Research shows that a tall price bar (candle line) indicates that the stock will
reverse direction between 67% (uptrends) to 72% (downtrends) of the time, plus or minus one day. This finding is
invaluable for swing traders, and other traders can profit from the knowledge as well.
Research I conducted shows that tall candles
(price bars) often, but not always, indicate a short-term trend change, that is,
they tell when a minor high or minor low is forming. Traders can use this
information to help time their trades. The method will not detect all trend changes
nor will it signal perfectly. Nevertheless, knowing when price may form a minor
high or minor low can help prevent you from trading just before a reversal.
Here are the recognition rules:
Tall Candle Setup: Recognition Rules
Look for price trending upward (for minor highs) or downward (for minor
Determine if today shows a tall candle by computing the average height of the
preceding 22 trading days (do not include today's candle). That is, subtract the
low price from the high for each of the past 22 days and average the result. This
is the average candle height. I tested the 22 day period and found it worked best
among 3-5, 10, and 22 days. Verify the 22 day look back period works best for your
Compare today's candle height (high-low range) with the average candle height.
If today's height is more than 146% above the average candle height, then you
have a tall candle. Tall candles are more likely to appear within a day of minor
highs and minor lows (that is, one day before to one day after the tall candle).
The 146% number is the median height of all tall candles found by research. You
might want to test different values.
