This is about longer-time frame charts overlaid on shorter; I need settings to prevent source from over-writing Rows 4+ in destination chart. I've studied SC responses to similar problems,such as https://www.sierrachart.com/supportboard/showthread.php?t=39926 I've tried all the Study Overlay settings and combinations and read support posts & the documentation 3 times. My source & destination use the same Auto-Trade Spreadsheet and same time frames, but the destination does the trades. The problem is: I use a 3-Line Break study in the source chart which acts like a longer-period chart, erasing prior output destination values. Others have this issue when longer bar periods are Study-Overlayed onto short-period charts with Spreadsheets. In their case, the longer source values post on down the destination column for as long as the one source bar updates (like mine does). That writes over Rows 4 - 9+ values (however long a source bar lasts). This throws off averages and backtesting. The top row always reflects current values from both charts. In mine, chart periods for destination & source are same, but my source chart's 3-Line Break Study creates longer "virtual" variable-period bars. A 3-Line Break study can have 10+ bars before a new bar shows up, or just 1 or 2. I need the 3-Line Break source column instant value "as of" the end of each usually-shorter destination bar, via overlay--- for each value during what "appears" a longer 3-Bar study bar. I think this works much like just like any longer-period-chart onto a shorter destination. I've tried. Please help find settings that solve this for all of us needing longer charts onto shorter. This is essential for trend-monitoring oversight and control over shorter auto-trade charts, especially when trading intrabar on the short timeframe. Data events during 2 to 5 minutes are crucial, as are instantaneous values from longer-charts. We can't have backtesting break down because there is no setting (that I can find) to "Hold Instant-interim Source Values as of Per Each Destination Row" (per End of Dest. bar). (or, programatically: Just don't write beyond current top destination row & keep last as-of value per EOB destination row change) EOB=end of bar Backtesting reliability of Moving averages & LinReg Slopes are important to develop winning systems. Also, per-row audit analysis is essential to finding trigger conditions/debugging under sheet "detail". I apologize if I missed the setting combination, but I've tried several ways for nearly 2 days.
