Signal buffer with the pin-bar and martingale on next candle

hi, 

I planned to get a buffer signal "1" and "0" with the pinbar indicator.

attached sample indicator which I made. so I need to develop it when loss a trade, buffer again the same direction on next candle.

if loss second trade also then should change the buffer direction on next candle.

e.g if indicator buffer "0" as a sell signal, but the current candle is green.

      then indicator buffer again "0" as a sell signal in the current candle expiry.

      after that next candle also made green, then indicator should change the buffer direction to "1" as a buy signal. 

      need to change the direction in every two losses occurred till win.
