indicator to calculate pips between 2 horizontal lines

hi everybuddy,
i need help with a indicator.
i need a indicator which can calculate no. of pips between 2 horizontal lines.
if i draw 2 horizontal lines then it should calculate the no. of pips between the two horizontal lines automatically.
thnx

Do you know that MT4 has its own ruler tool, that measures the number of candles, and number of pips, between any two points? (It's not documented in the on-line help).

It's explained in this post, under the section entitled "Crosshair mode, and ruler tool".

Does this suffice?
