3 functions

I apologise for my english.

i hope it is clear enough

I need 3 functions I will use in an EA.

I will manualy draw lines on charts (lets say Dodger blue lines)

Function 1

bool      Is_current_price_near_Dodger_blue_line ( )

(near=within x% above/below line)

return(true/false)

Function 2

double   Check_for_next_line_above_just_touched_line( )

return (price line)

if no line above

return(-1)

Function 3

double Check_for_next_line_below_just_touched_line( )

return (price line)

if no line below

return(-1)

Could you do this job for me?

Thank you
