Marking highs and lows based on opening and closing prices.

theunpredictable · 2025-12-23T08:53:51+00:00

Hi, Do you have any ideas on how to mark the high and low of a time range, e.g., 8 a.m. to 12 p.m., on the chart? It is important that the highs and lows are marked only on the basis of the candle bodies, i.e., without wicks and shadows. I wrote it once on a closing price basis. However, it is sometimes the case that the opening prices mark the lower or upper end, and then the line is not correct. // Dailyreset IF Day <> Day[1] THEN hiClose = Close loClose = Close ENDIF // Collecting only between 08:00 and 14:30 IF Time >= 080000 AND Time = 143000 THEN DRAWSEGMENT(barindex, hiClose, barindex + 1, hiClose) COLOURED(165,42,42)style(dottedline, 3) DRAWSEGMENT(barindex, loClose, barindex + 1, loClose) COLOURED(165,42,42)style(dottedline, 3) ENDIF

Hi,

It is important that the highs and lows are marked only on the basis of the candle bodies, i.e., without wicks and shadows. I wrote it once on a closing price basis. However, it is sometimes the case that the opening prices mark the lower or upper end, and then the line is not correct.

// Dailyreset
IF Day <> Day[1] THEN
hiClose = Close
loClose = Close
ENDIF

// Collecting only between 08:00 and 14:30
IF Time >= 080000 AND Time <= 143000 THEN
hiClose = MAX(hiClose, Close)
loClose = MIN(loClose, Close)
ENDIF

// Drawing Line from 14:30
IF Time >= 143000 THEN
DRAWSEGMENT(barindex, hiClose, barindex + 1, hiClose) COLOURED(165,42,42)style(dottedline, 3)
DRAWSEGMENT(barindex, loClose, barindex + 1, loClose) COLOURED(165,42,42)style(dottedline, 3)
ENDIF

There you go:
```
// Dailyreset
//IF Day <> Day[1] THEN
//hiClose = Close
//loClose = Close
//ENDIF

// Collecting only between 08:00 and 12:00
IF OpenTime >= 080000 AND OpenTime <= 120000 THEN
   if OpenTime = 080000 THEN
      hiClose = Close
      loClose = Close
   endif
   hiClose = MAX(hiClose, Close)
   loClose = MIN(loClose, Close)
ENDIF

// Drawing Line from 12:00
IF OpenTime >= 120000 THEN
   DRAWSEGMENT(barindex, hiClose, barindex + 1, hiClose) COLOURED(165,42,42)style(dottedline, 3)
   DRAWSEGMENT(barindex, loClose, barindex + 1, loClose) COLOURED(165,42,42)style(dottedline, 3)
ENDIF
return
```

Please select the correct language. I moved it from the German forum. Thanks 🙂

Hi Roberto,

I probably didn’t express myself clearly.

However, the formula you showed only depicts the range in the period shown on a close basis.

In the image, you can see that the range would be higher if you also wanted to use the open (high, low).

In other words, I want to see the lowest price and the highest price of all candlesticks in the period. I don’t know how to include the open price in the calculation.
