Quote from rt454:
I was going to say TA is making trading decisions on something other than income statements, balance sheets, PE ratios, PEG ratios, news, etc. I like your description better.
Thanks for that. The most correct definition would probably be: TA is analyzing market based on the information, provided by the "internal" market inputs only, such as price, volume, order book and possible derivatives/combinations of the above as opposed to fundamental analysis which uses "external" inputs, such as balance sheets etc. in order to make decisions.
Cut it down to just price for the sake of simplicity, otherwise we may discuss different combinations of market inputs forever.
