# How to get a time of High/Low of previous day?

27

Hi,

I'm trying to automate analizing charts and to develop some tools for that purpose.

But I can't find a time (lets say an Hour) of High/Low of previous day on the H1 chart.

I used iHigh and iLow functions to find extremes on a D1 chart, but I have no idea how to find a particular time of them. :(

Do you have any idea how to do it?

Use iHighest() & iLowest() to get the bar numbers of the High and Low bars and then you can use Time[bar_number] or iTime()

1. As long has you have D1 history (for the tester, and handle ERR_HISTORY_WILL_UPDATED for live) you can use:
`double HHyest = iHigh(NULL, PERIOD_D1, 1);`

2. Alternatively, (for offline charts, etc)
```#define HR2400      86400           // 24 * 3600
datetime TimeOfDay(datetime when){  return( when % HR2400          );       }
datetime DateOfDay(datetime when){  return( when - TimeOfDay(when) );       }
//////
datetime  now   = TimeCurrent(),
bod    = DateOfDay(now),
yest   = DateOfDay(bod-1);
int      iBod   = iBarShift(NULL,0, bod),
iYest  = iBarShift(NULL,0, yest),
iHHy   = iHighest(NULL,0,MODE_HIGH, iYest-iBod, iBod+1);
double   HHyest = High[iHighest];```

Thanks a lot :)

Nice idea. I tried it and it works:)

Can give an idea of how to stop iHighest/iLowest  from giving a signal past the last higest/lowest, ie... lowest on an uptrend? Any help would be much appreciated. Thanks.

I don't understand what you are asking for.
