Vwap Hourly

[shrike]

hi
could someone help me to modify the DBVWAP_SD so i can starting it from a prefix hour like 0900 or 1100 , i've tried much times but nothing

Look for the following code inside the indicator

if date > date[1] then begin


The software evaluates each bar one at a time.
When it reaches a bar that has a different date than the previous bar,
it knows that a new day has begun... and resets the data.


you can change the line to the following:

if time = 0900 then begin

This will do the reset at 0900.

hi
thanks Tams for help , i tried it and work but what i found sometime an error because if i plot it on a range or volume chart sometime where is not a candle at 0900 so or return an error or skip restart when find a candle at 0900 . i try this :
if time = iniz or time =iniz+1 or time =iniz+2 or time =iniz+3 or time =iniz+4 or time =iniz+5 then begin . not elegant but must study more language code

i 've seen one post where you explain a formula with begin_time and end_time , i tried to insert in the code but dont work

Try something like.....

inputs:
iStartTime (0800),
ResetMinutes (60);


if mod( (TimeToMinutes(time)-TimeToMinutes(iStartTime) ), TimeToMinutes(ResetMinute s) ) = 0 then
begin
reset code starts here

thanks BlowFish
make some attempts, what do you mean with reset code starts here

maybe replace : if date > date[1] then begin

with

if mod( (TimeToMinutes(time)-TimeToMinutes(iStartTime) ), TimeToMinutes(ResetMinute s) ) = 0 then
begin

[BlowFish]

Yes, thats pretty much it.
You need the two inputs also.

one logical way to do this is to create a variable that will store the count for the number of bars since a given time or date.

vars: firstbar(0), length(0);

if date > date[1] then begin
firstbar=currentbar;
end;

length=currentbar-firstbar;

--------------------------------------

the above creates a variable called 'firstbar' and stores that information of when the firstbar began so that you can reference it with a second variable 'length'. length is then a changing variable that is the difference between the bar you are on and the first bar of the day. so the code 'average(close,length);' ..... is the simple average close since the day began, counting back more as the number of bars increases. I found this little piece of code very logical.

The advantage of the code I posted is that it allows you to specify any start time and any period (in minutes) to perform the reset. This is irrespective of bar type or size. It works too as I use it in my studies

Here's a 50 contract constant volume chart with resets every hour.
