HTF FVGs (UDT) [CantoLab]

A multi-timeframe extension of the FVG Detector (UDT) — plots Fair Value Gaps across up to 6 timeframes at once, still built the same way: using User-Defined Types (UDTs) so the detection, drawing, mitigation, and state-tracking logic are all just function/method calls instead of repeated inline logic.

What's different from the single-timeframe version

Instead of writing a separate request.security call for each timeframe, this uses a single reusable function that takes a timeframe as a parameter and is looped through for all 6 timeframes.

It also adds a getBar function, this solves a specific problem with HTF FVGs: the gap is detected on the higher timeframe, but if you just use the HTF bar's open time to place the box, it doesn't line up with the actual candle that created the high or low. getBar walks forward through the lower-timeframe bars to find the exact candle that produced that price, so the FVG box is drawn precisely where the gap actually formed.

Everything else is the same as the FVG Detector :
Standard 3-candle FVG detection
Boxes with optional border, mid-line, and labels
Mitigated FVGs are removed automatically, with an option to keep them visible in a muted state
