Hi the above one is very nice indicator..

little correction to be modified are..

1. if local time it is showing top left corner is covering hiding candles can we place it some where as box so that we drag it to anywhere in chart as box.

2. I can see only integer type.. can u modify it to doubl type so that i can add my local time (ex here in india local time is GMT +5.30 but it is considering 530 so i am unable to place 5hrs 30min)

3. Can u make Vertical lines exactly on the chart window saying that text (vertical text) names of session open and close.

Thank you for your wonderfull indicator and your help.

1. No, Comment() is shown in the top left corner, you can change it to a Label Object and place it where you want.

2. The local time just shows seconds, change it to hours and minutes if you want.

3. what have you tried so far ?

first, 5 hours 30 minutes is not entered as 5.3 ! Think about it.

second, you cannot simply change int to double in that line alone... there will have to be a lot more changes made in the code.

yes may be u r right..

that is First issue. Secondly i have seen that time as per Broker GMT (+3 ) i should see the market starting from 10.00 for Europe and 15.00 for New York. But it shows me starts time of 11 for europe and 16.00o for Newyork. what changes is to be made in input as well as in program.

u are right not a simple double type instead of int. help in tese two issues as stated above. Thanks for your help.
