Thanks for the link. Does this mean you'll be switching to the opposite strategy once the next bubble starts? The CPPI that's discussed in that link? Buying more Bitcoin when it is clear that the market is going up and selling when it is going down.

Interest that two completely opposite trading strategies are perfectly valid, just depending on the current behaviour of the market!

Why don't you use the backtesting online software that was discussed just a few posts ago (http://cryptotrader.org/)?

If you're not happy with failed trades, then maybe look into adding a threshold after the cross before trading or use a longer sample size instead of two hours.

Thanks! Its a bit concerning that beginning and finishing prices need to be the same. They won't be in the real world. I would've expected the small profits that this bot provides would be valid for any price of BTC as it automatically rebalances?

If BTC goes down to 0 USD shouldn't the bot automatically keep buying BTC and keep my total balance the same?
If BTC goes up to 1 000 000 USD shouldn't the bot automatically keep selling BTC and keep my total balance the same?

If the above is true, why does my total balance drop by 20% just because the starting and ending prices of my simulation are different?

I have attempted by own implementation of the goxtool rebalancing bot located at the following link:

http://cryptotrader.org/backtests/CboFCRyQaLn2Zv76r

Be gentle, I'm not a programmer!

Anyway the results were not very promising, no matter how I tweaked the values, it seems that I will always lose roughly 20 percent of my initial. If I increase the range of the backtest to past the April bubble then the gains are a little more respectable, but something like the popular EMA crossover method would do better in all regards.

Unless there's something wrong with my script, which is very likely. Can someone more skilled at programming than myself look at the link and let me know if there's anything wrong with it? i printed out balances at every tick though and it seems to be doing the right thing.

Have you thought about trading on 2-4-6-12 hour systems? 2h system is interesting, a lot less sideline trades, but still decent amount of trades.

I switched to 2 hourly from 1 hourly after constantly losing trades because of the poor volatility. Its saved my ass plenty of times and I recommend it!

Thanks! AidoATP rocks too by the way.  Wink

Nice, I think the _panic.py is what I need.
7  Economy / Trading Discussion / Re: ncurses based MtGox live monitor and trading-bot-framework on: July 09, 2013, 07:09:36 AM
Is there a way to do market orders or "all in" orders? I can't do it easily with the current goxtool as I have to type in USD price and quantity of BTC.

Is there a way for goxtool to:

  • Calculate how many BTC given a certain amount of USD using the market price?
  • Calculate how much USD given a certain amount of BTC using the market price?

Once I have this number I can offset accordingly.

Hmm still no difference.

For what its worth, I removed node and reinstalled it and still same problem. I also ran into an issue with "npm install". I posted it below. Any ideas?

Yes I'm running a fresh clone of your GitHub project. I'm on Linux Mint at the moment and I'm pretty much stumped by what is causing this.

I suppose I can try and reinstall node and nodejs and see what happens...
10  Economy / Trading Discussion / Re: Gekko - a javascript trading bot for nodejs on: July 07, 2013, 05:36:15 PM
Can anyone help me with running the bot?

It just returns immediately from the program when I type "node gekko". No error messages or anything. npm, nodejs is installed. I did a git clone for installation of Gekko itself.

Code:
nii236@NiiEEE ~/bitcoin/gekko $ node gekko
nii236@NiiEEE ~/bitcoin/gekko $

Also, is there a way to disable certain types of trades. I want to do the following:

When EMA crossover signals a buy, buy on MtGox ONLY
When EMA crossover signals a sell, sell on BitStamp ONLY

Is this possible?

It would be pretty awesome to have a seamless box which contains a private key inside. No lid, no hinge, no screw holes. Just a cube. Have to use a hacksaw just to get the goodies within.

Soniq,

You have listed my BTC address as the change address, as opposed to my actual one. I have sent you an email but you haven't responded yet. Please let me know what you need in order to change it to the 1Nii236 address in the TXID I sent you.

The best way to teach would probably be to have an example. As soon as I sent my buddy overseas 10mBTC, it all clicked together.

One thing I learned travelling: the first thing to ask when someone tells you a place is dangerous is "Have you been there?" If the answer is "No," just ignore.

I am currently living in Africa.

Yes, it can be dangerous. It can also be safe. I'm still in one piece but there have been incidents suggesting how bad things can get.

Anyway, I have had the same thoughts as you about an exchange here and I concluded that it wasn't worth it. I'm still open to discussion though, PM me if you wish.
15  Bitcoin / Bitcoin Discussion / Re: Do you think Bitcoin will be used to pay employees? on: June 13, 2013, 11:27:10 AM
What are the difficulties faced in doing this with a company who has never heard of Bitcoin, and probably has no interest in paying out in Bitcoins? Can they pay that pre-tax amount to an exchange? How does it work?

If the company has never heard of Bitcoin it will require a little work simply because there is no "bitADP" (ADP is major payroll provider in the USA) at this time.  However if a company is interested it wouldn't require more than an exchange account that accepts wires from the US (like MtGox).  The exchange account would be in the name of the company. The cost of the wire plus trading fees is still <1% which is a reasonable cost to provide this as a perk for employees (a cost of doing business, traditional payroll also has operating costs).
*snip*

Wow thanks for the informative post! From the looks of it, I really doubt the payroll department of a big company is flexible enough to add in an option to pay out in Bitcoins. There is a set up and manual conversion of money and stuff (unless MtGox does its automated market orders like you mentioned) that would have to be done by someone who has no idea what Bitcoins are.
16  Bitcoin / Bitcoin Discussion / Re: Do you think Bitcoin will be used to pay employees? on: June 11, 2013, 08:15:44 PM
I receive part of my salary in Bitcoins.  The simplest way for a company to pay using Bitcoins is to make it an "after tax deduction elected by the employee".  My salary is $X USD.  The company already deducts payroll taxes, income taxes, and benefit premiums.  I elected (by written authorization) to have a certain amount of my salary paid in BTC.  The options my company gave me were a specific USD amount, a specific % of salary, or entire net (after withholding and deductions) amount.  

On Payday the company converts the USD amount to BTC using the volume weighted average exchange rate over the entire pay period.  Our company's program covers all costs and fees but a company could charge a reasonable fee for the service.  I am sure on a long enough timeline payroll companies like ADP will offer this.

Now there are other ways to do this but the advantage of doing it this way is that it is very simply for any company to implement.  All Payroll software allows post tax deductions.  The amount deducted becomes a credit on the company USD books and an equivalent debit is made on the company's BTC books.   The tax implications are already taken care of (other than any capital gains on rising value) as the taxes were based on gross salary.  The company can still deduct the entire cost of the employees salary with no changes to accounting.

it already corrected from 250. did a bounce, then went sideways for a while. this is a sell down.

dont deny yourselves of the fact that bitcoin is going down right now. the more important thing is to know what to do.

Sooo... what to do?
19  Economy / Speculation / Re: Goomboo's Journal on: June 06, 2013, 09:56:45 PM
^Well don't forget Goomboo only does daily trades now, specifically because commission rates are ridiculously high.
20  Bitcoin / Bitcoin Discussion / Re: Bitmessage Address Book on: June 06, 2013, 04:18:26 PM
Would be cool to have an import CSV feature of some sort for batch importing of addresses.

And doesn't this thread kind of get rid of the concept of anonymity in the first place?
