I've known some friends and colleagues who say they never use TA and hit can't work anyway and its not for the serious players in the game. Then, when buying a share, they ask what is its price. And how high / low has it been say a month ago........
MarkBrown used to trade (100s at a time) big S&P futures contracts in the 80s (and can afford $500,000 supercars). MarkBrown is a storyteller (and never spends more than $5,000 on a car). I hope the former, not the latter is the true statement. And yes, it does matter: his posts take on a whole different meaning if he's FoS.
But in reality for that scenario only one can be right. So 50 are right and 50 are wrong. It is not a waste of time. It is an opportunity to found out how to be right in every scenario.
Expert says : Keep your stop loss very very small. Maxinger says : Don't panic and tighten your stop loss till sooo tight. Keep your stop loss big enough for market to move around. Give allowance for market to retrace deeply. Don't listen to people blindly. Analyse your Trade Journal, know your inner self, and decide how big or how small your stop should be.
Experts say : Trade only the main session Professional traders say : Don't listen to the experts. Do your own analysis, and trade the appropriate session. Experts are those who earn $$$ by writing. Professional traders are those who earn $$$ by trading.
