Heikin Ashi Doji screener

Thank you very much for the code. I added some code to check if there is a Doji in the previous candle.

// — parameters
DojiSize = 5 //x% percent of body size compared to the complete range of the candlestick
// —

if barindex>1 then
haclose=(open+close+low+high)/4
haopen=(haopen[1]+haclose[1])/2
xHigh = Max(haOpen, haClose)
xLow = Min(haOpen, haClose)
hahigh = Max(High,xHigh)
halow = Min(Low,xLow)
// Added to check if the -1 Candle is a Keiken Ashi Doji
haclose1=(open[1]+close[1]+low[1]+high[1])/4
haopen1=(haopen1[2]+haclose1[2])/2
xHigh1 = Max(haOpen1[1], haClose1[1])
xLow1 = Min(haOpen1[1], haClose1[1])
hahigh1 = Max(High[1],xHigh1)
halow1 = Min(Low[1],xLow1)
endif

data=(abs(haopen – haclose) <= (hahigh – halow) * DojiSize/100)
data1=(abs(haopen1 – haclose1) <= (hahigh1 – halow1) * DojiSize/100)

screener [data or data1]

I woul like to add some trend before the Doji (at least four green consecutive Heiken Ashi Candles or four red consecutive candles). Any help will be appreciated.
