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
