Hello, Up until my post no one had actually answered the original question i.e. QP cf Yahoo +/-, although the posts made have still provided valuable information.
You are the second one in who is on the money. Thanks for your post that offers a different point of view and comes from a base of greater experience. I don't mind being proven wrong and enjoy a good rebuttal. I've taken note of your suggestions and will factor them into future efforts. It is hard to give an honest review without being critical somewhere. It would have been more accurate if I had said I don't like excessive negativity or even worse, abuse. I don't think there is a call for it in public. I try to avoid it. I haven't made the claim anywhere at anytime that use of fundamental data will or will not produce positive trade outcomes. I have said that it is one of the main staples of popular investment culture and therefore should not be ignored. I haven't ignored Tomasz's warnings about the Yahoo data - I missed that one altogether and will have to go back and find it. I have cautioned others about verifying data at other posts in this thread. In any case I make my own value judgements after careful consideration.
