Non-Repainting Fair Value Gap FVG For ThinkOrSwim

Non-Repainting Fair Value Gap FVG

mod note:
What the Script Does Well
1. Multi-Timeframe Confluence Visualizer

Overlaying 15m, 30m, and 60m Fair Value Gaps directly onto a lower-timeframe chart (like a 1m or 2m) gives intraday traders immediate visibility into key higher-timeframe liquidity gaps without having to constantly flip between chart tabs.​

2. Automated FVG Tracking & Invalidation

By implementing state variables (bullFilled15, bearFilled15), the script dynamically removes ("extinguishes") the cloud once price fills or overlaps the gap. This keeps your chart clean by automatically clearing out historic gaps that are no longer active.​

3. Noise Filtering via minTicks

The inclusion of input minTicks = 1; ensures micro-gaps (1 tick size) don't clutter your screen, allowing you to set a custom minimum threshold for what constitutes a meaningful market inefficiency.​

4. Efficient Cloud Overlay Approach

Using hidden plots (.Hide()) paired with AddCloud() bypasses Thinkorswim's native limits on line clutter and provides clean, clear visual support and resistance zones.​

I had AI put this together this morning. I'm not sure if it's measuring correctly or working. It is supposed to measure 15, 30 and 60-minute FVG. I have no math skills but ask AI and keep working on a script so it doesn't throw any error codes.

Thanks, need to remember the search feature "+"

Throughout the web—including UseThinkScript—almost all Fair Value Gap (FVG) studies repaint.

This happens because you simply can't identify a true gap until all 3 candles have printed. Many studies then go back in time to plant an arrow or box on a prior candle—making them look like the absolute Holy Grail in hindsight.

The Good News About This Script:
Yes, @BillW, your script is using the right math.
But more importantly, it does not repaint!
