My experience is that there are so so many things one can look into..options, market sentiment, commitment of traders, market cycles, seasonal patterns etc ...now they even have algos scanning social media for sentiment etc etc Its impossible to get a full picture and so l stick with "Its all in the price...let the market guide you..etc"! However, if you find something that works for you..brilliant, get on it!
Heard today that only 10% of Goldman Sachs traders make a profit every year...and look at the research depts they have!
its as if 10% of their trades make big money and the rest lose and/or BE and good money management let's the bank make billions from those figures...same ratios as a lot of top traders!
