Maybe if you're looking at little intraday scalp trades on a noisy, unreliable minute chart, but Daily, and more so Weekly, Monthly and even Quarterly chart set ups are quite reliable. Not all of us are looking for quick, "gut instinct", lucky, minute by minute scalps and are quit content to wait and watch the longer time frames and calculate the Discounted Cash Flows for a given company. As for Pair Trading, it is considered a lower risk "arbitrage" strategy by Hedge Funds and used by them precisely for that reason, usually on a Daily chart.
