Think maybe the thread should have been titled "Both Price and Indicators Lag". --This is because those who profess using price action for entries are also recommending entering once price has retraced or pulled back and then taking the entry when price has continued again in the direction of our trade.
True, though it has nothing to do with "price lagging". If your price is lagging, get a better data feed.
One waits for the market to tell him what to do via its behavior. This is the antithesis of the "guess and hope" strategy employed by those who just jump in for unexplained reasons, generally "feel".
