Draw vertical line at 15min zero second intervals

Is it possible to draw a veticale line at 15min intervals and zero seconds on a chart regardless of the timeframe?

Here's what I have to draw a vertical line at 00:15:00.

It compiles but MT4 locks up, what a surprise with the things I try to do...any thoughts???

Hi Palmer,

I wrote a similar set-up for myself and posted it for a fellow who requested it.

http://www.forexfactory.com/showthread.php?t=51981

I did it by using ObjectCreate(...). Check the code and adjust accordingly. If you still need help let me know and I will help.

If you are using this on one minute charts or five minute charts I would suggest adding a clause at the beggining of int start that checks what chart timeframe the indicator is being applied to as it would not be any help in any chart with a 15 minute timeframe or more. Using the Period() function will return the timeframe of the current chart the indicator is on and can be used to void the code if the timeframe is not 1 minute or 5 minutes.

Otherwise if you are looking for 00:15, 01:15, 02:15 I am sure the code can be slightly adjusted to add the minute clause.

Thanks boss! I'll look 'into' it and let you know...

Here's my hack of lucidlamp's indicator. I added the 15min extern ints at 00,15,30,45 and that was it. Not sure how to combine all of the 'ifs' for one statement but either way it works.

Some of the spacing is a little off with the total 1 minute bars that are supposed to equal 15 individual bars because there was no price change for that minute where the minute was equal to 00, 15, 30, or 45. Easier to see it on the chart vs. explain it...

Thanks lucid!

Hi Again,

I tried to clean up the code and I came up with a method using iBarShift(), but then I realized that the seperators were being every 15 or 3 bars, depending on 1 minute or 5 minute timeframe, respectively, which would skew the seperators (especially on a 1 minute chart).

ps: This should do the same as the modifications you did, although it looks a little cleaner:

hi!
i am looking for an indicator, that will draw vertical lines in specific time intervals not bars. for example every 20 minutes and the it will take into account the weekend time as well. it just needs 2 variables start time and interval size in minutes.

i hope someone can help me!
thanks in advance

either above indis or find Paramon work time, maxigen, sessions, specific time zone breakout indis;etc
should be around

thank you nice 4 indis;
btw. would be nice feature to extend vert. lines beyond zero bar point - can show visually (on lower TFs) how far to certain bar end

i just ran accross this thread, though id give a crack at it

ok heres the inputs

tf=0
start_minute=0
interval=15
input for tf like this 15-30-60-240-1440-10080-43200 one year is 518400
set tf to 0 to use interval
interval only works for 60 minutes or less. it will accept seconds 0.01 is 1 second 1 is one minute

setting anything other than 0 in the tf, will disable the interval

seems to work fine, i havent tested on a live market
lemme know if theres any problems, feel free to edit the file
if you edit it, you should rename it

hmm, not sure how to do that
il look into it

ok it seems good, no more seconds, but its drawing the future lines

Thank you TC- yeapp work like a charm
be-a-utiful
i just added some user inputs routine stuff
ObjectDelete("future"); - just left -over?
we might need 2limit objects like 100 or few screens - later on
cool, nice, thank you

yeah that was a leftover lol
glad you like it

+ adds an ons: maxbars, width, onbackgr...

Thanx for the indie dudes. FXXX, i especially like that it draws into the future....but its somehow not playing nice with me. On my 1min chart, when i set the tf to 0 and interval is on 15 it draws v-lines on ##:15 and ##:45 of every hour.
What i would like it to do is simply draw a line every 15 bars starting on the hour(on a 1min chart) and on every 3rd bar starting on the hour(on a 5min chart). In other words, draw a v line every 15mins no matter the tf.

I primarily trade binary options and would like to have lines on the expiry times, which at my broker is every 15 mins except for the EURUSD that expires every 10 mins. I would be great if I could set the intervals to either 15 or 10 mins.

Could you pls have a look into that. I wish i understood coding so that i could rewrite it myself...but you guys are waaay smarter than me...

Much obliged

I know this is years old, but I just found it today and love it! It was just what i was looking for. I use it to draw 1 hour lines on my 15min charts.

Finally found what I was looking for thank you very much for creating such tool.
Latest version is works well for me.

Is it possible to insert a 2 Feature?
I would like to use the VL's more as a Number of Candle-lines .
So lets say I draw a VL than the Indicator draw the VL-lines every 50 Candles (customizable in the Indicator-settings-window) in the future (and in the past for X bars for backtesting)
Thanks for an info.
Regards Zack

Not sure if this is what yo Zack-
Try this.
Drag the line to a new position. The additional lines will be drawn at intervals specified in the user inputs and will stay until you drag to a new position.
