This is the code for your stock screener to find doji candlestick piercing pivots points (bearish signals when the high crosses one of the pivot points and bullish ones when it is the low of the candle).

// --- settings
DojiSize = 20 //x% percent of body size compared to the complete range of the candlestick
mode = 1 //Pivot calculation method
// ---

If Day>Day[1] then
If mode = 0 then
Pivot = (DHigh(1) + DLow(1) + Close[1]) / 3
Elsif mode = 1 then
Pivot = (Open + DHigh(1) + DLow(1) + Close[1]) / 4
Elsif mode = 2 then
Pivot = (DHigh(1) + DLow(1) + Close[1]*2) / 4
Else
Pivot = (Open*2 + DHigh(1) + DLow(1)) / 4
Endif
R1 = 2*Pivot - DLow(1)
S1 = 2*Pivot - DHigh(1)
rR2 = Pivot + (DHigh(1) - DLow(1))
S2 = Pivot - (DHigh(1) - DLow(1))
R3 = R1 + (DHigh(1) - DLow(1))
S3 = S1 - (DHigh(1) - DLow(1))
Endif

doji=(abs(open - close) <= (high - low) * DojiSize/100)

bullish = doji and (high crosses over pivot or high crosses over r1 or high crosses over s1 or high crosses over rr2 or high crosses over s2 or high crosses over r3 or high crosses over s3)

bearish = doji and (low crosses under pivot or low crosses under r1 or low crosses under s1 or low crosses under rr2 or low crosses under s2 or low crosses under r3 or low crosses under s3)
