The ShavenHead() and ShavenBottom() candlestick functions would meet the definition most of the time. That said, there is also what is known as a Full Marubozu (where there is no shadow on either side of the candle) which I would think would be a fairly rare pattern.
We'd probably need the exact criteria to write this to meet your needs. I have found some web sites that say it's OK for there to be a very small shadow. If so, we would need to know how to define "very small". You can try the formulas below, although I doubt it would find very many results.
{Bullish Full Marubozu}
C = H AND O = L
{Bearish Full Marubozu}
C = L AND O = H
You could put one formula in Column A and Column B and then put a Filter of:
ColA OR ColB
