The magnitude of the spikes indicate the strength of the swap expiration. The more volatile the spikes, the more volatile the resultant price action might be.
This indicator does not catch all positive price increases, but only looks for swap expirations.
It also does not know what the options chain looks like, so a volatile options chain will make this indicator not show any spikes during that timeframe (see May-June 2024)
It also does not account for company actions like share offerings.
The indicator is only valid after Jan 2021.
The indicator gives a guideline with red/orange warnings on the trendline but you can use your own eyes to try and see when it is showing approaching volatility. The red and orange marks were added after the fact to try and make it a little more user friendly.
It was tuned to work on the DAILY timeframe. Using anything less than the daily timeframe is untested and likely not valid.
This is also just an indicator and does not predict the future. It is not guaranteed to work in the future, although it has done pretty well in the past.
