Maybe I have a problem understanding the IntradayBarIndex. This is what I don’t understand:
- I create a one-time ranger and all is perfect.
- I create a two-time ranger and IntradayBarIndex “does not obey”
In the picture you see
- (the boxes just mark the whole time range)
- the High lines of the Pre market (same time range in both versions).
- The one-time ranger in bold dashes which does start with the IntradayBarIndex value for highestPrice at zero
- the two-time ranger as smaller line which does not start with the IntradayBarIndex value zero.
I thought that setting the IntradayBarIndex once in the beginning would do the job for the whole indicator, means when the first time range (in this case 8:00-9:00) is activated by setting it TRUE we begin calculating with zero.
Am I making a thinking mistake here?
Thanks.
IF IntradayBarIndex = 0 THEN
highestPrice = 0
lowestPrice = close * 100
ENDIF
TimeRange = ( Time > 080000 AND Time < 085959 )
IF TimeRange THEN
highestPrice = max(highestPrice,high)
lowestPrice = min(lowestPrice,low)
ENDIF
RETURN highestPrice as "Buytrigger", lowestPrice as "Selltrigger"
IF IntradayBarIndex = 0 THEN
highestPrice = 0
lowestPrice = close * 100
ENDIF
// --- extern: PreMarket (bool), NormMaket (bool)
PrTimeRange = ( time > 080000 AND time < 085959 )
NoTimeRange = ( time > 090000 AND time < 095959 )
// --- 1st ranger
IF PreMarket THEN
IF PrTimeRange THEN
highestPrice = max(highestPrice,high)
lowestPrice = min(lowestPrice,low)
PrHigh = highestPrice
PrLow = lowestPrice
ENDIF
ENDIF
// --- 2nd ranger
IF NormMarket THEN
IF NoTimeRange THEN
highestPrice = max(highestPrice,high)
lowestPrice = min(lowestPrice,low)
NoHigh = highestPrice
NoLow = lowestPrice
ENDIF
ENDIF
RETURN PrHigh as "PreMarketRange High", PrLow as "PreMarketRange Low", NoHigh as "MarketRange High", NoLow as "MarketRange Low"
You are using 2 times the same variables names (highestprice and lowestprice) and for 2 different time settings, that could cause the difference?

Thanks Nicolas for the idea. But – there is always a but 🙁
I change the code to use two different starting limits and calculate with them. I just show the PreMarket=true in the picture because NormMarket does the same.
- thick blue line is High Line starting only at the beginning of the chart with zero
- dark blue dashes is the Low Line, also starting only at the beginning and not as it should at close*100
The orignal idea of having only one defintion of highest and lowest in the IntradayBarIndex was: as soon as one Ranger is started, it should look up the IntradayBarIndex values and then do its job. If now the second Ranger is started (this one would start later than the first one, so) there is actually no real need for the IntradayBarIndex values as we know already know highs and lows.
Here is the modified code that goes with the picture:
IF IntradayBarIndex = 0 THEN
PRhighestPrice = 0
PRlowestPrice = close * 100
NOhighestPrice = 0
NOlowestPrice = close * 100
ENDIF
// --- extern: PreMarket (bool), NormMarket (bool)
//PreMarket=1
//NormMarket=0
PrTimeRange = ( time > 080000 AND time < 085959 )
NoTimeRange = ( time > 090000 AND time < 095959 )
// --- 1st ranger
IF PreMarket THEN
IF PrTimeRange THEN
PRhighestPrice = max(PRhighestPrice,high)
PRlowestPrice = min(PRlowestPrice,low)
PrHigh = PRhighestPrice
PrLow = PRlowestPrice
ENDIF
ENDIF
// --- 2nd ranger
IF NormMarket THEN
IF NoTimeRange THEN
NOhighestPrice = max(NOhighestPrice,high)
NOlowestPrice = min(NOlowestPrice,low)
NoHigh = NOhighestPrice
NoLow = NOlowestPrice
ENDIF
ENDIF
RETURN PrHigh as "PreMarketRange High", PrLow as "PreMarketRange Low", NoHigh as "MarketRange High", NoLow as "MarketRange Low"
Thanks for your attention.
I am giving you my two cents on this. You are using a TF 30 mins. If Intradaybarindex=0 goes from 0800 till 0830, you will not have any data available for this intradyabarindex until 0830 (close time of the first intraday bar). This means that only after 0830 you will have a good computation of values. I cannot really see the scale on the bottom. If you want to troubleshoot the problem try to add the return line return intradaybarindex
