Your statement reminds of me the trading style used by yoddutfx in his forex trading journal - mainly because he's a pullback type of trader. You are correct with your advise that we shouldn't entering the market as soon as there's a new high in the market or what I consider as breakout. Plus, it's kind of risky to enter the market at top, unless we are intend to enter sell at top. But if we are looking to enter according to the breakout trend, which is buy, then it's always better to wait after correction has been made. Or, in other word, wait to buy at deep.
