#Need help for background shading a range from previous trading day
#hey 5/14
#Would anyone know how to create a code which put imple white background shading on today's chart covering a range of the following 6 items;
#THE LAST 30 MINUTES OF PREVIOUS DAY'S:
#1) 20 sma
#2) 20 ema
#3) 200 sma
#4) 200 ema
#5) closing price
#6nd
#THE LAST 45 MINUTES OF THE PREVIOUS DAY'S:
#6) Price action (the candlestick price info range)
