Subject: [amibroker] Re: Sigma
Bands
Among the others, take a look at<A
href="">http://www.traderiskmanagement.com/warning.htm!!!!!What
is so important for these bands??I tried CSCO from the Wealth-Lab code and
NO trades for the last year or so. Is this the importance, not to trade at
all and take the B&H probable profits ?
Not surprisingly, the code does not
have a buy/sell condition because Sigma Bands are not noarmally used to
give signals. As with any OB/OS indicator, or imo with any
indicator, they are not properly used in a vacuum but rather in
conjuction with other indicators. Dimitris
