Below is just for reference: (only partial solution, I think may need to loop
thru the array further and remove some unwanted intraday values, so the signal
will show only once per relevant condition. ) However, I don't know how to
write: maybe someone will post more complete solution.)
To calculate AA:
yestodayClose= TimeFrameGetPrice("C",inDaily,-1);
dayBfYtdClose = TimeFrameGetPrice("C",inDaily,-2); // day before yesterday's
close
diffAA = 100 * (yestodayClose - dayBfYtdClose) / dayBfYtdClose; // the percent
difference
AA = diffAA > 0;
To calculate BB: (the deDateTime plugin is needed)
todayClose = deValueWhenTime(Close,160000); // suppose market close at 16:00:
get the last bar close price
todayClose1 = deValueWhenTime(Close,155900); // one bar before last bar's
close price
diffBB = 100 * (todayClose - todayClose1) / todayClose1; // the percent
difference
BB = diffBB > 0;

Subject: [amibroker] Amibroker help
In the following formulae, I want to show in place of 'AA' the percent
difference between yesterday's close price with that of the day before
yesterday. And in place of 'BB' I want to show the percent difference between
close price of today's just previous intraday bar with that of the one just
before it.
PlotShapes( IIf( AA, shapeUpArrow, shapeNone ) , colorGreen );
PlotShapes( IIf( BB, shapeHollowUpArrow, shapeNone ) , colorGreen );
Can anyone please tell me what to write?
Thanks,
Vinay Gakkhar
