Three Black Crows rules not respected

  I have been cleaning up and modifying a very useful Candlestick Patterns post by Violet here on this forum that I will post when I am satisfied that all the 8 patterns I want to include meet Thomas Bulkowksi’s analysis. Violet’s post is here: https://www.prorealcode.com/prorealtime-market-screeners/trend-reversal-continuation-patterns/

  Often when you believe a pattern should be indicated on the chart it is not. This can be due to some tight restrictions on the description/conditions of the pattern, perhaps concerning the range / ratios of a candlesticks body relative to other candles, but here in the case of the “Three Black Crows” I seem to be finding many examples on daily charts that are not being indicated?

  The code I have is:

  Three Black Crows

  // Bulkowski accuracy rate: 78% in a Bull Mkt and 79% in a Bear Mkt. Frequency: Very common. c1 = close[2] < open[2] c2 = close[1] < open[1] and close[1] < low[2] c3 = close[0] < open[0] and close[0] < low[1] // Closing prices are less than 1/3 from lows c4 = abs(close[2] - low[2]) < range[2] / 3 c5 = abs(close[1] - low[1]) < range[1] / 3 c6 = abs(close[0] - low[0]) < range[0] / 3

  1 2 3 4 5 6 7 8 9

  // Bulkowski accuracy rate: 78% in a Bull Mkt and 79% in a Bear Mkt. Frequency: Very common.   c1 = close[2] < open[2] c2 = close[1] < open[1] and close[1] < low[2] c3 = close[0] < open[0] and close[0] < low[1] // Closing prices are less than 1/3 from lows c4 = abs(close[2] - low[2]) < range[2] / 3 c5 = abs(close[1] - low[1]) < range[1] / 3 c6 = abs(close[0] - low[0]) < range[0] / 3

  Any ideas? Am I correct in thinking many of these white falling candles should qualify as Three Black Crows on the Daily £/$ in Aug 2008?

  I don’t know, did you test each of the condition?

  I get many patterns, but not on that dates:

  // 3 - Three Black Crows ********************************* // Bulkowski accuracy rate 78%, frequency: very common c1 = close[2] < open[2] c2 = close[1] < open[1] and close[1] < low[2] c3 = close[0] < open[0] and close[0] < low[1] // Closing prices are less than 1/3 from lows c4 = abs(close[2] -low[2]) < range[2] / 3 c5 = abs(close[1] -low[1]) < range[1] / 3 c6 = abs(close[0] -low[0]) < range[0] / 3 return c1 and c2 and c3 and c4 and c5 and c6

  1 2 3 4 5 6 7 8 9 10 11

  // 3 - Three Black Crows ********************************* // Bulkowski accuracy rate 78%, frequency: very common c1 = close[2] < open[2] c2 = close[1] < open[1] and close[1] < low[2] c3 = close[0] < open[0] and close[0] < low[1] // Closing prices are less than 1/3 from lows c4 = abs(close[2] -low[2]) < range[2] / 3 c5 = abs(close[1] -low[1]) < range[1] / 3 c6 = abs(close[0] -low[0]) < range[0] / 3 return c1 and c2 and c3 and c4 and c5 and c6

  Thanks, running the code separately in it’s own indicator (instead of being combined with the 7 other Bulkowski patterns), made me realise that I had a trend filter (SAR) switched on in the Bulkowski indicator. 

  Oddly with the trend filter switched off and the exact same code as above I did gets lots of Three Black Crow patterns during that chaotic period in Aug 2008: Pls see screenshot, not sure why you didn’t, once I get the Morning Star sorted I’ll post the 8 Bulkowski (upgraded) patterns indicator.

  Cheers Nicolas,
