Time and sales volume final 1

hello, this is a volume script that depicts the basics of time and sales onto an accurate volume scale. what this can be used for is finding reversal to enter shorts, or puts and strong bullish movement to enter longs or calls. The green indicates buying and red indicates selling inside a candlestick. obviously when securities are exchanged there is an equal amount but this works off relative to the candle close and open to help determine a certain direction.
