Earlier during October 26th, 2010 SDA2 Trend Trading System  is introduced in marketcalls.
After revising my old strategy( which contains too many flaws in the system) releasing the 
newer Version of SDA2 Trend trading system(Version 2.0).This Version is more optimized for 
Long Only Signals (Short Signals are treated as exit from the long position AND stay away 
from the market). In the older Version the SDA2 trading system wont perform good if there 
is any gap up OR gap down in the trading instrument. The new Version overcomes those flaw 
AND it is more optimized towards those Gap Up/Gap Down.  */
