I left the bot running for 20 hours, using the settings of woutie70. Here's the data of the last transaction and the accompanying chart. The initial $fake_btc_balance was set to 2.

*** Processing order...array ( 8 )
["type"]=> string(3) "ask"
["amount"]=> float(1.8646517758757)
["price"]=> string(9) "952.99500"
["datetime"]=> string(19) "2014-01-12 20:12:07"
["prem"]=> string(6) "profit"

The results are not very encouraging, but I'll do another overnight run with the default settings from github and see how it goes. intrd, please push the new chart code to the repo, as pChart isn't very legible after a few hours.

Did you ever perform another overnight run?

As a matter of fact, I've left the bot running since my last post. It started at 2 BTC and again slowly lowered to 1.7 overnight. Now it is at 1.919 but I can't see the graph as I'm running it on an old Pentium 3 and it times-out drawing it.

Anyway, it clearly needs tweaking, but presently I don't have much free time to devote.

Nice! Looks like you moved it over to HighCharts/HighStocks javascript charting.

First of all, thanks for making this tool open source. I believe that with enough feedback from its users you'll deliver a solid final product. I'm using it right now on linux at paper mode, testing to see how it goes, using the settings woutie70 reported as "perfect".

The least I can do is provide a good start_hal10k.sh for UNIX-like systems:

Code:

#!/bin/sh

#export HTROOT=/srv/http/bitcoin/hal10k

[ $HTROOT ] || { echo "Please, edit $(basename ./$0) and set the correct HTROOT path."; exit 1; }

while true; do
echo Start time is: $(date)
cd $HTROOT
php start.php
done

I'll leave hal10k (what a cool name, BTW) running all night and report back with the results.

@initrd: Have you thought about using ta-lib (technical analysis library)? There is a PHP/PECL extension. Might save you the time from having to re-write each technical analysis function you want to use (ie. SMA, EMA, MACD, etc)

At the chart.php i've created a trick to optimize graph generation,
just turn on "$pular" and the graph is rendered discarding useless information..
but surely it would be better to generate the graph client side..
(I'm planing run HAL at my Pi too..)

About macd, finishing here..
thanks @yahma and @whydificult for the tips..

Code:

$control=(count($F1)*12)/100;
$control2=(count($F1)*1)/100;
$pular=false;

Will look into it. BTW, tried running it on my rasp-pi and it works for the most part (chart rendering is slow), except when the chart becomes longer than 1 day, then PHP hits the cpu limit time when rendering through pChart API. I might look into replacing the server side chart rendering with something client-side (ie. Javascript).

Hey people,
I'm creating the v2.3 HAL w/ some new features, one of which is the MACD analysis, however.. I need some way of getting data from the last 26 days and the maximum of bitcoincharts returns is about two days..
does anyway to solve this problem or can i do the MACD basing in a shorter time different EMA pattern of "12-day - 26-day"?

Suppose you could use 12-min / 26-min (or 12-hour / 26 hour) MACD for intra-day trading.

I'm workin on MACD right now,
I have not started integrating btce and vircurex, It would be great if you could help integrate these other exchanges..

Nice project! I would like to help out if I can. What is the current status of BTC-e and Vircurex api?

I left the bot running all night with default settings and I've lost almost 20% of the amount I had. Apparently it's selling low and buying high, always:

What should I change in the settings to stop this behaviour? Is there any reason for this?

Can't say for sure, but it looks like a lag due to the order-queue/lag at Gox is causing your trades to be delayed slightly, which is enough to cause serious problems. It does look like the bot is trying to buy when the short MA crosses over the long MA, and vice versa.. just by the time the trade executes its too late.

p.s. I've done much bot programming before, and unless the paper-trading simulates all the nuances of a real market, its VERY unlikely the bot will act the same IRL vs. papertrading
