page.

I only do the 7 shown, I have thought of only showing positive arb ops but it would result in the page being blank most of the time.

Simiplicity is key, especially for a site that needs to refresh as often as arby does.

How am I supposed to read this?
Does
Quote
[ARB 1] 1 BTC =           98.802 USD =      30.52748776 LTC =        0.9855891 BTC - Depth:       0.1996 BTC
mean BTC -> USD -> LTC -> BTC ?

Also should the script not only show profitable trades?

yes you read it from left to right.

No.

can someone explain how you read the profit on this?  I am not understanding. At first I thought the last column was going to show you the profit made.

It shows how much btc you will have at the end. If the number is larger than 1 then you will profit

Is it possible to color code the lines to show which is profitable and what isn't (Green = Good) (Red = Bad)?

Sure is, when I find some time to scratch myself I'll add something to that effect.

Hey, is this still active. If the dev has lost interest, I wouldn't mind taking over. I will of course still give all the money from selling the bot to the dev

code is still available but I turned off the script to save on my local bandwidth.
I will update the code to include some of the newer altcoins and make a post.

Great, thanks.

Once the code is updated, I can throw a copy on a VPS so there aren't bandwidth constrictions if wanted.

I have created a custom script to calculate your profit from trading between two exchanges. You can customize the Buy and Sell price. The script also takes into account the transfer fees and Buy and sell fees. I plan on working on this script more but I want to see how much interest I receive. Would like to include:

  • Live updates on prices from different exchanges.
  • Quick trading with Trade Secrets and Trade Tokens.

I can't wait to here the feedback.  http://theark.io/projects/btcarb/ (http://theark.io/projects/btcarb/)
