[GT] Weekly MACD on newer symbol - how much price history required

["Todd Turner" <todd AT turnernet.org>]

Hi All,

Just getting started with GeniusTrader.  Some of the symbols I follow
are fairly new (HED.TO), and I find that running MACD on the weekly
timeframe results in no data for MACD.

The MACD at stockcharts.com started showing MACD in december, and the
signal line and histogram in feb.

Does anyone know offhand how many samples are required before the GT
MACD indicator starts returning a result?

Thanks

Todd
