As price action trader, we attempt the see the hidden strength of buyer in sellers candle and vice versa. I use simple calculation of candle wick to body -proportion to assess the strength. This script identifies the proportion of buyers and sellers in any given candle in form of %. Sellers are given in positive % and buyers are given as negative %. By moving the cursor to the interested candle the values can be seen.
While this will not be useful for decision as sole trading system, I use it as adjunct, whenever I analyze the data.
