Re: [amibroker] Plot Vertical Line at Trading_Day_Interval(n)

To me, only calendar days made sense given that Trading Periods don't fall on weekends.

The problem was
 
"How does one code a loop to plot vertical line beginning on a particular period in the past
and then redraw the same vertical line at a given interval in (n) Trading Periods 
 
with "n Trading Periods" I would think that he meant trading days (i.e. bars), not calendar days.

I believe he asked for calendar days adjusted to nearest weekday.

Hello,
 
Please use modulo (%) operator:
 
 
zStartDate = Month()==01 AND Day() == 02 ; // Start Period on a Daily Chart for example
 
zStartDate = ( BarsSince( zStartDate ) % 12 ) == 0;
 
Plot(zStartDate * Close,"Start Date",6,6 | styleNoLabel); // I got this far...

How does one code a loop to plot vertical line beginning on a particular period in the past
and then redraw the same vertical line at a given interval in (n) Trading Periods so it does not fall on a weekend? 
( I suppose if it falls on Saturday, plot on Friday before and if it falls on Sunday, plot it on Monday.
 
Let's say I replot the vertical line every 12 days,but want to avoid weekends...
 
Is there a better function that would take care of it for both intraday and daily intervals?
 
////////////////// Vertical Line Plot for Starting Seed
zStartDate = Month()==01 AND Day() == 02 ; // Start Period on a Daily Chart for example
Plot(zStartDate * Close,"Start Date",6,6 | styleNoLabel); // I got this far...
 
Thanks,
 
Mr Valley
