Problem extending Market Session Open lines over the weekend

[Carla]

Hello,

I am novice coder and trying to modify market session indicator (by Adam Jowett).

My intended modification was to draw market session open line for 48hrs. But having problem if Open is Friday lines and 48hrs includes weekend.

below is what I wrote - if Friday, extend line for 72hrs. but this code affects all weekdays.

if (TimeDayOfWeek(currentTime)==5)sessionLengthb = Period() * 60 * ((60 / Period()) * 72);

Your advice is greatly appreciated.

Carla

for reference below is other part of codes

int init()
{
   sessionLength = Period() * 60 * ((60 / Period()) * 48);//length of extention - 48hours
   sessionLengthb = Period() * 60 * ((60 / Period()) * 24);
   
   sydneyHour = getHour(sydney);
   tokyoHour = getHour(tokyo);
   newyorkHour = getHour(newyork);
   londonHour = getHour(london);
   
   sydneyMinute = getMinute(sydney);
   tokyoMinute = getMinute(tokyo);
   londonMinute = getMinute(london);
   nyMinute = getMinute(newyork);
   
   if (sydneyHour > -1)
   {
      sydneyHour = sydneyHour + gmtServerOffset;
      if (sydneyHour > 23) sydneyHour = sydneyHour - 24;
      if (sydneyHour < 0) sydneyHour = sydneyHour + 24;
   }
   
   if (tokyoHour > -1)
   {
      tokyoHour = tokyoHour + gmtServerOffset;
      if (tokyoHour > 23) tokyoHour = tokyoHour - 24;
