Please pardon my greenpea question, but...... Im familiar with how to read a chart....looking for points of resistance in a stocks movement etc., and i know how and when to place a buy or sell bid, and i understand that if i sell i need to set a "limit" price for when i want it to execute. But....... can someone explain in simple terms, how is does it happen that those "resistance" points develop so evenly? Example - lets say a stock has been at $5.00 (upside) a week ago and is now going down and is at $200, but starting to go up again. Then all of a sudden we see it right at $5.0000 again!! The a couple hours later it does down and right back to $5.0000 even!! How does that happen, when the broker (Etrade) sets the bid and ask figures and theres a small gap there, (price-wise) that allows the trade price to fluctuate??? HELP!!!
