Engulfing/Inside Bars

Very basic script to help discretionary traders with their candlestick pattern analysis
This script shows a colored arrow on top or below the candlestick indicating a bearish/bullish inside bar formation
also shows text with "bull" or "bear" on top of the candle when a bullish or bearish engulfing pattern surges.

big thanks to the pinescript reference manual & everyone that has open source codes bc i got stuck 50 bajillion times
Cheers.
