Modify this indicator. delay the arrow + add lines to connect arrows and count pips

hello. i want to delay the arrow that being drew in this indicator by 1 candle and add lines that connects every arrow with the arrow that comes after it and calculate the pips

the line after the down arrow calculate how many pips we could gain after the arrow appeared until the next arrow + it shows the best pips we could gain

in the first red line, if we opened sell, we will lose -40 pips if we waited the up arrow to appear. but at best we could've earned 214 pips.

and the next blue line shows that if we open buy, we will win 234 pips if we closed our order when the down arrow appeared. but at best we could've earned 289 pips

indicator before modification (original) :

this is how i want it to look like:

IMPORTANT NOTES:

This is an easy task. i will not pay more than $30.
