this is a snip of code from your coding 
candlesticks afl
I guess it measures the body of a 
candle
could you please explain how this works in 
simple english
BBandBot( Body,55,0.5); 
ThBotB =BBandBot( Body,55,0.5); 
 
so the bbandbot is a standard applied to the 
chosen item in the case body
and the 55.0.5 is ?
 
BBandBot function calculates lower (bottom) 
bollinger band from
array specified as a first 
argument.
Bottom bollinger band is calculated as 

moving_average( period ) - width * 
standard_deviation( period )
 
The author of original article Mr. 
Likhovidov uses this formula 
to calculate average candle body 
weight.
