I am new here. Can anyone point me towards coding to run proscreeners searching for the following candlestick patterns:
A Wick reversal i.e. hanging man in a bear trend, shooting star in a bull trend), an extreme reversal (a large candle signifying exhaustion of the prior trend), an engulfing candle and a doji candle.
I asked if prorealcode would write the code for me and they referred me to this forum.
Many thanks, Charles
Hi, here you have an example:
// --- Candlestick Pattern Identifier ---
// Logic for DOJI
// Body is less than 10% of the total range
isDoji = (ABS(Open - Close) <= (Range * 0.1))
// Logic for ENGULFING
bullishEngulfing = (Close[1] < Open[1]) AND (Close > Open) AND (Close >= Open[1]) AND (Open <= Close[1])
bearishEngulfing = (Close[1] > Open[1]) AND (Close < Open) AND (Close <= Open[1]) AND (Open >= Close[1])
isEngulfing = bullishEngulfing OR bearishEngulfing
// Logic for WICK REVERSAL
upperWick = High - MAX(Open, Close)
lowerWick = MIN(Open, Close) - Low
bodySize = ABS(Open - Close)
shootingStar = (upperWick >= (bodySize * 3)) AND (lowerWick <= (bodySize * 0.5))
hangingMan = (lowerWick >= (bodySize * 3)) AND (upperWick <= (bodySize * 0.5))
isWickReversal = shootingStar OR hangingMan
// Logic for EXTREME REVERSAL
// Current range is 2.5 times larger than average range
avgRange = Average[20](Range)
isExtreme = (Range >= (avgRange * 2.5))
// --- Variable assignment based on pattern type ---
patternType = 0
IF isDoji THEN
patternType = 1
ELSIF isEngulfing THEN
patternType = 2
ELSIF isWickReversal THEN
patternType = 3
ELSIF isExtreme THEN
patternType = 4
ENDIF
// --- SCREENER EXECUTION ---
// Only show stocks where at least one pattern is found
condition = (patternType > 0)
SCREENER[condition] (patternType AS "Pattern Type: 1=Doji, 2=Eng, 3=Wick, 4=Ext")
You can also use this indicator to check screener
// --- Candlestick Pattern Identifier ---
// Logic for DOJI
// Body is less than 10% of the total range
isDoji = (ABS(Open - Close) <= (Range * 0.1))
// Logic for ENGULFING
bullishEngulfing = (Close[1] < Open[1]) AND (Close > Open) AND (Close >= Open[1]) AND (Open <= Close[1])
bearishEngulfing = (Close[1] > Open[1]) AND (Close < Open) AND (Close <= Open[1]) AND (Open >= Close[1])
isEngulfing = bullishEngulfing OR bearishEngulfing
// Logic for WICK REVERSAL
upperWick = High - MAX(Open, Close)
lowerWick = MIN(Open, Close) - Low
bodySize = ABS(Open - Close)
shootingStar = (upperWick >= (bodySize * 3)) AND (lowerWick <= (bodySize * 0.5))
hangingMan = (lowerWick >= (bodySize * 3)) AND (upperWick <= (bodySize * 0.5))
isWickReversal = shootingStar OR hangingMan
// Logic for EXTREME REVERSAL
// Current range is 2.5 times larger than average range
avgRange = Average[20](Range)
isExtreme = (Range >= (avgRange * 2.5))
// --- Variable assignment based on pattern type ---
patternType = 0
IF isDoji THEN
patternType = 1
ELSIF isEngulfing THEN
patternType = 2
ELSIF isWickReversal THEN
patternType = 3
ELSIF isExtreme THEN
patternType = 4
ENDIF
// --- SCREENER EXECUTION ---
// Only show stocks where at least one pattern is found
condition = (patternType > 0)
return patternType AS "Pattern Type: 1=Doji, 2=Eng, 3=Wick, 4=Ext"
Hi Ivan,
Thank you very much for your response. I do really appreciate it.
Best wishes, Charles
