How much does this strategy rely upon Bitcoin's continued extremely high volatility? 

I expect the volatility to decrease as the market becomes more mature (more actors, more based on the actual value of bitcoin, less hacks, more reliable bitcoin companies). And at some point the bitcoin technology might stabilize (currently fpga or ASIC could shake things up).

As volatility decreases, there were be more sideways action, and the fees will eat up more or all of your profits.

I could have, but you should not be trusting strangers in internet to take care of such stuff.
It's a piece of software, which you run on your PC, that deals with your money - you don't know me, so you shouldn't be taking it from me if you cannot understand what is inside.
Otherwise someone will screw you over one day - and I'm not being cynical here, it's just life that we all need to deal with

yep, I'd always make sure any script had been checked first by someone that I trusted - I wouldn't want it to go all Linode on me, or as you say posted as open source here, like Jessie's Bitcoin alarm free/donations

What I can do to help you..
You tell me what do you actually need and I can post some simple scripts here, so others could verify if I'm not screwing you over with them.
And then you can run them on your pc, if you want. I can eventually tell you what you need to install first - a software from some trusted source, like google, oracle or microsoft

that sounds great, thank you - when I have a little time I will look more in to what I might want, I imagine something like being able to easily enter a pair of EMAs or SMAs & that buy/sell action was triggered when they crossed + x% (x also settable & maybe % move more in the same direction or time? or combo??)

But basically, as when it comes to bitcoincharts+bitcoinica, I believe all you need is a continuously running web browser - you can afford it, cant you?

yep, my comp is on 24/7 - I don't think that it uses much juice & goes in to sleep mode after a while of afk but I guess would still be checking the APIs etc

For the new mtgox api, which i think is much better, they have a crypto with some weird hmac stuff - I dont know how easy it would be to do it in javascript. Probably php would be best here, since their example actually works - and there is not much more one needs to add over that.

yep, to be able to buy & sell or trigger limit orders on Mt.Gox would be great

While you've been mulling it over... I should have something for you to try by tomorrow.
I will start a separate topic in the Trading forum, to not spoil Goomboo's Journal anymore.
Just want to test it a bit more overnight.

It's an extension for Chrome browser - trivial to install not so complex to setup very easy to use.
And relatively easy to review - just a few KB of JS code, with some ajax stuff.

I had already had my bot, quite more advanced, but since I was so bored today and I like coding Chrome extensions... I made it for you
Anyway, will let you know soon - stay tuned.

I'd like to thank everyone for participating for the past two months throughout this journal.  My intention has been to help individuals approach the markets in a systematic, rational, and tested way.  Also, I have tried to "throw the ball into your court" by telling you how it is: you will more than likely fail if you don't own up to your decisions by testing, scrutinizing, and attempting to disprove your edge.  My hope for you is that you take responsibility and put in the necessary time and effort to protect the money you have worked hard to earn.

I do not have time to continue posting on a message board.  I wish you all the best in your trading endeavors.

I use:
-Ninjatrader - backtesting optimizing
-Excel - taking Ninjatrader's output and applying formatting to "pretty" it up


Steps I followed:
1.  Download Ninjatrader and learn how to import data and create custom instruments
2.  Download the data from www.bitcoincharts.com and modify it in Excel such that it can imported (they have some mistakes where opens are greater than highs, etc.)
3.  Import the data into Ninjatrader
4.  Create a strategy
5.  Backtest and optimize the strategy
6.  Export the data to excel
7.  Put it in a pivot table, color the range, format it
8.  Put it in a picture and upload it

For anyone who is interested in stock, futures, forex, or commodities trading, I highly recommend Ninjatrader - it is a solid, solid platform.
