Post From: help creating 3 security difference butterfly chart

i want to create a candle chart fly (A*sec1 - B*sec2 - C*sec3) where A,B,C are multipliers, and sec1,2,3 are the prices of different securities

i thought the "Difference Single Line" study http://www.sierrachart.com/index.php?page=doc/helpdetails61.html might be able to do this, but there is only 1 option for another security in the study settings (Chart1 and Chart2).

So, how can i create a chart of this custom-weighted 3 security portfolio?

I've tried nesting using the Difference (Single Line) Study to create this...but i'm not quite there.

Since i am subtracting B*Sec2 + C*Sec3 from A*Sec1, i created a new chart #4 with the Study - Difference (Single Line), where Chart#1 = Sec2 and Chart #2 = Sec3, with a negative #2 multiplier (so, its really just adding the prices of B*Sec2 and C*Sec3). I set the option to "display as main price graph" and This works in creating this step (the value of the chart#4 = B*sec2 + C*sec3). So, this seems to be half the battle...

However, now i want to go back to the chart for Sec1 (chart #3), added the study Difference (Single Line), where Chart#2 = Chart#4 (B*Sec2 + C*Sec3).

However, this results in the underlying security from chart #4 (not my study...but the primary security of the chart) being spread from the chart #3. However, since on chart #4, i've selected "display as main price graph"...i was expecting the value i see in the chart #4 main price graph (B*Sec2 + C*Sec3) to be subtracted from chart#3 A*Sec1.

So, what am i missing? What do i need to do to get Chart3 to recognize the "Study" from Chart #4 as the "value" of chart #4, rather than the primary security of the chart?

I also tried doing it all in one chart as i read in the "High Accuracy Spread" help topic...adding a 2nd "Study - Difference (Single Line)" based on the 1st "Study - Difference (Single Line)" on the same chart...when i set the 1st study to "display as main price graph" and then hide this 1st study, i can then add the 2nd study, and "difference" off the 1st study, and this shows the correct portfolio data after i set the time frame to be 10 seconds. But i now want to see 15min candles for this package to show the range traded in the 15min candles (the 3 original charts are set at 10 seconds)...so i duplicated chart #4 (now we are looking at chart #5), added the "Study - Overlay OHLC", based on the 2nd "Study - Difference (Single Line)" set the timeframe to 15min ...but all i see are dots of the data points...where i was expecting to see candles?

also...even more messed up...chart #4 and chart #5 not showing the same value for the same fly?
Chart#4 2 "Study - Difference (Single Line)" nested, is using 1 second data time-frame...Chart #5 5min....and the last data point is not matching?

when i calc the last point manually...i agree with the 1 second chart...but the 5min chart last value is not correct.
Chart #5 was a duplicate of Chart #4, but then i changed the timeframe to be normal, such as 5min.
