Post From: VWAP study producing incorrect standard deviation bands on GC (Denali feed)

I'm experiencing intermittent corruption of VWAP standard deviation bands on Gold futures. The issue has occurred at least twice recently and affects all charts in the same chartbook that share the symbol simultaneously. Setup: Symbol: GCQ6.COMEX[M]/MGCQ6.COMEX [CBV][M] Data feed: Denali exchange data Study: EC|VwapV1.5 (Study ID: 63) Affected timeframes: 30 Min and 1 Min charts in the same chartbook (confirmed on both) Also observed on higher timeframes (120 Min, 480 Min, Daily) in a separate 4-chart layout Problem: The VWAP standard deviation bands intermittently become far too wide — for example, the lower bands extending 70+ points below price when they should be within ~20 points. The VWAP line itself may also be affected. The corruption appears to happen randomly (not tied to session open, reconnect, or any specific time of day) and affects all charts displaying the same symbol simultaneously. Workaround: Performing Edit → Reload and Recalculate immediately fixes the bands on all affected charts. The corrected values are clearly correct compared to the corrupted state. I only observed on GC, not on other instruments yet. I have before/after screenshots available showing the corruption and the corrected state across multiple timeframes if needed. Got the exact same settings on other symbols without that problem. Thank you! |
