[GT] Problem with display_indicator/EMA/revision 599

["João Costa" <joaocosta AT zonalivre.org>]

There is something wrong somewhere, and it seems to have happened in
revision 599.

If I do:

svn co --revision 598 https://devel.geniustrader.org:8082/svn/trunk/GT
svn co --revision 598 https://devel.geniustrader.org:8082/svn/trunk/Scripts

And then run:

display_indicator.pl I:EMA EURUSD 20

it works fine. But I can't get it to work with newer revisions.

>From revision 599 onwards, the above display_indicator call returns no
data. This does not happen with all indicators, apparently only with
EMA and others which depend on EMA like MACD.

Revision 599 has the following log entry:

Change all scripts to use consistent options for periods.

Thomas, if you have an idea of what might cause this, that would save
me debugging time.


We need unit tests to catch these things as soon as possible, and I'll
start creating them when i get a chance.  Actually some of it was
started a long time ago i think, but haven't had a look at it before.
