YESThe pull-back in prices is not justified if you just want a discount on recent prices. What it is useful for is as a test of the trend strength. So if price drops in an uptrend it's valid to set a buy entry order above the pull-back and wait to see if the market will be bullish enough to continue the trend. If the entry price is not reached, you can make other plans but it will have cost nothing.
and do not forget that if the prices drops in an up trend the faster it resumes the up trend the more eager buyers are.
so saying that you must wait for a two leg pull back to buy is ridiculous.
