1. I'm a little bit confused about your statement regarding the EMA line crossing ("The bot executes trades automatically, without a warning, according to the current trend. It does not wait for the EMA lines to cross first!").  
Isn't it always a crossing of the lines when the treshold value under option is >0% ?
The treshold defines how much the two lines need to be apart to trigger a trade.
It has nothing to do with crossing.
For instance, if you have an uptrend lasting for a week - there will be no cross for a week - the last cross was a week ago.
But you are still able to figure out from the EMA(short)-EMA(long) difference that the trend is up.
And the treshold is there to protect you from unnecessary buy/sell swaps every few hours, when the two lines are not as much crossing, as they are rather aligned.
[/quote]

This is what i first thought by seeing the treshold option. If I understand it correct a trade will be triggered by a EMA line cross, which is a change of the polarity of EMAslow-EMAfast,  *AND* a difference in EMAslow/EMAfast larger than the defined treshold vlaue. If only the polarity of EMAslow-EMAfast changes but the treshold value will not be reached it will not trigger a trade. If the treshold value would be nearly 0% the trade would be triggered by the EMA line cross. Right?

Almost right.
Except that there is no check for a "change of the polarity".
Only the current difference is being checked.
For a long term it doesn't matter.
For a one shot term - you may want to consider starting the bot at the moment when you see the first cross. And it of course depends on what you're holding: BTC or USD.
But I'm assuming it doesn't matter, because you already are at the right position with your BTC/USD balance, after you did the last cross manually. The bot is just there to help you further Tongue

For a long term it doesn't matter - think about it.

Got you. Thanks for the explanation.

Is my understanding correct that all trades, if triggered, are only happening at the full hours? What do you think about a modification which is still calculating the EMA's on a hourly base, but continuously? I'm thinking about a faster way to catch a fast market move.

Another question came up into my mind. I use my google account to sync chrome between different computers. Therefore I guess the trading extension will automatically run in different instances. Is this a problem? And where will the settings be stored (API-key, etc.)?

I will send you a first small donation for your great work.

Cool I was thinking of trying it too with the default settings and if it makes any money you will get regular donations.  Does it work in your home currency or just US dollars?

It's probably a right way to go.
But this extension just does what it does - you're welcome to develop it further.

No, I don't see a problem here. At least as much, as when it comes to running different instances.. mtgox wont let you sell more than you have - no matter how many instances you try Smiley
But I personally don't let Chrome to "synchronize my settings", or whatever they call it.
No, I wouldn't want my secret mtgox api keys to be sent all around the internet Smiley

I don't care. Please don't tell me that.
If you like it, just send the 0.01 BTC, as it says in the options.

I don't need it to run in my home currency. USD market is much better.

The current version of the tool has only USD (hardcoded) in the sourcecode, but I don't see any reason why it should not work by simply changing the currency in the existing code.

As for the record: I personally don't use this bot - just for testing.
I have more advanced solutions, harder to be turned into simple chrome extensions.. Smiley

Please upgrade the bot to do it continuously and add your donation address too.

How about maybe randomizing the hourly buy/sell times of each bot to help maybe stop any mass market manipulation in case this thing takes off?

Automate it!

This will be a nice way to preempt all the people running the default strategy. Set it to 10-20 EMA and get in ahead of all the 10-21 guys.

I'm just going to play with 1BTC but any advice on settings is appreciated.

There is a topic Goomboo's Journal, in the Speculation board - I learned a lot there.

Let me present you a Chrome extension that is able to automatically follow the trading strategy explained by Goomboo in that topic (so people could get some sleep).

How it works
  • This is not a high frequency trading bot. It is making decisions to trade, based on H1 historical prices (1 trade every 2 hours, at most)
  • The bot executes trades automatically, without a warning, according to the current trend. It does not wait for the EMA lines to cross first! Read also here
  • Any SELL executed by the bot will sell all the bitcoins available at the account. Any BUY will spend all the USD you have there, turning them into bitcoins

Installation
  • You can install the extension here: https://chrome.google.com/webstore/detail/iejmifigokhpcgpmoacllcdiceicmejb
  • After installing, wait for it to fetch the historical prices and then (after the "progress bar" turns into a number) go the Options to configure your MtGox API Key (also some other options if you want)
  • After you configure the API access, just leave your browser running 24/7 and it will be trading for you, according to the trend

Security
I don't care about any feedback like 'I don't trust you', so don't bother letting me know. In fact if I were you I wouldn't trust myself either. Smiley
But here is what you should know to protect yourself from a potential fraud:
  • The bot uses the MtGox API and it does not require you to be logged into your MtGox account at any time. So better don't be
  • Setup the API key (in your MtGox account settings), to only allow get_info and trade access right - this way the bot cannot do you much harm, even if I wanted to

Warning!
This is an early version - I actually made it yesterday.
Until more people test it and the code gets well reviewed, I strongly advise you to try it only with a testing account and a small amount in.


I'm looking forward for any feedback or questions. Otherwise, have fun with it! Smiley

Is all this just a plan to get them market trading to your advantages  Wink

Hour   Price   EMA(10) / EMA(21)
Balance = 1.00 BTC + 0.00 USD
