1)I`ve been learning all I could about trading, orders, order book. Now that after 2 years im haveing some profits i wonder why some things happens. I hope you could help me. If I look into the order book, it is suppose that if i see shares offered at a price, and i want to buy them, the order will be filled? FOr instance: I see 200 shares at 25$, and price is 24.25$. I deploy a limit order 200 shares at 25$ my order will be filled in any moment? 2) What that really means chase the market? I always hear dont chase the market ( i understand is enter lately into a trend. If there is a downtrend, Why the price could go back? Tx for help
