I am trading stocks for around 40 years. I was trading everything in these 40 years. But in stocks I am a successful trader and I was looking for a reasonable data basis for US stocks and found it in the IBD data basis. Furthermore I was surprised in the helpful reviews of "investor´s corner". A lot of these techniques were very familiar for me. But some ideas have been new. And as a old expierienced trader I must test these techniques, if they really work. And if you are following these rules, they work. Mostly publiced investment-techniques in magazines are only bullshit and marketing jokes only for the aim to promote the publisher´s name. Not so IBD.
