Regarding Calculation of Log Box Value in P& F chart

[Bidhan Saha-1764104472732]

Prashant Sir Ji, Namaskar,
I have another confusion reagring Box Value in P & F chart
(i) Suppose the Closing price of an instrument is 800 and i plot 1% x 3 Box Value size on Daily Time Frame i..e Price revered the X and O coloumn if Price +- 3% i.e. 3% of 800 = 24 and if price fall 770 then Reversed 3 Box in O coloumn i.e ( 1% of 800) 8 x 3 = 24 . But Sir My question is that now LTP is 770 and if the price fall futher the continuation Box size is 8 as calculated previously or 7.7 ( 1% of 770) which one.
(ii) Or the Log Box Value if Caculated on the EOD closing price of an instrument and any changes in the LTP through out the day is not effects the box Value.

Sir Please Clerify the matter ,
