Part 1 — Shortcut to volatility analysis (Fork method)

Before we build anything from scratch, let’s start with a shortcut.

Because in real trading, you don’t always want to rebuild the wheel.

You want to fork it.

╌╌╌╌

Step 1 — Open Kalshi Weather Market Guide

Go to:

• Kalshi Weather Prediction Markets Guide

From there, open the volatility chart section.

╌╌╌╌

Step 2 — Click “Run for yourself”

This is the key step.

You are now cloning a prebuilt volatility analysis system.

No setup. No configuration. No coding.

Just:

click and replicate

You can also run it directly on any chart inside Lychee:

╌╌╌╌

Step 3 — Pick a market

Search for a market.

We’ll use:

Iga’s Wimbledon win market (non-weather example on purpose)

This is intentional.

Because volatility analysis is not weather-specific — it works across any Kalshi market.

╌╌╌╌

Step 4 — Fork the chart

• Search “Iga Wimbledon”
• Select the market

• Click “Run analysis”

• Click Chart Tab

Now you have:

a fully replicated volatility chart with zero manual setup

This demonstrates the core idea:

volatility analysis is reusable across all prediction markets

╌╌╌╌

Part 2 — Build volatility from scratch (Deep workflow)

Now let’s build the full system manually so you understand what is actually happening under the hood.

We are now using:

Kalshi historical trade data

╌╌╌╌

Step 1 — Find interesting markets to analyze

Open:

• Kalshi Historical Integration

Then click:

• Markets

Select columns:

• Ticker
• Category
• Title
• Volume
• Volume24hrs

╌╌╌╌

Apply filters

Set:

• Category = Weather

We only want weather markets.

This is where we narrow to:

weather-specific prediction behavior

You can explore this whole ecosystem here: https://lycheedata.com/kalshi-historical-data

╌╌╌╌

Sort by Volume24hrs (descending)

This is important.

We are sorting by last 24h trading volume before market close.

Why this matters:

markets become most informative near resolution
traders aggressively correct mispricing as uncertainty collapses
this is where consensus formation happens

So high Volume24hrs usually means:

• strong disagreement earlier in the market
• rapid repricing near settlement
• high informational activity

This is exactly where volatility shows up.

╌╌╌╌

Limit results

Set:

• Limit = 30

We only analyze:

top 30 most active weather markets

Run query.

╌╌╌╌

Step 2 — Pull full trade-level data

Now switch to:

• Kalshi Historical Integration

Select:

• Trades dataset

Select all columns

╌╌╌╌

Apply filters

Set:

• ticker = your selected market

Run query.

Now you have:

full trade-by-trade history of a single Kalshi weather market

╌╌╌╌

Step 3 — Why volatility exists (quick theory)

Before we compute anything:

Volatility is not random noise.

It represents:

• disagreement between traders
• incoming new information
• repricing of probability
• uncertainty compression over time

Mathematically, volatility is often captured using:

standard deviation of returns

But raw prices are not enough.

We need structure.

╌╌╌╌

Step 4 — Convert trades into time buckets

Open:

• Mathematics Operations

Go to:

• Stats tab → Bucket

╌╌╌╌

Configure bucket

Set:

• Column to bucket → Created time
• Bucket style → Time intervals
• Time bucket → 15 minutes

Why 15 minutes?

• 5 min = too noisy
• 60 min = too smooth

So 15 minutes is the balance:

enough signal, not too much noise

╌╌╌╌

Aggregation 1 — Volume per bucket

Set:

• Type → Sum
• Column → Count
• New column → Volume

Meaning:

total contracts traded per 15-minute interval

╌╌╌╌

Aggregation 2 — VWAP (key step)

Set:

• Type → Value Weighted Average (VWAP)
• Value → yes_price
• Weight → count

Why VWAP matters:

It removes:

• micro trade noise
• outliers
• low liquidity distortions

Instead of raw price, we get:

true weighted market consensus per interval

╌╌╌╌

Step 5 — Calculate returns

Open:

• Mathematics Operations → Functions

Create:

• returns = VWAP(t) - VWAP(t-1)

╌╌╌╌

Step 6 — Convert to absolute returns

• Operation → Absolute value
• Column → returns
• New column → abs_return

Why:

volatility is magnitude, not direction

╌╌╌╌

Step 7 — Calculate rolling volatility

Open:

• Stats → Standard Deviation

Set:

• Source column → abs_return
• Mode → Rolling
• Window → 4

Why rolling matters:

Markets are non-stationary.

Rolling volatility captures:

evolving uncertainty over time

4 × 15 min = 1 hour:

hourly volatility signal

╌╌╌╌

Step 8 — Final volatility column

Name:

• Volatility

Apply to sheet.

Now you have:

full time-series volatility of Kalshi weather markets

╌╌╌╌

Step 9 — Visualize volatility

Open Charts and plot volatility.

╌╌╌╌

What this tells you

High volatility:

• news shocks
• disagreement spikes
• repricing events

Low volatility:

• consensus formation
• stable information environment

╌╌╌╌

Key insight

Volatility is not noise.

It is:

the fingerprint of uncertainty in prediction markets

╌╌╌╌

FAQ

What does volatility mean in Kalshi weather markets?

It measures how quickly and strongly market prices change as traders update expectations.

╌╌╌╌

Is higher volatility better for trading?

Not always — it indicates opportunity and risk. High volatility means more disagreement, but also more uncertainty.

╌╌╌╌

Why use rolling volatility instead of full-period standard deviation?

Because markets evolve. Rolling volatility captures changing regimes instead of flattening all data into one average.

╌╌╌╌

Why use VWAP instead of raw price?

VWAP reduces noise from individual trades and gives a more accurate representation of consensus pricing.

╌╌╌╌

Final takeaway

Volatility reveals:

when markets are confident
and when they are uncertain

And that distinction is where trading edges exist.
