Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Thanks!

i guess that I fixed it. Used fgets() instead of readline(). Please download new version Enjoy.

Congratulations on this very interesting little project, and thanks for sharing.

I had one major problem/comment for you on this:

The order depth table does not appear to be synched or correct for me.  It's either lagged, delayed, (cached?), or missing the top few best buy/sell orders.  I can't tell without taking a closer read of your code if this is ToyTrader's problem or with Mt.Gox's API (I would assume the former) but when I run and update this, the order depth chart is not the same as what is shown on https://mtgox.com/trade/history

Thanks again for sharing this and I look forward to seeing further refinements.

ps: I couldn't for the life of me get rid of that timezone warning that comes up with every refresh.  I finally fixed it by just putting it in the command line:

php -d date.timezone="America/mytimezone" -q mtgox.php

[toyotasupra]

Thanks for your interest

New version (0.0.4) sorts a feed from mtgox, so if appears any differences - they are on mtgox side. Each refresh downloads a new data from mtgox, and never cache it.

[toffoo]

Hello again,

Thanks for checking this out.

But I just tried v.0.0.4 and it looks like the depth chart is still missing the top best bid and ask prices.  I looked at the raw Mt.Gox API JSON data and they are there, so maybe check if your code is doing something screwy with the first entry in the list or something.

Thanks again.

OMG. what a shame... it was classic mistake, i forgot that arrays in php is from 0

Please update mtgox.php from github 0.0.5 version.

Thanks

Great, looks much better now.  (I'm no PHP programming expert, but I figured it was something like that.)

I would say that this little tool borders on being quite useful already.  Here are a few other thoughts for improvement:

1.) there should be a quick command to immediately cancel all open orders, perhaps just "c" or "c all".  When things are moving fast it can be real tough to "l" to list all the open orders and then type in "c" with the each oid to cancel everything.

2.) there are a few places, like "t" to list the recent trades, where the timestamps are in Unix time.  They should probably be converted to human readable format.

3.) I cannot backspace once typing in a command or an order.  If I mess up, I need to Ctrl-C the entire script because my backspace just gives ^H at your command line (but works fine as a backspace in my shell).

4.) maybe a header row for the "l" list that explains what all the numbers are.

I'll let you know if I can think of anything else useful as I start to use this more.

Thanks again for this fun little tool and I look forward to any further refinements.

For some reason, your application is not working anymore for me.

All i get is this (i got this error days before MTGox was down):

Code:

Mtgox is currently down.  For more information, head on over to the discussion forum and read any of the last 300 threads or so.

Like i said i already got this error days before MtGox was down.

[TheRandomGuy]

 Wow! Nice! Will try later.

Hi,

*** curllib: Operation timed out after 30001 milliseconds with 0 bytes received

This can be avoided by inserting

Code:

curl_setopt ($ch, CURLOPT_USERAGENT, 'Wget/1.9.1');

in the function doRequest() in file curlib3.inc.php.
(found this tip on the mtgox support forum).

But starting with the MtGox restart, there is another problem: the script hangs after displaying the funds. What I get is only:

Code:

Did the API change somehow?

[romsek]

Thank you very much, twinpeaks, that solved the problem.

Now i get the same output like you.

[twinpeaks]

Hey, just got it working again!

I added

Code:

user_agent="PHP"

to my php.ini

Instead of inserting

Code:

curl_setopt ($ch, CURLOPT_USERAGENT, 'Wget/1.9.1');

uncommenting the line

Code:

curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)');

works too.

The entry in php.ini alone is not enough, it seems you also have to set one of the useragents in curllib3.inc.php.

The formatting is a little off, but it works. :-)

[romsek]

That did the trick. Thanks again!
