Why people use ATR-Calculator
Stop manual volatility math with ATR-Calculator
With this MCP, you just hand the raw numbers to your agent. It checks the data for errors, runs the math, and tells you exactly how volatile the market is. You get a clear answer instead of a spreadsheet full of formulas.
What Vinkius changes
You get instant, mathematically accurate volatility metrics from raw price data.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

- Real-world use case 01
Adjusting stop-losses for high volatility
A trader notices a sudden spike in movement and asks their agent to calculate the ATR to set a wider stop-loss that won't get hunted.
- Real-world use case 02
Cleaning messy data feeds
An analyst has a corrupted CSV of prices and uses the agent to validate the data before attempting to run a strategy.
- Real-world use case 03
Identifying breakout opportunities
A user checks if current volatility is hitting historical highs to confirm a true market breakout.

Before you connect
Questions about ATR-Calculator.
The practical details behind the request, access and result.
How can I use ATR-Calculator to analyze market movement?
You can provide price data to your agent, and it will use the ATR-Calculator MCP to determine the Average True Range as a percentage and classify the volatility level.
Can this MCP help me check for errors in my trading data?
Yes, it includes a capability specifically designed to validate price arrays, ensuring your high, low, and close prices are mathematically consistent before you perform analysis.
How does ATR-Calculator define high volatility?
Volatility is classified as high when the calculated ATR exceeds the historical percentile boundaries retrieved for that specific dataset.
Is it possible to compare volatility between two different stocks?
Yes, because the capability calculates ATR as a percentage of the price, you can compare the relative volatility of a cheap stock against an expensive one accurately.
Can I use ATR-Calculator with Claude or Cursor?
Yes, as long as you are using an MCP-compatible client like Claude, Cursor, or Windsurf, you can connect this MCP and start running volatility calculations immediately.
What is the difference between the smoothing methods?
The server supports Wilder's smoothing (the traditional method), Simple Moving Average (SMA), and Exponential Moving Average (EMA).
How is volatility classified?
Volatility is classified as low, medium, or high based on where the current ATR percentage sits within the historical distribution of the provided data.
Can I validate my price data before calculating ATR?
Yes, you can use the validate_price_data capability to check if your high, low, and close price arrays are consistent and valid.
