Let’s start with a Pin bar, can you post the correct definition of Pin bar or a link to it?

I found this definition of a PinBar at https://www.learntotradethemarket.com/forex-trading-strategies/pin-bars-forex-trading-definition, this is the screener (unused variables have been commented out):

// definition of a candlestick
//
Body      = abs(close - open)
UpperWick = high - max(open,close)
LowerWick = min(open,close) - low
//Wicks   = range - Body
//Bullish = close > open
//Bearish = close < open
//

//
PB        = body <= (range * 0.10)      //Body must be smaller than or equal to 10% of the candle's range (very small body)
bullPB    = LowerWick >= (range * 0.67) //Bullish PinBars should have a lower wick greater than or equal to 67% of range
bearPB    = UpperWick >= (range * 0.67) //Bearish PinBars should have a upper wick greater than or equal to 67% of range
BullishPB = PB and bullPB
BearishPB = PB and bearPB
PinBar    = 0
IF BullishPB THEN
   PinBar = 1
ELSIF BearishPB THEN
   PinBar = 2
ENDIF
SCREENER[PinBar](PinBar as "1=↑,2=↓")

It’s fairly simple to add other patterns, or make a new screener for each additional pattern.

Should you need further help, let us know.
