This is the big surprise for
candle lovers. A candle that functions as a reversal of an upward trend should cause
price to drop. Thus, a close above the top of the preceding candle would be a failure because price climbed instead of fell, whereas a close below the previous low would be a success. Similarly, a continuation candle should have price break out in the same direction as it entered. If price rose into the candle, for example, it should break out upward; a downward breakout would be a failure. How many of the 103 candles I looked at passed or failed according to this method?
Passed: 69%
Failed: 31%
If you listen closely, you may hear the half-glass-full people screaming. Yes, 69% of the candles worked, so let’s discuss additional tests. If I say that a success rate of less than 60% is considered just random, then how many candles worked at least 60% of the time? There are 412 different combinations of 103 candles that acted as reversals or continuations in bull and bear markets. Of the 412, only 100 candles qualified, so the answer is 24%.
If I filter the group by using a frequency rank of 51 or better, then just 10% qualify. The 51 rank is about midway in the list of 103 candles. As a reference, the candle with rank 51 appeared 1,973 times out of 1,204,083 candle lines in 500 stocks over 10 years, including bull and bear markets. In other words, just 10% of candles work at least 60% of the time and occur frequently enough to be found.
If I raise the bar to a 66% success rate (meaning the candle should work as expected in two of three trades) and keep the frequency rank the same, then only 6% qualify. That means just 6% of the candles I consider to be investment grade. Please remember that this applies only to stocks and not futures, exchange-traded funds, or other security types, so the results could change dramatically.
The following lists the investment grade candles:
- Above the stomach
- Belt hold, bearish and bullish
- Deliberation
- Doji star, bearish
- Engulfing, bearish
- Last engulfing bottom and top
- Three outside up and down
- Two black gapping candles
- Rising and falling windows
